Full opinion text

Justice Lehrmann delivered the opinion of the Court, in which Chief Justice Hecht, Justice Devine, Justice Brown, and Justice Blacklock joined.

This action stems from a contract dispute over an offset provision in an oil and gas lease. The court of appeals held that the lessee did not conclusively demonstrate compliance with the provision and reversed the trial court's summary judgment in the lessee's favor. Because the court of appeals read a requirement into the lease that its unambiguous language does not support, we reverse the court's judgment.

I. Background

Shirley Mae Herbst Adams and William Albert Herbst entered into essentially identical oil and gas leases with Murphy Exploration & Production Company's predecessor-in-interest. The leases cover two contiguous 302-acre tracts in Atascosa County. The leases each contain a provision obligating Murphy to either drill an offset well, pay royalties, or release acreage in the event a producing well is completed on an adjacent tract within 467 feet of the leased tracts. In its entirety, the offset provision states:

It is hereby specifically agreed and stipulated that in the event a well is completed as a producer of oil and/or gas on land adjacent and contiguous to the leased premises, and within 467 feet of the premises covered by this lease, that Lessee herein is hereby obligated to, within 120 days after the completion date of the well or wells on the adjacent acreage, as follows:

(1) to commence drilling operations on the leased acreage and thereafter continue the drilling of such off-set well or wells with due diligence to a depth adequate to test the same formation from which the well or wells are producing from [sic] on the adjacent acreage; or

(2) pay the Lessor royalties as provided for in this lease as if an equivalent amount of production of oil and/or gas were being obtained from the off-set location on these leased premises as that which is being produced from the adjacent well or wells; or

(3) release an amount of acreage sufficient to constitute a spacing unit equivalent in size to the spacing unit that would be allocated under this lease to such well or wells on the adjacent lands, as to the zones or strata producing in such adjacent well.

Comstock Oil & Gas, LP drilled a producing horizontal well (the Lucas well) on the tract adjacent to and southwest of the tracts covered by the leases. The Lucas well, which was landed in the Eagle Ford Shale formation, is 350 feet from the lease boundary and thus triggered the offset provision. Rather than pay royalties based on the Lucas well's production or release acreage, Murphy chose to exercise the provision's first option and commenced drilling operations. Specifically, within 120 days of the Lucas well's completion date, Murphy commenced drilling a horizontal well (the Herbst well) on the leased acreage. It is undisputed that the Herbst well was also landed in the Eagle Ford Shale formation and was thus drilled "to a depth adequate to test the same formation" from which the Lucas well was producing. However, the Herbst well is approximately 1,800 feet from the pertinent lease line. The horizontal laterals of both wells run parallel to the lease line.

Murphy completed the Herbst well in November 2012 and began paying royalties on production. Six months later, the lessors and royalty owners under the leases (collectively, Herbst) sued Murphy for breach of contract, alleging that Murphy failed to comply with the offset provision. Murphy counterclaimed, seeking declaratory relief regarding its obligations under and compliance with the leases. The parties filed cross-motions for partial summary judgment. Herbst argued that the Herbst well is too far from the lease boundary to qualify as an offset well, in light of both the common meaning of the term "offset" and the oil and gas industry's understanding of the term "offset well" as a well intended to protect against drainage.

Murphy asserted that the provision imposes no location or minimum spacing requirement for the offset well; it requires only that the well be drilled "on the leased acreage" and "to a depth adequate to test the same formation from which the well or wells are producing from [sic] on the adjacent acreage." Murphy thus argued that this provision, "drafted with horizontal shale wells in mind, only require[s] the lessee to counterbalance (or offset) production from the tight shale formation, recognizing that there is little to no drainage in the Eagle Ford shale, and therefore no reason to locate the offset well near the lease line."

The trial court granted Murphy's motion, denied Herbst's, and rendered a final judgment granting Murphy declaratory relief and awarding Murphy costs and conditional appellate attorney's fees, but no trial court fees. Herbst appealed, challenging both the summary judgment and the award of attorney's fees. The court of appeals reversed and remanded, holding that Murphy did not conclusively prove that it complied with the offset provision and thus was not entitled to summary judgment. 497 S.W.3d 510, 511 (Tex. App.-San Antonio 2016). The court did not reach the merits of Herbst's independent challenges to the fee award. Id. at 517. We granted Murphy's petition for review. In this Court, Murphy affirmatively waives its claim to conditional appellate attorney's fees.

II. Discussion

A. Standard of Review

We review a trial court's summary judgment de novo. Valence Operating Co. v. Dorsett , 164 S.W.3d 656, 661 (Tex. 2005). Summary judgment is appropriate when no genuine issue of material fact exists and the movant is entitled to judgment as a matter of law on the issues presented. TEX. R. CIV. P. 166a(c). A defendant may obtain summary judgment by, among other things, conclusively negating at least one element of the plaintiff's cause of action. Frost Nat'l Bank v. Fernandez , 315 S.W.3d 494, 508 (Tex. 2010). In reviewing a summary judgment, we take as true all evidence favorable to the nonmovant, indulging every reasonable inference and resolving any doubts in the nonmovant's favor. Valence Operating Co. , 164 S.W.3d at 661.

In this breach-of-contract case, Murphy's compliance with the leases, or lack thereof, hinges on the proper interpretation of those leases. In construing an oil and gas lease, as with any contract, our task is to "ascertain the true intentions of the parties as expressed in the writing itself." Italian Cowboy Partners, Ltd. v. Prudential Ins. Co. of Am. , 341 S.W.3d 323, 333 (Tex. 2011). This analysis begins with the contract's express language. Id. We "examine and consider the entire writing in an effort to harmonize and give effect to all the provisions of the contract so that none will be rendered meaningless." Seagull Energy E & P, Inc. v. Eland Energy , 207 S.W.3d 342, 345 (Tex. 2006) (emphasis removed) (quoting Coker v. Coker , 650 S.W.2d 391, 393 (Tex. 1983) ). We "give terms their plain, ordinary, and generally accepted meaning unless the instrument shows that the parties used them in a technical or different sense." Heritage Res., Inc. v. NationsBank , 939 S.W.2d 118, 121 (Tex. 1996). Addressing oil and gas leases in particular, we have explained that where the lease "expressly defines the duty, we will not impose a more stringent obligation unless it is clear that the parties intended to [do so]." Exxon Corp. v. Emerald Oil & Gas Co. , 348 S.W.3d 194, 215 (Tex. 2011).

Further, we may "consult the facts and circumstances surrounding a negotiated contract's execution to aid the interpretation of its language." URI, Inc. v. Kleberg County , 543 S.W.3d 755, 757 (Tex. 2018). That is, we may consider "objectively determinable facts and circumstances that contextualize the parties' transaction" and "inform" the meaning of the language used, but we may not use surrounding circumstances to alter or contradict an unambiguous contract's terms. Id. at 758 ; see also First Bank v. Brumitt , 519 S.W.3d 95, 110 (Tex. 2017) ("[C]ourts may not rely on evidence of surrounding circumstances to make the language say what it unambiguously does not say.").

B. Analysis

Here, the pertinent lease provision states that if "a well is completed as a producer of oil and/or gas on land adjacent and contiguous to the leased premises, and within 467 feet of the premises covered by this lease," then within 120 days of the well's completion Murphy must "commence drilling operations on the leased acreage and thereafter continue the drilling of such off-set well or wells with due diligence to a depth adequate to test the same formation from which the well or wells are producing from [sic] on the adjacent acreage." The parties do not dispute that Murphy commenced drilling operations on the leased acreage within 120 days after the Lucas well's completion, nor do they dispute that Murphy continued drilling the Herbst well "with due diligence to a depth adequate to test the same formation" as the triggering well. On this record, the trial court concluded that "Murphy complied with the specific terms of the lease," which placed no restriction on the offset well's location "in terms of how many feet from the lease line."

The court of appeals disagreed, holding that Murphy did not conclusively establish the Herbst well satisfied the "commonly understood meaning" of the term "offset well." 497 S.W.3d at 514. Noting that an offset well is generally recognized as a well that protects against drainage, id. at 514-15, the court held that Murphy's summary judgment burden was "to conclusively prove the Herbst well was protecting the [leased] tracts from drainage by the Lucas well," id. at 515-16. Without such a showing, the court concluded Murphy did not prove as a matter of law that the Herbst well was an offset well as the leases required and Murphy thus was not entitled to summary judgment. Id. at 517.

Taking a different but related approach, Herbst contends that the provision at issue, which is triggered by a producing well within 467 feet of the lease boundary, is intended to protect against the risk of drainage while eliminating any dispute over whether drainage is in fact occurring. In light of that purported purpose, Herbst argues that an offset well "must be in close proximity to the lease line adjacent to the tract where the neighboring well is located." Herbst maintains that the Herbst well, drilled 1,800 feet away from the lease line and 2,100 feet from the triggering Lucas well, necessarily did not "offset" that well.

Both the court of appeals' and Herbst's interpretations of the provision at issue depend on the significance of its inclusion of the term "off-set well." We have recognized that drilling an offset well can be a method of protecting against drainage, which occurs when a well produces oil or gas that migrates from another owner's property. E.g. , Kerr-McGee Corp. v. Helton , 133 S.W.3d 245, 253 (Tex. 2004) ("Drainage may be prevented by drilling an offset well."); Lenape Res. v. Tenn. Gas Pipeline , 925 S.W.2d 565, 583 (Tex. 1996) (noting that an operator's implied duty to protect the leasehold from drainage "could give rise to a duty to drill an offset well under certain circumstances"). However, the provision's only specific requirements with respect to where to drill "such off-set well" are that it be "on the leased acreage" and "to a depth adequate to test the same formation" from which the triggering well is producing. The clause does not reference drainage. Nor, in contrast to the express proximity requirement for the triggering well ("within 467 feet" of the lease boundary), does the provision place such a restriction on the well Murphy must drill in response. Murphy thus maintains that it did exactly what the plain language of the leases requires in order to "offset," i.e., "counterbalance" or "compensate" for, the Lucas well's production. Offset , WEBSTER'S THIRD INT'L DICTIONARY 1567 (2002).

Considering the leases' express requirements in light of the horizontal-drilling context in which the leases were executed, we agree with Murphy that it complied with the offset provision as a matter of law. Neither the court of appeals' reading of the provision to require a showing of actual protection against drainage nor Herbst's reading of it to contain an implied proximity requirement is a reasonable interpretation of the language the parties chose.

1. Context

The leases were executed in 2009, and as noted, Herbst does not dispute that they were drafted with horizontal shale drilling in mind. The realities of this type of drilling are thus part of the "facts and circumstances surrounding the contract's execution" that may "inform" our construction of the lease language. URI, Inc. , 543 S.W.3d at 757-58, 765 (explaining that such circumstances can "provide context that elucidates the meaning of the words employed" but cannot be used to "add[ ] to, alter[ ], or contradict[ ] the contract's text"); see also Hous. Expl. Co. v. Wellington Underwriting Agencies, Ltd. , 352 S.W.3d 462, 469 (Tex. 2011) (noting that such circumstances include "the commercial or other setting in which the contract was negotiated and other objectively determinable factors that give a context to the transaction between the parties").

Both the implied covenant to protect against drainage and express lease provisions serving a similar purpose arose in the context of vertical wells, which effectively drain[ ] a surrounding area exhibiting high natural porosity and permeability." Benjamin Holliday, New Oil and Old Laws: Problems in Allocation of Production to Owners of Non-Participating Royalty Interests in the Era of Horizontal Drilling , 44 ST. MARY'S L.J. 771, 813 (2013). By contrast, horizontal drilling in conjunction with hydraulic fracturing allows developers to profitably extract oil and gas directly from the less permeable source rock. See Bret Wells, Please Give Us One More Oil Boom-I Promise Not to Screw It Up This Time: The Broken Promise of Casinghead Gas Flaring in the Eagle Ford Shale , 9 TEX. J. OIL GAS & ENERGY L. 319, 348 (2013-2014). The locations of both the vertical portion of a horizontal well and the nonperforated portions of the horizontal wellbore are essentially irrelevant for production purposes. Rather, the perforated portions of the horizontal wellbore are the points at which oil and gas is drained and produced from the surrounding rock. See Holliday, 44 ST. MARY'S L.J. at 779. Further, commentators have recognized that hydrocarbons in "the tight reservoirs developed by horizontal drilling ... are not susceptible to migration in the same fashion as found in formations traditionally targeted by vertical drilling." Id . at 813 ; see also Wells, 9 TEX. J. OIL GAS & ENERGY L. at 333-34 ; Kelly Hwa, Note, Hydraulic Fracturing and Forced Pooling Laws: Why Fracking Operators' Use of Decades-Old Laws to Compel Access to Properties Must Be Reexamined , 63 WAYNE L. REV. 105, 121 (2017) (noting the non-migratory nature of shale gas and the minimal risk of drainage from adjoining property in the horizontal drilling context).

With this backdrop in mind, we turn to the leases at issue, in which the parties have expressly agreed on both when the offset provision is triggered and what Murphy's three options are in the event it applies. If Murphy elects to comply with the provision by drilling a well rather than paying additional royalties or releasing acreage, the provision specifically describes when (commencing within 120 days of the triggering well's completion and continuing with reasonable diligence) and where (on the leased acreage to a depth adequate to test the same formation from which the triggering well is producing) Murphy must drill.

2. Unreasonableness of Implied Proximity Requirement

Although the leases' express language includes no proximity requirement for the offset well, Herbst urges us to imply such a restriction. Herbst complains that failing to do so renders the phrase "offset well" meaningless, thereby writing the word "offset" out of the provision entirely. We disagree. The phrase "offset well" undoubtedly has meaning; the pertinent question is what that meaning is. For the reasons discussed below, we hold that the meaning Herbst ascribes-imposing a location or proximity requirement that goes beyond the leases' express language-is an unreasonable interpretation of the language the parties chose. See Exxon Corp. , 348 S.W.3d at 215 (where the lease "expressly defines the duty, we will not impose a more stringent obligation unless it is clear that the parties intended to [do so]").

As noted, Herbst contends an offset well is necessarily one that protects against drainage and that proximity to the draining well is necessary to effectuate that purpose. This is a reasonable premise in the context of vertical drilling, where placement of an offset well is an important factor in minimizing the amount of oil or gas being drained. See Elliff , 210 S.W.2d at 561 (noting the recognized principle that oil and gas found in underground reservoirs "will migrate across property lines towards any low pressure area created by production from the common pool"). But the same principle does not apply in the context of horizontal drilling and hydraulic fracturing in the Eagle Ford Shale.

First, the only locations that matter in the horizontal-drilling context are the locations of the perforated and fractured portions of the horizontal wellbore. A well may be drilled in close proximity to the lease boundary, yet have absolutely no chance of preventing (or causing) drainage depending on the direction of the horizontal wellbore and the placement of the perforations. See Holliday, 44 ST. MARY'S L.J. at 779 (explaining that "horizontal drilling increases the exposure of the perforated (i.e., producing) portion of the wellbore"). Suppose, for example, the Lucas well's surface location was within 467 feet of the lease line, but the horizontal wellbore traveled perpendicular to and away from, rather than parallel to, the lease line. In that case, protecting against drainage would be a logical impossibility. As this hypothetical illustrates, if the parties had intended the offset well to protect against drainage, the provision would presumably have included requirements regarding the direction and placement of the perforated portions of the horizontal wellbore.

The dissent nevertheless insists that incorporating an intent to protect against drainage into the use of the term "offset well" would be in accordance with "decades of the industry's usage." Post at 120. But even leaving aside the ineffectiveness of a proximity requirement in effectuating that intent, discussed above, this conclusion ignores the absence of a significant possibility of drainage occurring in this context in the first instance. It is undisputed that the leases at issue, which govern tracts within the tight Eagle Ford Shale formation, contemplated the use of horizontal drilling and hydraulic fracturing, both of which are necessary to economically recover oil and gas from such formations. Wells, 9 TEX. J. OIL GAS & ENERGY L. at 320. And as noted, commentators recognize the minimal risk of drainage in this context. E.g., id. at 333-34 ("[G]iven the low permeability of the Eagle Ford shale formation, the historic issues of conventional formations-the risk of substantial drainage from neighboring tracts and the risk of not allowing the formation to produce at its maximum efficient recovery rate-would appear to be largely inapposite with unconventional shale formations.").

In light of this context, the court of appeals' holding that Murphy could prevail only by affirmatively demonstrating that the Herbst well was protecting against drainage, despite the absence of a significant possibility that drainage was in fact occurring, is simply not logical. And while Herbst does not argue that Murphy had such a burden, Herbst's contention that the parties intended to presume drainage by the Lucas well, and correspondingly intended to prevent such drainage via the offset well, is similarly not reasonable. Even if it were, as discussed, requiring the offset well to be drilled in close proximity to the lease line would not address the problem.

3. The Only Reasonable Construction

While the leases do not provide a formal definition of the term "offset well," the phrase is nevertheless internally defined by the leases' description of where and to what depth the offset well must be drilled. And these requirements qualify such a well as one that "serves to counterbalance or to compensate for" a triggering well on the adjacent property. Offset , WEBSTER'S THIRD INT'L DICTIONARY 1567 (2002). The fact that the leases specify exactly what is to be done once the offset provision is triggered, and do not mention proximity, is significant. The language of the provision is direct: when triggered, if Murphy elects to respond by drilling a well, it must commence drilling operations within 120 days from the triggering well's completion and must continue drilling with due diligence "to a depth adequate to test the same formation from which the well or wells are producing from [sic] on the adjacent acreage." Murphy was thus required to drill a well in accordance with this specific instruction, and no more.

This makes complete sense if the parties intended to require accelerated drilling when production from a well on an adjacent tract evidenced that the leased tract was also capable of production. While this would not prevent drainage, it would compensate Herbst by counterbalancing against production on the adjacent tract. And this is the only reasonable interpretation of the provision in light of the parties' recognition of the horizontal shale drilling at issue.

In so holding, we recognize that leases executed in other settings-not involving shale plays and hydraulic fracturing from horizontal wellbores-may utilize similar provisions that remain silent as to proximity requirements. But in accordance with our holding in URI , we must account for the circumstances in which these leases were executed. Therefore, we limit our holding to the circumstances at hand, which involve unconventional production in tight shale formations. We express no opinion as to the proper interpretation of similar clauses outside this context.

III. Conclusion

Ultimately, we interpret a lease agreement according to its express language, and we do not read into the lease more stringent obligations than the parties intend. Here, the offset provision contains specific requirements, and Murphy met those requirements. Herbst's reading of the offset provision to contain a proximity requirement constitutes a significant deviation from the language the parties chose and a failure to acknowledge the circumstances in which the leases were executed. Further, it would result in a significant windfall in light of the royalties Herbst is undisputedly collecting based on production from the Herbst well. Accordingly, the trial court properly granted summary judgment in Murphy's favor. We reverse the court of appeals' judgment and reinstate the trial court's judgment as modified to remove the award of appellate attorney's fees.

Justice Johnson filed a dissenting opinion, in which Justice Green, Justice Guzman, and Justice Boyd joined.

This case is about what the parties to contracts-mineral leases-agreed to. It is not about where the perforated portions of horizontal wells are, or engineering distinctions between vertical wells and horizontal wells, or the drainage characteristics of the Eagle Ford Shale formation. There is no indication that such finer points of oil and gas production were within the contemplation of the two sides that negotiated and executed the leases before us. The only evidence outside of the leases themselves that addresses the intent of the parties is the depositions of the Herbsts. The Court sidesteps that evidence by deciding the leases are unambiguous and construing the word "offset" in them as a matter of law. And that is important, because, as discussed below, the depositions indicate that the Herbsts were not negotiating the leases on the basis of engineering or geological principles. They were negotiating on the basis that they wanted their minerals protected from even the possibility of being poached by means of any type of well on adjacent property-whether vertical or horizontal. Nevertheless, the Court discusses subjects such as the direction of horizontal well laterals and whether they run parallel or perpendicular to lease lines, perforations of wells, and geological characteristics of the Eagle Ford Shale. It does so in trying to explain on behalf of Murphy why the parties who were involved in negotiating and executing the leases-one of whom was not Murphy-could not have intended for the phrase "offset well" as used in the leases to mean precisely what it meant for decades before, and at the time of, the leases' executions.

The Court's construction of the leases and discussions of drainage characteristics of the Eagle Ford Shale are, to a significant degree, based on treatises written years after the leases were executed. The Court also focuses on the fact that the well triggering Murphy's requirement to drill an offset well was producing from the Eagle Ford Shale and that wells producing from that formation are horizontal wells. The Court discounts the fact that the leases are not limited to the Eagle Ford Shale, but instead encompass all the minerals under the lease acreage, and that the leases do not limit themselves to horizontal wells, but instead also specifically contemplate and reference vertical wells.

In construing the offset well provisions of the leases, the Court says that (1) the entire lease must be considered in an effort to harmonize and give effect to all its provisions so that none will be rendered meaningless, and (2) the lease is to be construed in light of the circumstances present when it was entered into. Ante at 108-09. I agree. But the Court fails to adhere to those principles in reaching its decision. I respectfully dissent.

I. Background

The oil and gas leases (Leases) that Alvin M. Barrett & Associates, Inc. (Barrett), the predecessor-in-interest of Murphy Exploration and Production Company, entered into with Shirley Mae Herbst Adams and William Albert Herbst (collectively, the Herbsts ) each contain the following paragraph:

25.) It is hereby specifically agreed and stipulated that in the event a well is completed as a producer of oil and/or gas on land adjacent and contiguous to the leased premises, and within 467 feet of the premises covered by this lease, that Lessee herein is hereby obligated to, within 120 days after the completion date of the well or wells on the adjacent acreage, as follows:

As the Court notes, the parties do not dispute that the Lucas A # 1H horizontal well (Lucas, or Lucas well) was completed in the Eagle Ford Shale formation on a tract "adjacent and contiguous" to the leased premises and is "a producer of oil and/or gas." The parties agree that the Lucas well triggered Murphy's obligations under the offset well clause. Murphy claims that it complied with the clause by drilling the Herbst Unit B1H well (Herbst, or Herbst well), a horizontal well whose lateral runs approximately parallel to that of the Lucas's lateral but over 2,000 feet from it. In the trial court and court of appeals, the Herbsts maintained that the Leases unambiguously required Murphy to locate an offset well as close as reasonably possible or as close as regulations permit to the triggering well and that as a matter of law, the Herbst did not fulfill this requirement. The court of appeals held that Murphy failed to prove as a matter of law that the Herbst met the requirements of the offset clause, so Murphy was not entitled to summary judgment. 497 S.W.3d 510, 516-17 (Tex. App.-San Antonio 2016). The court concluded that an offset well protects against drainage, meaning Murphy's summary judgment burden was to conclusively prove that the Herbst was protecting from drainage by the Lucas. Id. at 516. Because Murphy did not do so, it was not entitled to summary judgment. Here, the Herbsts seek only to have the judgment of the court of appeals affirmed. For the reasons expressed below, which differ somewhat from those of the court of appeals, I would do so.

II. Standard of Review and Law

Mineral leases are contracts and are interpreted using the same rules that are applied in interpreting contracts. Tittizer v. Union Gas Corp. , 171 S.W.3d 857, 860 (Tex. 2005). Thus, in construing an oil and gas lease, our task is to "seek the intention of the parties as that intention is expressed in the lease." Sun Oil Co. (Del.) v. Madeley , 626 S.W.2d 726, 727-28 (Tex. 1981) ; see also Italian Cowboy Partners, Ltd. v. Prudential Ins. Co. of Am. , 341 S.W.3d 323, 333 (Tex. 2011). Summary judgment as to a contract interpretation issue is proper only if the parties' intent, as expressed in the language of the contract, has been conclusively established. See Plains Expl. & Prod. Co. v. Torch Energy Advisors Inc. , 473 S.W.3d 296, 305 (Tex. 2015).

If a contract contains an ambiguity, "the granting of a motion for summary judgment is improper because the interpretation of the instrument becomes a fact issue." Coker v. Coker , 650 S.W.2d 391, 394 (Tex. 1983). If "the contract is subject to two or more reasonable interpretations after applying the pertinent rules of construction, the contract is ambiguous." Columbia Gas Transmission Corp. v. New Ulm Gas, Ltd. , 940 S.W.2d 587, 589 (Tex. 1996). "Whether a contract is ambiguous is a question of law, subject to de novo review." Bowden v. Phillips Petroleum Co. , 247 S.W.3d 690, 705 (Tex. 2008). A contract may be ambiguous even though the parties agree it is not because ambiguity is a question of law for courts to decide. Progressive Cty. Mut. Ins. Co. v. Kelley , 284 S.W.3d 805, 808 (Tex. 2009). In determining whether a contract is ambiguous, the contract is to be examined as a whole in light of the circumstances present when it was entered into. Nat'l Union Fire Ins. Co. v. CBI Indus. , 907 S.W.2d 517, 520 (Tex. 1995) ; see also First Bank v. Brumitt , 519 S.W.3d 95, 109-10 (Tex. 2017) (explaining that courts may consider the context in which an agreement was made in determining whether it is ambiguous). As part of this inquiry, the entire writing is to be considered in an effort to harmonize and give effect to all its provisions so that none will be rendered meaningless. Seagull Energy E & P, Inc. v. Eland Energy, Inc. , 207 S.W.3d 342, 345 (Tex. 2006) (quoting Coker , 650 S.W.2d at 393 ). Further, terms are to be considered as having been given "their plain, ordinary, and generally accepted meaning unless the instrument shows that the parties used them in a technical or different sense." Heritage Res., Inc. v. NationsBank , 939 S.W.2d 118, 121 (Tex. 1996). When considering motions for summary judgment, courts are to indulge every reasonable inference and resolve any doubts in favor of the nonmovant. Kachina Pipeline Co. v. Lillis , 471 S.W.3d 445, 449 (Tex. 2015).

III. Discussion

A. Language of the Leases

As with any contract, the Leases must be read according to the language the parties used, without adding to or taking away from it. Heritage Res., Inc. , 939 S.W.2d at 121 ("We presume that the parties to a contract intend every clause to have some effect. We give terms their plain, ordinary, and generally accepted meaning unless the instrument shows that the parties used them in a technical or difference sense." (citations omitted) ). The Leases were executed in 2009, and Murphy-an entity that does not claim to have been part of or have had any connection with the lease negotiations-argued in the lower courts and continues to argue here that the offset well provision was drafted with horizontal wells in mind. Without further explication, the Court slips past the lack of evidence of that position by saying that the Herbsts "[do] not dispute that [the Leases] were drafted with horizontal shale drilling in mind." Ante at 110. The Court recognizes the proximity requirement associated with the traditional definition of offset well and states, without respect to the fact that the Leases must be construed as intended by the Herbsts and Barrett, who negotiated them, that "[t]his is a reasonable premise in the context of vertical drilling, where placement of an offset well is an important factor in minimizing the amount of oil or gas being drained. But the same principle does not apply in the context of horizontal drilling and hydraulic fracturing in the Eagle Ford Shale." Ante at 112 (citation omitted).

There are two problems with the Court's position. First, the Court simply decides-without any indication in the Leases-that the Leases must have been based on what the Court decides would have been a "reasonable premise" or principle, without regard to what the Herbsts and Barrett actually intended when they entered into the Leases. Second, the Court badly shortchanges the Herbsts' position. The Herbsts point out that the Leases expressly contemplate both vertical and horizontal drilling, impose the offset well obligation regardless of the type of well involved, and authorize no special treatment with respect to either type of well. That is unquestionably the situation. For example, paragraph 23.) of the Leases has two subparagraphs. One is entitled and references "Vertical Wells," while the other is entitled and references "Horizontal Wells." Thus, the offset well provision must be interpreted in light of the parties' intent, as expressed in the Leases, that the Leases encompass and address all types of wells, not just horizontal wells. Moreover, as amicus curiae Texas Land and Mineral Owners Association (TLMOA) observes and the Court fails to acknowledge, the Leases grant Murphy the right to produce all minerals under the Herbsts' land, not just those found in the Eagle Ford Shale. According to the affidavit of Murphy's expert John C. McBeath, the Eagle Ford Shale "lies directly below the Austin Chalk formation and has long been recognized as the hydrocarbon source rock for the Austin Chalk," and lies directly above the Buda Limestone formation. The Leases thus entitle Murphy to produce from either of those two formations if they lie under the Herbsts' land, which has not been established either way.

Although the Court expressly limits its holding to "shale plays and hydraulic fracturing from horizontal wellbores," Ante at 113, the Court's reasoning implies that had the Lucas been a vertical well drilled into the Austin Chalk, for example, and had Anadarko drilled a vertical well into the same formation and location as the Herbst well, then the Herbst would not be an offset well under the offset clause. Ante at 109-10. But the offset clause makes no distinction between wells drilled into any particular formation, nor does it treat vertical or horizontal wells in a disparate manner. There is no indication in the Leases that the Herbsts and Barrett, who negotiated them, intended the clause to mean one thing for vertical wells and another for horizontal wells.

The Court similarly errs in considering the proximity factor of an offset well in the context of horizontal drilling and hydraulic fracturing. The Court suggests that in horizontal drilling, the only locations that matter are the locations of the perforated and fractured portions of the horizontal wellbore. Ante at 112. According to the Court, horizontal wells only drain from the perforated portions, so although a horizontal well's surface location may be within the offset distance, its perforations may not be. Ante at 112. The Court provides a hypothetical in which a horizontal well runs perpendicular to the lease line, not parallel to it, meaning protecting against drainage caused by the well would be a "logical impossibility." Ante at 112. The Court thus concludes that if the parties intended protection against drainage, the provision would have "included requirements regarding the direction and placement of the perforated portions of the horizontal wellbore." Ante at 112. This may have perhaps been a better way to draft the offset well requirement, but it is not what the parties to the Leases agreed. If the Herbsts and Barrett had been experts in drilling wells and the various aspects of horizontal wells, as Murphy apparently is, they may have drafted the Leases differently. But there is no evidence in the record about Barrett, even if the Court would consider it, and the only evidence about the Herbsts is in their depositions, which the Court avoids considering by interpreting the Leases as a matter of law. So the Court's entire discussion is neither linked to language of the Leases, nor any evidence in this record-even if the Court could consider evidence, given its position that the Leases must be construed as a matter of law. Beyond that, its hypothetical brings into this case information that the record does not show was a consideration for either the Herbsts or Barrett in their negotiating and executing the Leases.

This case is about what the parties agreed to, not what a court can suggest in hindsight that they should or could have agreed to. The Herbsts and Barrett included the term offset well in relation to any and all wells covered by the Leases-both vertical and horizontal wells drilled into the Eagle Ford Shale or any other formation.

The Leases must be read without adding to or taking away from their language absent some necessity to do so to avoid an irreconcilable conflict. See Heritage Res., Inc. , 939 S.W.2d at 121 ; see also U.S. Metals, Inc. v. Liberty Mut. Grp., Inc. , 490 S.W.3d 20, 23-24 (Tex. 2015) ("An interpretation that gives each word meaning is preferable to one that renders one surplusage."). The Court states, "While the leases do not provide a formal definition of the term 'offset well,' the phrase is nevertheless internally defined by the leases' description of where and to what depth the offset well must be drilled. And these requirements qualify such a well as one that 'serves to counterbalance or to compensate for' a triggering well on the adjacent property." Ante at 113 (footnote omitted) (citing Offset , WEBSTER'S THIRD INT'L DICTIONARY 1567 (2002) ). But that interpretation reads the word offset out of the Leases even though offset and its generally accepted meaning in the industry when the Leases were executed does not conflict with any other part of the Leases, much less irreconcilably conflict. Under the Court's interpretation, what the parties and the Court refer to as an offset provision imposes no more obligations on the lessee than would the same Leases without the word offset:

(2) pay the Lessor royalties as provided for in this lease as if an equivalent amount of production of oil and/or gas were being obtained from the

off-set

location on these leased premises as that which is being produced from the adjacent well or wells; or

Omitting the word offset makes the Leases read as Murphy contends they do, and as the Court decides they do: if the offset provision is triggered, Murphy simply had to drill a well anywhere on the Leases to the appropriate depth. Murphy argues that paragraph 25.)(1) would have said "direct offset" if the parties intended it to require wells to be drilled close to wells completed on adjacent lands. But the Leases make perfect sense as they are written without, in hindsight and in the context of litigation, adding the word "direct." Thus, offset as used in paragraph 25.), and which appears nowhere else in the Leases, unquestionably was intended to mean something.

The Court's treatment of the word offset in the Leases ignores the consistent, longstanding industry use of the word in regard to wells, as is noted below. See URI, Inc. v. Kleberg County , 543 S.W.3d 755, 768 (Tex. 2018) ("[T]rade usage can illuminate the meaning of contract language because 'the meaning to which a certain term or phrase is most reasonably susceptible is the one which [is] so regularly observed in place, vocation, trade or industry so "as to justify an expectation that it will be observed with respect to a particular agreement ." ' " (emphasis added) (quoting Nat'l Union Fire Ins. Co. , 907 S.W.2d at 521 n.6 ) ). Nor does the Court's treatment of the phrase offset well as an internally defined term that does not import any of the phrase's well-established meaning in the industry account for the term's use by these parties. Similarly, Murphy's calling paragraph 25.) a "free well" clause and treating offset as only a meaningless label does not account for the use of the word in the context of the oil and gas industry and the world of mineral leases.

Under the interpretations of paragraph 25.) advanced by both the Herbsts and Murphy, the Herbsts were entitled to have a well drilled on the Herbsts' land. The question is where. To answer this question, the court of appeals turned to the industry meaning of offset well in addition to looking to case law. It concluded that the Leases unambiguously imposed an obligation on Murphy to protect the Herbsts' land from drainage, and because Murphy failed to prove conclusively it had done so, the court of appeals reversed the trial court's judgment. Murphy argues that both the Herbsts' and the court of appeals' positions render other language in the Leases surplusage. That is, if offset well means a well drilled within a reasonable distance from the triggering well on adjacent land as a counterbalance to the triggering well and its drainage, then there was no need to specify in the lease that the offset well was to be drilled "with due diligence to a depth adequate to test the same formation [as the triggering well]." But as amicus curiae TLMOA points out, the language Murphy calls surplusage actually is not. It serves to re-incorporate a portion of the reasonably prudent operator standard of the implied covenant to protect the lease by protecting from drainage in light of the express offset well requirement in the Leases. See Magnolia Petroleum Co. v. Page , 141 S.W.2d 691, 693 (Tex. Civ. App.-San Antonio 1940, writ ref'd).

Murphy's response to TLMOA's argument is that if the term offset well imposes an obligation to protect against drainage (as the court of appeals held and the Herbsts imply), it would be "facially absurd" if a well "shoddily drilled in a different formation" could satisfy the lessee's obligations. However, Murphy also argues that an express offset well provision supersedes and supplants the implied covenant to protect against drainage, which includes the reasonably prudent operator standard. I do not completely disagree. But if an express clause supersedes the reasonably prudent operator standard, then it would necessitate lessors specifying how an offset well must be drilled, which is a subject separate and apart from what an offset well is. If lessors failed to do so, there would be nothing (i.e., the reasonably prudent operator standard) to prevent "facially absurd" results. But expressly incorporating the entire reasonably prudent operator standard anywhere in the clause could have brought with it the elements of a cause of action for the breach of the implied covenant. See Mzyk v. Murphy Expl. & Prod. Co.-USA , No. 04-15-00677-CV, 2017 WL 2797479, at *4 (Tex. App.-San Antonio June 28, 2017, no pet.) (holding that an offset clause that included a "deemed drainage provision" but also later incorporated the reasonably prudent operator standard required the lessor to prove the triggering well was causing drainage). So, as TLMOA points out, the Leases instead include only portions of the implied covenant. Furthermore, even if Murphy were correct that courts would not allow "facially absurd" results, it was not unreasonable for the Herbsts to hedge their bets by including the language in the Leases to avoid the potential for litigation regarding the adequacy of the manner in which the offset well was drilled. Murphy's argument thus ignores the reason for the offset well provision.

The Court also fails to account for another portion of the offset well clause supporting the notion that use of the word offset imposes a proximity requirement. When the clause was triggered, Murphy had three options, one of which was to

pay the Lessor royalties as provided for in this lease as if an equivalent amount of production of oil and/or gas were being obtained from the off-set location on these leased premises as that which is being produced from the adjacent well or wells.

(Emphasis added). That the clause references "the off-set location" suggests that the parties did not intend for an offset well to be drilled in a random location. Instead, the parties appear to have contemplated a particular location. Given the commonly understood meaning of offset well as discussed below, that location was certainly not where Murphy drilled the Herbst well, which was almost as far from the triggering well as possible.

The question remains, "Where?" And the answer must be, "In a location that a reasonably prudent operator would consider sufficient to protect from potential drainage." Otherwise, the word offset in the provision has no meaning. And while the lease requirement that the offset well be drilled to a depth adequate to test the formation from which the triggering well is producing might seem to be surplusage under that interpretation, if the choice regarding interpreting these Leases is between jettisoning decades of the industry's usage as to what offset well means, or accepting the requirement of drilling to a depth adequate to test the formation being produced by the triggering well as being surplusage, the better choice by far is the latter.

Murphy argues, and the Court apparently agrees, that by reading offset to impose an obligation to protect against drainage, the Hersbsts and the court of appeals are augmenting the Leases by adding to them. Ante at 111 ("[W]here the lease 'expressly defines the duty, we will not impose a more stringent obligation unless it is clear that the parties intended to [do so].' " (quoting Exxon Corp. v. Emerald Oil & Gas Co. , 348 S.W.3d 194, 215 (Tex. 2011) ) ). Accepting Murphy's argument, the Court concludes that the clause's only requirements for an offset well are that it be drilled "on the lease acreage" and "to a depth adequate to test the same formation" from which the triggering well was producing. Ante at 110. According to the Court, the clause is silent with respect to any duty to protect against drainage or a proximity requirement; thus, the imposition of any such obligations would be altering the terms of the Leases. I disagree. But as discussed elsewhere, courts as well as the oil and gas industry have long understood the term offset well to mean a well that protects from either actual or potential drainage. And we would not be adding language to the Leases by treating the term as meaning what it so plainly meant in 2009, when the Leases were executed, and had meant long before then in the context of oil and gas leases.

Thus, Murphy's interpretation either reads words out of the Leases, renders provisions surplusage, or adds to their language; the Herbsts' does not, except for the possibility noted just above. I would reject Murphy's interpretation as unreasonable. See U.S. Metals, Inc. , 490 S.W.3d at 23-24 ("An interpretation that gives each word meaning is preferable to one that renders one surplusage."); J.M. Davidson, Inc. v. Webster , 128 S.W.3d 223, 229 (Tex. 2003) ("[In determining whether a contract is ambiguous,] we must examine and consider the entire writing in an effort to harmonize and give effect to all of the provisions of the contract so that none will be rendered meaningless."); Am. Mfrs. Mut. Ins. Co. v. Schaefer , 124 S.W.3d 154, 157 (Tex. 2003) ("[W]e must give effect to all contractual provisions so that none will be rendered meaningless.").

B. Context of Execution of the Leases

In interpreting the Leases, we may consider the circumstances present in August 2009, when they were executed. See Nat'l Union Fire Ins. Co. , 907 S.W.2d at 520. Those circumstances include the meaning commonly applied by the industry and courts to offset well language prior to and contemporaneously with the execution of the Leases. See Heritage Res., Inc. , 939 S.W.2d at 121-22. Looking to those circumstances, it is clear that long before and at the time the Leases were executed, the traditional and widespread industry meaning of offset well was a well that protected the leasehold from being drained of its minerals. See, e.g. , Offset Well , BALLENTINE'S LAW DICTIONARY (3d ed. 1969) (defining "offset well" as "[a]n oil well dug for the specific purpose of preventing drainage of oil to adjoining property"); RICHARD LEROY BENOIT , CYCLOPEDIA OF OIL AND GAS FORMS §§ 168-70, at 205-07 (1926) (discussing offset well clauses and implying they are related to protection from drainage); DAN S. BOYD , THE STATE OF TEXAS , GOVERNOR'S ENERGY ADVISORY COUNCIL , LEGAL ASPECTS OF STATE-OWNED OIL AND GAS ENERGY RESOURCES 21-22 (1974) (discussing the Relinquishment Act's offset well clause and noting state leases expressly require the drilling of "offset wells" when drainage from nearby wells is actually occurring); EARL A. BROWN , THE LAW OF OIL AND GAS LEASES § 16.02(5)(D), at 317 (1958) (noting that the implied covenant of "the lessee to protect the leased premises against drainage from wells on adjoining premises by drilling offset wells" can be superseded by an express clause); GRAYSON CECIL FOX , OIL AND GAS DRILLING FUNDS : A PRIMER FOR ATTORNEYS AND INVESTORS

§ 2.22(c), at 15-16 (1983) (observing that leases can provide for express covenants, "such as the covenant to offset if a well is brought in on adjacent property"); R.L. HANKINSON & R.L. HANKINSON JR. , LANDMAN'S ENCYCLOPEDIA § 119, at 329 (2d ed. 1981) (containing a form of an "offset obligation waiver clause," which waives a lessee's express or implied obligations to drill "an offset or protection well" and waives the lessor's "claims or demands for damages occasioned by drainage of the lease premises" by an adjacent well); RICHARD W. HEMINGWAY , THE LAW OF OIL AND GAS § 8.6, at 565 (3d ed. 1991) (referring to an "express offset clause" as a clause "relating to the obligation of the lessee to drill offset or protection wells" and noting such clauses can supersede the implied covenant); EUGENE O.

LOWE, OIL AND GAS LAW 331 (4th ed. 2003) (stating that for a claim for a breach of the implied covenant to protect against drainage, a lessor must show substantial drainage and "a probability that an offset well would be profitable"); MAURICE H. MERRILL , COVENANTS IMPLIED IN OIL AND GAS LEASES § 94, at 234 (2d ed. 1940) ("If producing wells are drilled upon adjoining lands within draining distance of the line, it behooves the owner of the land to counteract their influence by 'offset' wells upon his own premises."); 1 ERNEST E. SMITH & JACQUELINE LANG WEAVER , TEXAS LAW OF OIL AND GAS § 5.3(B)(2), at 267-68 (1989) (noting that offset clauses "require the lessee to drill an offset if a well on other land is drilled within a specified maximum distance from the leased premises"); SAMUEL S. WYER , U.S. NAT'L MUSEUM, BULLETIN 102, PT. 7, NATURAL GAS: ITS PRODUCTION , SERVICE , AND CONSERVATION 55-56 (1918) ("The primary feature to be borne in mind is that the offset well is drilled for purposes of protection, and that this is more important than hard and fast rules regarding exact location."); George A. Bibikos & Jeffrey C. King, A Primer on Oil and Gas Law in the Marcellus Shale States , 4 TEX. J. OIL GAS & ENERGY L. 155, 164 n.36 (2009) ("An offset well is defined as 'a well drilled on one tract of land to prevent the drainage of oil or gas to an adjoining tract of land, on which a well is being drilled or is already in production.' " (quoting 1 HOWARD R. WILLIAMS & CHARLES J. MEYERS , OIL AND GAS LAW 684 (2008) ) ); see also JOSEPH SHADE , PRIMER ON THE TEXAS LAW OF OIL AND GAS , app. 10 (rev. 4th ed. 2012) ("Offset well. A well drilled on one tract of land to prevent the drainage of oil to an adjoining tract of land, on which a well is being drilled or is already in production."); accord TEX. NAT. RES. CODE § 52.173 (containing a statutory offset well clause with which parties leasing the mineral interests to state land must comply and stating that an "offset well shall be drilled to a depth and the means shall be employed which may be necessary to prevent undue drainage of oil or gas from beneath the state land").

Additionally, when the Leases were executed in 2009, this Court had for years referenced an offset well as a well located and drilled to protect against drainage. See, e.g. , Coastal Oil & Gas Corp. v. Garza Energy Tr. , 268 S.W.3d 1, 14 (Tex. 2008) (noting that landowners have recourse for drainage-drilling an offset well to protect against it); Amoco Prod. Co. v. Alexander , 622 S.W.2d 563, 567 (Tex. 1981) (acknowledging that local drainage "can be prevented by drilling offset wells"); Shell Oil Co. v. Stansbury , 410 S.W.2d 187, 188 (Tex. 1966) (holding that an offset well clause required the lessee to drill an "offset well" in response to drainage);

Commonwealth of Massachusetts v. Davis , 168 S.W.2d 216, 223 (Tex. 1942) (discussing an offset well clause); Brown v. Humble Oil & Ref. Co. , 83 S.W.2d 935, 940 (Tex. 1935) (noting that at common law, an "adjoining landowner cannot complain if wells are drilled near his boundary line" and that the landowner can protect himself by drilling "offset wells"); Tex. Pac. Coal & Oil Co. v. Barker , 6 S.W.2d 1031, 1036 (Tex. 1928) (indicating that "offset well" refers to a well drilled in response to a producing well on an adjacent tract in order to protect against drainage).

However, Murphy maintains that in light of the "relatively modest drainage," as Murphy's expert described it, occurring in the Eagle Ford Shale, no reasonable person in 2009 would have ascribed the traditional meaning of offset well to this offset well clause. The Court, while acknowledging that we have "recognized that drilling an offset well can be a method of protecting against drainage," similarly uses the attributes of the Eagle Ford Shale to buttress its conclusion that Murphy's is the only reasonable interpretation. Ante at 110. I disagree with both the conclusion and the use of the evidence supporting it.

First, the Court seems to criticize my using a string cite of "authorities that predate the advent of the type of drilling at issue here." Ante at 112. Ordinarily, such cites might be relegated to a footnote. But in this instance, the cites are a substantive reflection of circumstances both preexisting the Leases and at the time the Leases were executed. Further, if a source did not exist at the time of or before execution of the Leases, then it cannot fairly be included in the circumstances surrounding their execution and does not shed any light on the parties' intent. The Court and Murphy effectively take the position that the advent of horizontal drilling has robbed offset well of its long-established meaning. But even a cursory survey of more current sources than those I cite above showing the circumstances at the time the Leases were executed reveals this is not the case. See, e.g. , 55 TEX. JUR. 3D Oil and Gas § 217 (2018) ("Offset drilling may be used as a guard against drainage of oil and gas from under one owner's land caused by the withdrawal of oil and gas by an adjoining landowner. An obligation to drill offset wells may rest on the lessee, either by express provision of the lease or by implication."); NORMAN HYNE , DICTIONARY OF PETROLEUM EXPLORATION , DRILLING, & PRODUCTION 352 (2d ed. 2014) (defining "offset well" as "a well drilled on the next adjacent drilling and spacing unit to an existing well to compensate for and/or prevent drainage by that well"); R.D. LAGENKAMP , HANDBOOK OF OIL INDUSTRY TERMS & PHRASES 344 (6th ed. 2014) (defining "offset well" as "[a] well drilled on one tract of land to prevent the drainage of oil or gas to an adjoining tract where a well is being drilled or is already producing"); LEVONNE LOUIE , MINERAL LAND RIGHTS: WHAT YOU NEED TO KNOW ch. 6 (2014) ("The offset well clause provides a mechanism whereby landowners can protect themselves from drainage if a well is drilled on a DSU beside their land (the offset section)."); 2 NANCY SAINT-PAUL, SUMMERS OIL AND GAS § 17:7, at 511 (rev. 3d ed. 2016) (stating, in a section titled "Express covenant to drill offset wells," that "the modern oil and gas lease often contains an express covenant obligating the lessee to protect the leased land from drainage by drilling wells offsetting protective wells on adjacent lands"); JOSEPH SHADE & RONNIE BLACKWELL , PRIMER ON THE TEXAS LAW OF OIL & GAS app. A (5th ed. 2014) (defining offset well as a "well drilled on one tract of land to prevent the drainage of oil to an adjoining tract of land, on which a well is being drilled or is already in production"); 8 Offset Well , HOWARD R. WILLIAMS & CHARLES J. MEYERS , OIL AND GAS LAW 684 (LexisNexis Matthew Bender 2017) ("[An offset well is a] well drilled on one tract of land to prevent the drainage of oil or gas to an adjoining tract of land, on which a well is being drilled or is already in production."). Recent cases from this Court also demonstrate our understanding of the term by using it without seeing the need to provide any explanation of its meaning. See, e.g. , Hooks v. Samson Lone Star, Ltd. , 457 S.W.3d 52, 67-68 (Tex. 2015) ; Lesley v. Veterans Land Bd. , 352 S.W.3d 479, 488 (Tex. 2011).

In short, before, at the time of, and even after the Leases were executed, offset well meant and continues to mean a well that protects a lease from the possibility of drainage.
