of De Witt County, Texas.

MEMORANDUM OPINION

Before Chief Justice Valdez and Justices Rodriguez and Longoria

Memorandum Opinion by Chief Justice Valdez
2

This case concerns ownership of a non-participating royalty interest1(NPRI) in the 

gross production of oil and gas covering a tract of land located in Dewitt County, Texas. 

On competing motions for summary judgment, the trial court entered a declaratory 

judgment stating that the NPRI is owned by the appellees/cross-appellants Ralph Wade 

Koopmann, Karen Marie Koenig, and Lorene H. Koopmann (the Koopmanns) and not 

appellant Lois Strieber, individually and as executrix of the state of Jerry Strieber. Also 

on summary judgment, the trial court dismissed certain claims brought by the Koopmanns 

against appellants/cross-appellees Burlington Resources Oil & Gas Co., L.P. (Burlington) 

and ConocoPhillips Company (ConocoPhillips). We affirm in part and reverse and 

remand in part.

I. FACTUAL BACKGROUND

By warranty deed dated December 27, 1996, Strieber conveyed the surface and 

mineral estate of a 120-acre tract of land to the Koopmanns. As per the deed, Strieber

reserved for herself the NPRI at issue for a period of fifteen years, or until December 27, 

2011, and for “as long thereafter as there is production [of oil, gas, or minerals from the 

land] in paying or commercial quantities.” The deed also contained a “savings clause,” 

allowing for Strieber’s NPRI to be preserved beyond December 27, 2011 without actually 

producing oil, gas, or minerals from the land. Specifically, the deed’s savings clause 

provided that: 

[I]f any oil, gas, or mineral or mining lease covering [the Koopmanns’ land] 

is maintained in force and effect by payment of shut-in royalties or any other 

similar payments made to [the Koopmanns] in lieu of actual production while 

 

1 A nonparticipating royalty interest, or NPRI for short, is an interest in the gross production of oil, 

gas, and other minerals below the surface of land. See Plainsman Trading Co. v. Crews, 898 S.W.2d 786, 

789–90 (Tex. 1995). The owner of the NPRI may receive royalties from the gross production of oil, gas, 

and other minerals but may not participate in the execution of any oil, gas, and mineral lease. Id. 
3

there is located on [the Koopmanns’ land] a well or mine capable of 

producing oil, gas, or other minerals in paying or commercial quantities but 

shut-in for lack of market or any other reason, then for purposes of 

determining [whether Strieber’s NPRI continues beyond December 27, 

2011,] it will be considered that production in paying or commercial 

quantities is being obtained from the [Koopmanns’ land].

In 2007, the Koopmanns entered into a three-year lease with Burlington, an oil and 

gas company, for the purpose oil and gas exploration and development under their land. 

In 2010, with a few months remaining on the three-year lease, ConocoPhillips, 

Burlington’s parent company, paid the Koopmanns $24,000 to extend Burlington’s lease 

for an additional two years, or until October 2012. 

By August 2011, Strieber’s initial fifteen-year NPRI term under the deed was four 

months away from terminating in December 2011, and Burlington had not been able to 

produce oil and gas from the Koopmanns’ land. As an incentive to accelerate the drilling 

process, Strieber offered Burlington a 60% interest in her NPRI, which Burlington 

accepted. As such, Strieber and Burlington then owed 40% and 60% of the NPRI, 

respectively. 

Thereafter, Burlington identified a well site on the Koopmanns’ land and began a 

process called “hydraulic fracturing” to complete the drilling of a well. On December 7, 

2011, ConocoPhillips, on behalf of Burlington, sent a letter informing the Koopmanns that 

a well was anticipated to begin producing oil and gas in the first quarter of 2012. Noting 

the deed’s savings clause, ConocoPhillips enclosed a shut-in royalty payment, which, 

according to the letter, was being tendered to the Koompanns to “ensure that all parties' 

interest, if any, in the well [was] maintained.” However, the Koopmanns promptly returned 

this shut-in royalty payment to ConocoPhillips. 
4

The summary judgment evidence is undisputed that no well actually produced oil, 

gas, or minerals from the land until February 2012, which is some two months after 

Strieber’s initial fifteen-year NPRI term ended on December 27, 2011. Although there 

was no production by December 27, 2011, Burlington and ConocoPhillips’ expert, Joseph 

Rhodes, determined that the well was at least capable of producing as early as December 

16, 2011—thus implicating the savings clause. The Koopmanns, on the other hand, 

sponsored their own expert, Peter Huddleston, who disagreed with Rhodes’ conclusion 

that the well was capable of producing before December 27, 2011—thus negating the 

savings clause. All royalties attributable to the NPRI have been withheld from the 

Koopmanns since the well began producing. 

II. PROCEDURAL BACKGROUND 

The Koopmanns brought a declaratory action against Strieber, Burlington, and 

ConocoPhillips to be declared the owners of the NPRI. The Koopmanns also brought 

several non-declaratory claims against Burlington and ConocoPhillips for withholding 

royalties on the NPRI and for tendering a shut-in royalty payment on December 7, 2011.2 

At an early juncture in the proceedings below, the litigation leading to this appeal fractured 

along two major fault lines; a first cluster of litigation related to the Koopmanns’ request 

for a declaratory judgment concerning ownership of the NPRI, and a second involved 

litigation relating to the Koopmanns’ non-declaratory claims against Burlington and 

ConocoPhillips. 

 

2 With the Koopmanns seeking a declaratory judgment that they owned the NPRI, Strieber brought 

her own cross-claim against Burlington and ConocoPhillips for breach of contract. Strieber asserted that if 

her NPRI was found to have terminated, then Burlington and ConocoPhillips breached an alleged oral 

agreement in 2011 when they failed to secure a producing well by December 27, 2011, as allegedly 

promised.
5

A. Litigation Relating to the Koopmanns’ Request for Declaratory Judgment 

Concerning the first cluster of litigation, the Koopmanns sought a declaration from 

the trial court that they owned the NPRI as of December 27, 2011. In response to the 

Koopmanns’ declaratory action, Strieber, Burlington, and ConocoPhillips moved for 

summary judgment to have the trial court declare that the NPRI remained in Strieber. 

They contended, among other things, that Strieber’s reservation of the NPRI for fifteen 

years, and for as long thereafter as there is production, created a future interest in the 

Koopmanns that violates the rule against perpetuities. They reasoned that because the 

Koopmanns’ future interest is void under the rule against perpetuities, the NPRI stayed 

with Strieber. In the alternative, they asserted that the deed’s saving clause applies to 

preserve Strieber’s NPRI beyond December 27, 2011 even without actual production. 

In a competing motion, the Koopmanns moved for summary judgment to have the 

trial court declare that they own the NPRI. The Koopmanns argued that the savings 

clause did not apply to preserve Strieber’s interest in the NPRI beyond December 27, 

2011, and the rule against perpetuities did not apply to void the NPRI. Agreeing with the 

Koopmanns, the trial court entered a summary judgment declaring that: 

1. As of December 27, 2011, there were no wells actually producing in paying 

or commercial quantities;

2. The NPRI was null and void;

3. Strieber’s and Burlington’s right to the NPRI terminated; and

4. The Koopmanns were entitled to the full amount of any royalty payments 

due under the NPRI.

Although the trial court granted a declaratory judgment in favor of the Koopmanns, 

it did not award them interest on unpaid royalties attributable to the NPRI. 
6

B. Litigation Relating to the Koopmanns’ Non-Declaratory Claims against 

Burlington and ConocoPhillips

Concerning the second cluster of litigation, the Koopmanns brought claims against 

Burlington and ConocoPhillips under contract, quasi-contract, and tort theories. The 

relevant non-declaratory claims include: (1) breach of contract, (2) unjust 

enrichment/money had and received,3(3) conversion, (4) negligence, and (5) negligence 

per se. Specifically, the Koopmanns alleged the following: 

1. Burlington withheld royalties attributable to the NPRI from the 

Koopmanns in breach of their lease agreement [i.e., breach of contract]. 

2. ConocoPhillips, though not a signatory to the lease agreement, unjustly 

enriched itself by receiving royalties owed to the Koopmanns [i.e., unjust 

enrichment/money had and received].

3. Burlington and ConocoPhillips converted royalties legally owned by and 

payable to the Koopmanns [i.e., conversion]. 

4. Burlington and ConocoPhillips were negligent in the performance of the 

lease [i.e., negligence]. 

5. Burlington and ConocoPhillips were negligent per se in the performance 

of the lease by violating section 91.402 of the Texas Natural Resources 

Code [i.e., negligence per se]. 

1. Burlington and ConocoPhillips Move to Dismiss the Koopmanns’ NonDeclaratory Claims Under Texas Rule of Civil Procedure 91a. 

Seeking early dismissal of the above-mentioned claims, Burlington and 

ConocoPhillips filed a motion to dismiss pursuant to Texas Rule of Civil Procedure 91a. 

See TEX. R. CIV. P. 91a.3. In support of their motion to dismiss, Burlington and 

ConocoPhillips asserted that all of the Koopmanns’ claims were barred as a matter of law 

 

3 Money had and received is an equitable doctrine to prevent unjust enrichment. See Amoco Prod. 

Co. v. Smith, 946 S.W.2d 162, 164 (Tex. App.—El Paso 1997, no writ). For purposes of our discussion, 

our analysis addressing the unjust enrichment claim applies equally to the claim for money had and 

received. 
7

under section 91.402(b) of the Texas Natural Resources Code because ownership of the 

NPRI was in dispute. See TEX. NAT. RES. CODE ANN. § 91.402(b) (West, Westlaw through 

2015 R.S.). Aside from the natural resources code, Burlington and ConocoPhillips also 

sought dismissal of the Koopmanns negligence claims under the “economic loss rule.” 

After considering these arguments, the trial court denied the motion to dismiss and 

awarded attorney’s fees to the Koopmanns under Rule 91a.7. See TEX. R. CIV. P. 91a.7

(providing that the trial court must award attorney’s fees to the “prevailing party” on a 

motion to dismiss). 

2. Burlington and ConocoPhillips Move to Dismiss the Koopmanns’ NonDeclaratory Claims on Summary Judgment

Burlington and ConocoPhillips again moved to dismiss the same claims targeted 

by their Rule 91a motion to dismiss, this time on summary judgment. In support of 

summary judgment, Burlington and ConocoPhillips re-urged some of the same arguments 

that they asserted in their Rule 91a motion to dismiss but also raised a new set of 

arguments as well. This time, the trial court granted summary judgment and dismissed 

all of the Koopmanns non-declaratory claims.4 This appeal followed. 

III. DECLARATORY JUDGMENT 

By their first issue, Strieber, Burlington, and ConocoPhillips contend that the trial 

court erred in declaring on summary judgment that Strieber’s NPRI terminated on 

December 27, 2011. 

 

4 After resolving the Koopmanns lawsuit through final summary judgments, the trial court severed 

Strieber’s cross-claim against Burlington and ConocoPhillips, which placed Strieber’s cross-claim on a 

trajectory for trial pending this appeal. In addition to challenging the trial court’s declaratory judgment in 

favor of the Koopmanns, Strieber individually appeals the trial court’s severance order. 
8

A. Standard of Review

Declaratory judgments decided by summary judgment are reviewed under the 

same standards of review that govern summary judgments generally. See Lidawi v. 

Progressive Cnty. Mut. Ins. Co., 112 S.W.3d 725, 730 (Tex. App.—Houston [14th Dist.] 

2003, no pet.). We review the trial court's summary judgment de novo. See Provident 

Life & Accident Ins. Co. v. Knott, 128 S.W.3d 211, 215 (Tex. 2003). When reviewing a 

summary judgment, we take as true all evidence favorable to the nonmovant, and we 

indulge every reasonable inference and resolve any doubts in the nonmovant's favor. 

Knott, 128 S.W.3d at 215; Sci. Spectrum, Inc. v. Martinez, 941 S.W.2d 910, 911 (Tex. 

1997). When, as here, both parties move for summary judgment on the same issue and 

the trial court grants one motion and denies the other, we consider the summary judgment 

evidence presented by both sides, determine all questions presented, and if we determine

that the trial court erred, render the judgment the trial court should have rendered. See 

FM Props. Operating Co. v. City of Austin, 22 S.W.3d 868, 872 (Tex. 2000). 

B. Discussion 

In order to declare on summary judgment that the Koopmanns own the NPRI, the 

trial court had to find both: (1) that the deed’s savings clause conclusively did not apply 

to preserve Strieber’s interest in the NPRI beyond December 27, 2011; and (2) that the 

rule against perpetuities conclusively did not apply to void the NPRI. We address each 

finding separately below. 

1. Savings Clause 

As per the deed, Strieber’s interest in the NPRI was subject to termination on 

December 27, 2011 unless (1) there was actual production occurring on the Koopmanns’ 
9

land on or before that date, or (2) the savings clause applied to excuse the requirement 

of actual production after that date. Because it is undisputed that no well was actually 

producing by December 27, 2011, the parties agree that Strieber’s interest in the NPRI 

continued beyond that date only if the savings clause applied. Again, the savings clause 

specifically provides that 

[I]f any oil, gas, or mineral or mining lease covering [the Koopmanns’ land] 

is maintained in force and effect by payment of shut-in royalties or any other 

similar payments made to [the Koopmanns] in lieu of actual production while 

there is located on [the Koopmanns’ land] a well or mine capable of 

producing oil, gas, or other minerals in paying or commercial quantities but 

shut-in for lack of market or any other reason, then for purposes of 

determining [whether Strieber’s NPRI continues beyond December 27, 

2011,] it will be considered that production in paying or commercial 

quantities is being obtained from the [Koopmanns’ land]. 

This savings clause contains three key requirements: (1) the lease requirement; 

(2) the capable-well requirement; and (3) the shut-in-royalty-or-similar-payment 

requirement. According to Strieber, Burlington, and ConocoPhillips, all three 

requirements were satisfied on December 27, 2011. First, Burlington had a lease 

covering the Koopmanns’ land—thus satisfying the lease requirement.5 Second, 

Burlington shut-in a well that was capable of producing on or before December 27, 2011—

thus satisfying the capable-well requirement.6 And third, Burlington paid $24,000 to 

extend the lease until October 2012, which is “similar” to a shut-in royalty—thus satisfying 

the shut-in-royalty-or-similar-payment requirement. 

 

5 The parties do not dispute that the lease requirement was satisfied. 

6 The parties’ respective experts, Rhodes and Huddleston, reached different conclusions 

concerning whether the well was capable of producing on or before December 27, 2011. We find that both 

witnesses offered admissible summary judgment testimony. Because the summary judgment evidence 

does not conclusively establish or negate the well’s capability, it is a fact question left for the jury. See Lear 

Siegler, Inc. v. Perez, 819 S.W.2d 470, 471 (Tex. 1991). 
10

Setting aside the first and second requirements, the Koopmanns respond that the 

summary judgment evidence conclusively negates the third requirement and therefore 

renders the savings clause inapplicable to preserve Strieber’s interest in the NPRI beyond 

December 27, 2011. Specifically, the Koopmanns assert that the $24,000 payment 

extending the lease is not “similar” to a shut-in royalty as a matter of law. The question 

therefore becomes one of contract interpretation to ascertain the meaning of the term 

“similar” as it relates to shut-in royalties in the deed’s savings clause. 

(i) Contract Interpretation Principles 

Our primary concern in construing a contract or deed is to ascertain and give effect 

to the true intentions of the parties as expressed in the text of the agreement. El Paso 

Field Services, L.P. v. MasTec North Am., Inc., 389 S.W.3d 802, 805 (Tex. 2012); 

Carbona v. CH Med., Inc., 266 S.W.3d 675, 680 (Tex. App.—Dallas 2008, no pet.). To 

achieve this objective, 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.” Valence Operating Co. v. Dorsett, 164 S.W.3d 656, 662 (Tex. 2005). “No 

single provision taken alone will be given controlling effect; rather, all the provisions must 

be considered with reference to the whole instrument.” J.M. Davidson, Inc. v. Webster, 

128 S.W.3d 223, 229 (Tex. 2003). Contract terms are given “their plain, ordinary, and 

generally accepted meanings unless the contract itself shows them to be used in a 

technical or different sense.” Valence Operating, 164 S.W.3d at 662. 

If a contract can be given a certain or definite legal meaning, then the contract is 

not ambiguous and we will construe it as a matter of law. El Paso Field Servs., 389 

S.W.3d at 806. However, if a contract is susceptible to two or more reasonable 
11

interpretations, then the contract is ambiguous. J.M. Davidson, 128 S.W.3d at 229; 

Seagull Energy E & P, Inc. v. Eland Energy, Inc., 207 S.W.3d 342, 345 (Tex. 2006). When 

a contract is ambiguous, the granting of a motion for summary judgment is usually 

improper because the intent of the contracting parties is an issue of fact for the jury to 

decide. Coker v. Coker, 650 S.W.2d 391, 394 (Tex. 1983); Hackberry Creek Country 

Club, Inc. v. Hackberry Creek Home Owners Ass’n, 205 S.W.3d 46, 56 (Tex. App.—

Dallas 2006, pet. denied).

(ii) Applicable Law 

An oil and gas lease conveys to a lessee a determinable fee to all oil and gas 

below the surface of the land covered by the lease. Cherokee Water Co. v. Forderhause, 

641 S.W.2d 522, 525 (Tex. 1982); ExxonMobil Corp. v. Valence Operating Co., 174 

S.W.3d 303 (Tex. App.—Houston [1st Dist.] 2005, pet. denied). Oil and gas leases are 

divided into two separate time periods, known as the primary and the secondary term. 

Anadarko Petroleum Corp. v. Thompson, 94 S.W.3d 550, 554 (Tex. 2002). 

(a) The Primary Term 

The primary term lasts for a set number of years, which allows the lessee to 

explore, develop, and establish oil and gas production. However, if drilling operations do 

not commence during the primary term, the lessee must pay a fee to the lessor for the 

delay. This fee is called a delay rental. See A. Leopold, 4 TEX. PRACTICE SERIES: LAND 

TITLES & TITLE EXAMINATION § 23.54 n.3 (3d ed. 2005). A delay rental is a periodic 

payment by the lessee for the privilege of deferring exploration and production during the 

primary term of a lease. Id. Delay rentals usually must be paid on the anniversary date 

of the lease's primary term or the lease automatically terminates. Conventional oil and 
12

gas leases require a lessee to pay delay rentals annually during the primary term. 

However, in what is called a “paid-up” lease, the rentals are paid at the time the lease is 

executed. TEX. LAW OF OIL & GAS §4.3[A][3]. 

[A] “paid-up” lease . . . contains no provision for the payment of delay 

rentals. The rentals are paid when the lease is executed, and this single 

payment maintains the lease during the primary term. . . . By paying the 

entire rental up-front, the lessee is relieved of the requirement of annual 

payments . . . 

Id.; see also B. Kramer, Keeping Leases Alive in the Era of Horizontal Drilling and 

Hydraulic Fracturing: Are the Old Workhorses (Shut-in, Continuous Operations, and 

Pooling Provisions) Up to the Task?, 49 WASHBURN L.J. 283, 284 (2010). 

(b) The Secondary Term 

If oil and gas production is established by the end of the primary term, the lease 

will continue into its secondary term and will usually last for as long thereafter as such 

production continues. See Anadarko Petroleum Corp., 94 S.W.3d at 556. However, even 

if production does not occur by the end of the primary term, the lease may contain a 

special provision that operates to maintain the lease in force or carry it into the secondary 

term. This special provision in the lease is known as the savings clause. 

A savings clause is structured to maintain a lease in lieu of actual production in a 

variety of scenarios. One such scenario occurs when the lessee manages to drill a well 

that is capable of producing oil and gas before the end of the primary term, but the well 

cannot be utilized because no market is available to sell the product. See id.; A. Leopold, 

3A TEX. PRACTICE SERIES: LAND TITLES & TITLE EXAMINATION § 14.22.50 (3d ed. 2015) 

(citing In re Estate of Slaughter, 305 S.W.3d 804 (Tex. App.—Texarkana 2010, no pet.)). 

In that situation, the lessee may elect to pay a sum of money to the lessor to keep the 
13

lease maintained during periods of nonproduction until a market opens. Id. This payment 

is called a shut-in royalty. Id. 

“Most law concerning payment of shut-in royalties has developed by analogy to 

delay rentals.” See A. Leopold, 4 TEX. PRACTICE SERIES: LAND TITLES & TITLE EXAMINATION

§ 23.54 n.3. Delay rentals are “periodic payments (usually annual) by the lessee for the 

privilege of deferring exploration during the primary term.” Id. Similarly, shut-in royalties 

are “periodic payments for the privilege of deferring exploration and production after the 

primary term.” Id. “Failure to make either of these payments properly, usually results in 

automatic termination of the lease.” Id. 

(iii) Analysis 

In this case, the savings clause in the 1996 deed specifically provides that shut-in 

royalties are not the exclusive payment-method for maintaining a lease; instead, 

payments “similar” to shut-in royalties are equally acceptable. 

The parties do not dispute that Burlington secured a paid-up lease by paying 

$24,000 to extend the primary term of the lease until October 2012; nor do the parties 

dispute that this payment maintained Burlington’s lease in force and effect on December 

27, 2011—i.e., at the end of Strieber’s initial fifteen-year NPRI term. Instead, the disputed 

issue centers on whether a payment made to secure a paid-up lease is “similar” to a shutin royalty payment. 

According to Strieber, Burlington, and ConocoPhillips, a paid-up lease is similar to 

a shut-in royalty because both are payments from a lessee to a lessor to maintain a lease 

in lieu of actual production. Furthermore, they contend that both payments are permitted 

by a specific clause in an existing lease for the purpose of allowing the lessee to maintain 
14

the lease, at the lessee’s option, for a specific period of time by paying the lessor a 

predetermined sum of money not measured by production. Finally, they contend that 

both payments operate as conditions subsequent because the lease automatically 

terminates if payments are not timely made. In essence, they argue that a paid-up lease 

is too “similar” to be considered different from a shut-in royalty, and therefore, the savings 

clause’s third requirement is satisfied. 

In contrast, the Koopmanns argue that a paid-up lease is too different to be 

considered “similar” to a shut-in royalty. Specifically, the Koopmanns contend that 

although both payments are made during periods of nonproduction and serve to maintain 

a lease, a paid-up lease only secures the lessee’s right to explore and develop during the 

primary term—whereas a shut-in royalty is paid after a well is completed and ready to 

produce but shut-in for lack of market. In other words, a paid-up lease is tied to 

exploration during the primary term whereas a shut-in royalty is tied to production when 

a well capable of producing is shut-in after the primary term. Although the Koopmanns 

maintain that a paid-up lease is different from a shut-in royalty, they provide no example 

of the type of payment that would be similar to a shut-in royalty. 

We note that in analyzing whether a paid-up lease is similar to a shut-in royalty, 

the issue is not whether we believe that the interpretation advanced by one party is more

reasonable or less reasonable than the interpretation advanced by the other party; 

instead, the issue is whether both interpretations satisfy a threshold of reasonableness 

sufficient to conclude that the savings clause is ambiguous on the question of whether a 

paid-up lease is similar to a shut-in royalty. Guided by this perspective, we conclude that 
15

the savings clause is susceptible to at least two different reasonable interpretations. See 

J.M. Davidson, 128 S.W.3d at 229; Seagull Energy E & P, Inc., 207 S.W.3d at 345.

Most notably, a paid-up lease can be similar to (or different from) a shut-in royalty 

depending on the criteria used to compare the two types of payments. For example, if 

the criteria used to compare these payments focuses on when a shut-in royalty is typically 

paid during the life of a lease, then a paid-up lease is different from a shut-in royalty 

because a paid-up lease is paid in the primary term—whereas a shut-in royalty is usually 

paid during the secondary term. If, on the other hand, the criteria used to compare these 

payments focuses on what a shut-in royalty accomplishes during the life of a lease, then 

a paid-up lease is similar to a shut-in royalty—since both payments are made during times 

of nonproduction for the purpose of maintaining a lease in force and effect. The ambiguity 

appears to stem from the fact that the savings clause does not circumscribe the criteria 

for comparing these two types of payments, for example, by defining the term “similar” or 

by listing, describing, or otherwise specifying what types of payments would be similar to 

a shut-in royalty.

7 The Koopmanns further contend that the savings clause does not apply even if a paid-up lease 

is similar to a shut-in royalty. Referencing the placement of the modifier “while” in the savings clause, the 

Koopmanns assert that Burlington’s payment to secure the paid-up lease literally had to be made “while” a 

capable well existed on the Koopmanns’ property. Relying on this interpretation, the Koopmanns point out 

that the undisputed summary judgment evidence showed that Burlington paid for the paid-up lease before 

(not while) a capable well existed on their land, and therefore, the savings clause did not apply. However, 

in order to accept this interpretation, we would have to find that the parties in 1996 intended a future lessee 

in Burlington’s shoes to accomplish the impossible—by requiring the lessee to somehow shut-in a capable 

well on or before the day that it paid for the right to explore and discover oil and gas. See Citizens Nat’l

Bank in Abilene v. Tex. & P. Ry. Co., 150 S.W.2d 1003, 1007 (Tex. 1941) (observing that a contract will not 

be presumed to have imposed an impossible condition on one of the parties); DeNucci v. Matthews, 463 

S.W.3d 200, 217 (Tex. App.—Austin 2015, no pet.); see also Hooks v. Samson Lone Star, Ltd. P'ship, 457 

S.W.3d 52, 63 (Tex. 2015) (observing that courts avoid a contract interpretation that is unreasonable, 

inequitable, and oppressive whenever possible and appropriate). To the extent that a paid-up lease is 

similar to a shut-in royalty, the only reasonable interpretation of the word “while” as used the savings clause 

is that it modifies the lease requirement—meaning that a capable well must exist while the paid-up lease is 

maintained in force and effect, regardless of whether or not a capable well existed at the exact moment in 

time that the lessee paid for the paid-up lease. 
16

As previously mentioned, when a contract is ambiguous, the granting of a motion 

for summary judgment is usually improper because the intent of the contracting parties is 

an issue for the factfinder to determine. Coker, 650 S.W.2d at 394; Hackberry Creek, 

205 S.W.3d at 56. Here, the trial court improperly granted summary judgment over an 

ambiguous deed. Coker, 650 S.W.2d at 394; Hackberry Creek, 205 S.W.3d at 56. 

2. Rule Against Perpetuities 

Notwithstanding the fact issue created by the ambiguous savings clause, Strieber, 

Burlington, and ConocoPhillips request that we reverse the trial court and render a 

judgment that the Koopmanns’ interest in the NPRI violates the rule against perpetuities 

and is therefore void. 

(i) Generally Applicable Law 

The Texas constitution states that “[p]erpetuities . . . are contrary to the genius of 

a free government, and shall never be allowed.” TEX. CONST. art. I, § 26. The rule against 

perpetuities states that no interest is valid unless it must vest, if at all, within twenty-one 

years after the death of some life or lives in being at the time of the conveyance. See 

Peveto v. Starkey, 645 S.W.2d 770, 772 (Tex. 1982). This prohibition is based on the 

policy that society’s best interests are served by promoting the circulation of property in 

commerce. Eugene Kuntz, The Rule Against Perpetuities and Mineral Interests, 8 OKLA.

L. REV. 183, 183 (1955). The rule against perpetuities prevents property interests, 

including mineral interests, from being tied up for such a long period of time that confusion 

results and free alienation of potentially oil-rich land is thwarted. Nelson Roach, The Rule 

Against Perpetuities: The Validity of Oil & Gas Top Leases & Top Deeds in Tex. After 

Peveto v. Starkey, 35 BAYLOR L. REV. 399, 408 (1983). 
17

The word “vest” in the rule refers to an immediate, fixed right of present or future 

enjoyment of the interest. Peveto, 645 S.W.2d at 772. The interest may vest in interest 

before it vests in possession. See Hunt v. Carroll, 157 S.W.2d 429, 436 (Tex. Civ. App.—

Beaumont 1941, writ dism’d). A conveyance challenged under the rule against 

perpetuities must be “viewed as of the date the instrument is executed, and it is void if by 

any possible contingency the grant or devise could violate the [r]ule.” Peveto, 645 S.W.2d 

at 772. 

(ii) Analysis 

Here, the deed reserves the NPRI at issue in Strieber for fifteen years and for as 

long thereafter as production continues, and when production ceases, the NPRI 

automatically goes to the Koopmanns. Strieber, Burlington, and ConocoPhillips contend 

that the NPRI reserved in Strieber for as long as production continues creates a “springing 

executory interest” in the Koopmanns, which is void under the rule against perpetuities. 

a. Bagby 

Our sister court in Bagby rejected this very argument based on a nearly identical 

reservation in a deed. Bagby v. Bredthauer, 627 S.W.2d 190 (Tex. App.—Austin 1981, 

no writ). In Bagby, as here, the grantor reserved a royalty interest for fifteen years, and 

for as long thereafter as production continues. Id. at 193. The court held that this 

reservation created a future interest in the grantee that did not violate the rule against 

perpetuities. Id. at 198. 

In applying the language in the deed to the facts before it, the Bagby court noted 

that the rule against perpetuities “relates only to the vesting of estates and interests and 

has no bearing upon the duration of the estate or the actual possession of it”; that “the 
18

estate or interest may vest in interest before it vests in possession”; and that where an 

instrument is capable of two constructions, preference is given to the construction that 

will uphold the instrument. Id. at 194. 

In applying those basic principles, the Bagby court noted that a Texas landowner 

may create a royalty interest by “grant, reservation, or exception.” Id. at 194–95. The 

court recognized that a “grant” of a royalty interest creates in the grantee a fee simple 

determinable, and establishes in the grantor a possibility of reverter. Id. at 195. A 

“possibility of reverter” is the real property “term of art for what the grantor owns as a 

future interest in a determinable fee grant; it is the grantor's right to fee ownership in the 

real property reverting to him if the condition terminating the determinable fee occurs.” 

Luckel v. White, 819 S.W.2d 459, 464 (Tex. 1991). For example, when the grantor grants 

an NPRI to the grantee for a term of years and for as long thereafter as production 

continues, the grantor retains a possibility of reverter in the NPRI that is conditioned on 

the cessation of production. See Bagby, 627 S.W.2d at 195. The Bagby court correctly 

observed that the grantor’s possibility of reverter following the termination of a 

determinable fee interest in the grantee does not violate the rule against perpetuities. Id. 

The question then became whether a grantor’s “reservation” of an NPRI on a 

determinable fee basis violates the rule against perpetuities when the same interest would 

be valid if created by “grant.” Id. The Bagby court saw no basis for a distinction, 

concluding that “a reservation is the creation, by and in behalf of the grantor, of a new 

right issuing out of the thing granted—something which did not exist as an independent 

right before the grant, a taking back of a part of the thing already granted.” Id. The Bagby

court explained that when, as here, two estates are created in one instrument, it is implied 
19

that the original grantor conveyed the entire surface and mineral estate to the grantee, 

who in turn “re-granted” to the grantor a defeasible term royalty interest that the grantor

intended to reserve. Id. at 195–96. 

This has become known as the “two-grant” theory. The reason for the name is 

that the grantor’s reservation of a royalty interest, such as an NPRI, in a single deed 

actually implies two grants: (1) a grant of a fee simple absolute of the entire estate to the 

grantee; and (2) a re-grant of the royalty interest back to the grantor—thus creating in the 

original grantee a possibility of reverter not voided by the rule against perpetuities. See 

id. Whether effectuated by one grant or two grants, the end result under Bagby is that 

the grantor’s reservation of a defeasible term royalty interest creates a future interest in 

the grantee that does not violate the rule against perpetuities. See id. 

We are persuaded by the reasoning in Bagby and adopt it for purposes of our 

discussion here. Like the deed language in Bagby, the express language of the deed in 

this case demonstrates that Strieber and the Koopmanns intended that the grantor (i.e., 

Strieber) would reserve the NPRI for the period of time indicated in the deed and that, 

upon termination of such interest, the royalty interest would become immediately vested 

in possession in the grantees (i.e., the Koopmanns) without necessity of any further 

conveyance. The fact that the Koopmanns’ interest may not vest in possession until some 

uncertain time in the future does not run afoul of the rule against perpetuities. See Hunt, 

157 S.W.2d at 436. We conclude, as did our sister court in Bagby on nearly identical 

facts, that Strieber’s reservation of the NPRI creates a future interest in the Koopmanns 

that does not violate the rule against perpetuities. See Bagby, 627 S.W.2d at 198; see 

also Walker v. Foss, 930 S.W.2d 701, 705 (Tex. App.—San Antonio 1996, no writ)
20

(observing that the grantor’s royalty reservation for as long as production continues is not 

a perpetuities problem). 

b. Under Bagby’s two-grant theory, does Burlington have a Leasehold on 

the Koopmanns’ Possibility of Reverter in the NPRI?

 Strieber, Burlington, and ConocoPhillips argue that Bagby is a double-edged 

sword that ultimately cuts against the Koopmanns. Specifically, they contend that 

Bagby’s two-grant theory may avoid a perpetuities problem by classifying the 

Koopmanns’ interest in the NPRI as a possibility of reverter; however, they argue that the 

logical sequence of this two-grant theory is that the Koopmanns conveyed the possibility 

of reverter along with the rest of the mineral estate to Burlington when they executed an 

oil and gas lease with Burlington.8 They contend that even assuming that Strieber lost 

the NPRI on December 27, 2011, the NPRI reverted not to the Koopmanns, but instead 

to Burlington because Burlington currently has a leasehold on the Koopmanns’ mineral 

estate, which, according to them, includes the possibility of reverter. They assert that 

under this formulation, Burlington has the exclusive right to receive all royalties 

attributable to the NPRI—perhaps even to the exclusion of Strieber. However, this 

argument is based on the incorrect premise that Burlington has a leasehold on the 

Koopmanns’ possibility of reverter in the NPRI. 

In a typical oil and gas lease, the lessee acquires ownership of all the minerals in 

place that the lessor owned—subject to the lessor’s possibility of reverter in the minerals 

when the lease terminates. See Nat. Gas Pipeline Co. of Am. v. Pool, 124 S.W.3d 188, 

192 (Tex. 2003). The lessor is entitled to, among other things, royalties on production as 

 

8

In other words, Strieber, Burlington, and ConocoPhillips assert that Burlington acquired the 

possibility of reverter in 2010 when Burlington renewed its oil and gas lease for an additional two years, or 

until October 2012. 
21

part of the consideration for the lease. See Concord Oil Co. v. Pennzoil Expl. & Prod. 

Co., 966 S.W.2d 451, 460 (Tex. 1998). When the Koopmanns extended their lease with 

Burlington in 2010, they effectively: (1) conveyed ownership of the minerals to Burlington

for a determinable fee lease term; (2) reserved the right to receive a percentage of 

royalties on production under the lease; and (3) retained a possibility of reverter in the 

minerals upon termination of the lease. See id. The question is whether the Koopmanns’ 

possibility of reverter in the NPRI is (1) a component of the minerals that the Koopmanns 

conveyed to Burlington under the lease, or (2) a component of the royalty interest that the 

Koopmanns retained for themselves.9 We conclude that the possibility of reverter is a 

component of the royalty interest that the Koopmanns retained. 

First, as per the language of the deed, the Koopmanns’ right of reverter in the NPRI 

includes “one-half of the royalties” from production on their land. It is undisputed that 

when Strieber executed the deed in 1996, the land was not leased or producing oil and 

gas. As such, the amount of royalties under the NPRI was to be determined and 

calculated based upon the royalties reserved by the Koopmanns in a future oil and gas 

lease. Given these circumstances, the NPRI is properly classified as a fraction-of-royalty

interest because it was intended to “float” with (or follow) royalties reserved by the 

Koopmanns in a future oil and gas lease. See Coghill v. Griffith, 358 S.W.3d 834, 838 

(Tex. App.—Tyler 2012, pet. denied) (observing that a fraction-of-royalty NPRI conveys 

“a fractional share of the royalty that is contained in an oil and gas lease—it is not fixed, 

but rather floats in accordance with the size of the landowner's royalty contained in the 

 

9 Under this formulation, if the possibility of reverter is a component of the minerals, then Burlington 

arguably has a current leasehold on it.
22

lease”). As a derivative of a floating royalty interest, we believe that the possibility of 

reverter in the NPRI became subsumed under the royalty interest that the Koopmanns 

reserved for themselves under their lease with Burlington.10 Id. 

Second, to classify the possibility of reverter as a mineral interest teeters on the 

absurd in the context of a lessor/lessee relationship. The reality is that the Koopmanns 

leased their minerals to Burlington with the expectation that Burlington would pay them a 

percentage of royalties on oil and gas production from those minerals. In order to accept 

Strieber, Burlington, and ConocoPhillips’ argument, we would have to conclude that the 

Koopmanns somehow intended to convey their reversionary right to receive royalties to 

the very entity from whom they expected to receive royalties—i.e., Burlington. This calls 

into question the consideration supporting the lease in the first place. See Tittizer v. Union 

Gas Corp., 171 S.W.3d 857, 860 (Tex. 2005) (“An oil and gas lease is a contract, and its 

terms are interpreted as such.”); see also Burges v. Mosley, 304 S.W.3d 623, 629 (Tex. 

App.—Tyler 2010, no pet.) (“For a contract to exist, there must be an offer, acceptance, 

 

10 Relying on Monroe v. Scott, Strieber, Burlington, and ConocoPhillips assert that the Koopmanns’ 

possibility of reverter is a component of the mineral estate that the Koopmanns conveyed to Burlington 

under the lease. See 707 S.W.2d 132 (Tex. App.—Corpus Christi 1986, writ ref’d n.r.e.). Under their 

reading of Monroe v. Scott, a possibility of reverter in an NPRI can never be a royalty interest. We do not 

read Monroe v. Scott to support such a broad proposition. In that case, we held that a possibility of reverter 

in an NPRI did not belong with the “royalty interests” retained by the grantor under a partition deed; instead, 

we found that the possibility of reverter was a mineral interest that the grantor conveyed by deed to the 

grantee. Id. at 134. Guided by the precept that the intent of the parties as expressed in the language of 

the deed controls, we found that the grantor’s possibility of reverter in the NPRI was not clearly described 

in the partition deed as a “royalty interest” sufficient to except it from the mineral estate conveyed to the 

grantee. Id. at 133–34. Our holding in Monroe v. Scott was limited to the specific language used in the 

partition deed to determine the intent of the parties with respect to the particular conveyance at issue in that 

case. We did not hold that all reversionary royalty interests are minerals; nor did we hold that such interests 

would be minerals when, as here, there is a lessor/lessee relationship between the grantor and grantee in 

the context of an oil and gas lease. Finally, to the extent that Monroe v. Scott can be read to suggest that 

a possibility of reverter in an NPRI is not a royalty interest, we would conclude that the NPRI at issue in this 

case is distinguishable from the one in Monroe because it is a fraction-of-royalty, which, as explained above, 

floats with the royalty interest that the Koopmanns reserved for themselves under the lease. See id.; see 

also Coghill v. Griffith, 358 S.W.3d 834, 838 (Tex. App.—Tyler 2012, pet. denied). 
23

and consideration.”). For these reasons, we do not believe that Burlington owns a 

leasehold on the Koopmanns’ possibility of reverter under Bagby’s two-grant theory. 

c. Peveto

Finally, Strieber, Burlington, and ConocoPhillips assert that the Texas Supreme 

Court’s 1982 decision in Peveto implicitly overrules Bagby and effectively voids the 

Koopmanns’ interest in the NPRI under the rule against perpetuities. We disagree.

In Peveto, the grantor deeded an NPRI to the grantee for fifteen years and for as 

long thereafter as production continues. Peveto, 645 S.W.2d at 771. Thirteen years into 

the initial fifteen-year period, the grantor conveyed the same NPRI to a different grantee 

using a second deed, which specifically provided that the grant would become “effective 

only upon” the termination of the first deed. Id. The Peveto court voided the second grant 

under the rule against perpetuities because it conveyed a “springing executory interest.”11 

The court observed that the NPRI conveyed under the first deed was a “determinable fee” 

interest because its duration was dependent on oil and gas production, which, according 

to the court, could continue for an indefinite period of time. Id. at 772 (explaining that a 

determinable fee is “an interest which may continue forever, but the estate is liable to be 

determined, without the aid of a conveyance, by some act or event circumscribing its 

continuance or extent”). Turning to the second deed, the court found that the interest 

conveyed therein violated the rule against perpetuities because the words “effective only 

upon [termination of the first deed]” made it so that the second grantee’s interest might 

 

11 An “executory interest” is “a future interest, held by a third person, that either cuts off another's 

interest or begins after the natural termination of a preceding estate.” BLACK'S LAW DICTIONARY (10th ed. 

2014). A “springing executory interest” is a type of executory interest that “operates in defeasance of an 

interest left in the transferor.” Id. 
24

never actually “vest” if the existence of production operated to perpetually preserve the 

NPRI in the first grantee. 

Peveto is distinguishable from this case and Bagby. In Peveto, there were two 

deeds, not one, and the issue was whether the rule against perpetuities voided the second 

deed when the express language of the deed effectively conditioned the grant of a future 

interest itself on the occurrence of an event that might never occur—i.e., cessation of oil 

and gas production. The perpetuities problem in Peveto did not lie in the fact that the 

second grantee’s future interest followed a determinable fee interest, nor did it trouble the 

Peveto court that the first grantee’s interest might continue for an indefinite period of time; 

instead, the perpetuities problem lied in the fact that the grant of the second grantee’s 

future interest was, itself, expressly conditioned upon the termination of the first grantee’s 

interest, which might continue for an indefinite time. For this reason, the second grantee’s 

future interest suffered from a fatal “vesting” problem under the rule against perpetuities. 

This understanding of Peveto is reinforced by the fact that the Supreme Court after Peveto

in Luckel upheld the grant of a similar future interest when, unlike Peveto, the deed did 

not expressly condition the effectiveness of the grant itself on the termination of a 

determinable fee interest. Luckel, 819 S.W.2d at 464 (distinguishing the conveyance in 

Peveto on the basis that the deed did not expressly condition the effectiveness of the 

grant itself on the expiration of the preceding interest). 

Here, as in Luckel and unlike Peveto, the Koopmanns’ future interest in the NPRI 

is created by a single deed, which does not condition the grant of the future interest itself 

on the termination of Strieber’s determinable fee interest; instead, the deed creates a 

presently vested future interest in the Koopmanns. The fact that the Koopmanns future 
25

interest might not result in a possessory right until some uncertain future date does not 

run afoul of the rule against perpetuities. See Hunt, 157 S.W.2d at 436. What matters is 

that the Koopmanns right to the NPRI vested in interest when the deed was executed. 

Id. 

We conclude that Peveto does not overrule Bagby or void the NPRI under the rule 

against perpetuities. We therefore deny Strieber, Burlington, and ConocoPhillips’ request 

that we reverse the trial court’s summary judgment and render a judgment that the rule 

against perpetuities invalidates the NPRI. 

3. Summary 

For the reasons set forth above, we hold that fact issues precluding summary 

judgment exist concerning ownership of the NPRI because the deed’s savings clause is 

ambiguous. As such, the trial court erred in entering a declaration on summary judgment 

that the Koopmanns own the NPRI. We further hold that the rule against perpetuities 

does not apply to invalidate the Koopmanns’ interest in the NPRI. Therefore, we sustain

Strieber, Burlington, and ConocoPhillips’ first issue, reverse the trial court’s declaratory 

judgment, and remand the case to the trial court for further proceedings consistent with 

this opinion.12 

 

12 Based on our disposition of this issue, we need not address the Koopmanns’ second cross-issue, 

in which they seek to recover prejudgment and post-judgment interest on unpaid royalties attributable to 

the NPRI. The reason is that ownership of the NPRI remains an issue to be determined by the factfinder. 

Furthermore, we need not address Strieber’s appeal from the trial court’s order severing her cross-claim 

against Burlington and ConocoPhillips because we are remanding the case to the trial court for further 

proceedings on whether the NPRI terminated. 
26

IV. SUMMARY JUDGMENT DISMISSAL OF THE KOOPMANNS’ NON-DECLARATORY 

CLAIMS AGAINST BURLINGTON AND CONOCOPHILLIPS

By their first cross-issue, the Koopmanns contend that the trial court erred in 

dismissing their non-declaratory claims against Burlington and ConocoPhillips. As the 

summary judgment movant, Burlington and ConocoPhillips had the burden to show that 

no genuine issue of material fact existed as to each of the Koopmanns’ non-declaratory 

claim and that they were therefore entitled to judgment as a matter of law. See TEX. R.

CIV. P. 166a(c). We address the trial court’s dismissal of each claim separately. 

1. Breach of Contract 

The Koopmanns sued Burlington for breach of contract claiming that Burlington 

owes royalties on the NPRI pursuant to the lease agreement. The trial court dismissed 

this claim on summary judgment. Burlington and ConocoPhillips defend the trial court’s 

summary judgment on the basis that section 91.402 of the natural resources code bars 

all of the Koopmanns’ non-declaratory claims, including breach of contract.13 See TEX.

NAT. RES. CODE ANN. § 91.402. Section 91.402 reads as follows: 

(a) [Royalties] must be paid to each [royalty owner] by [the oil-and-gas 

lessee] on or before 120 days after the end of the month of first sale of 

production from the well. . . .

(b) [Royalty payments] may be withheld without interest beyond the time 

limit [] set out in Subsection (a) of this section when there is . . . a dispute 

concerning title that would affect distribution of payments. 

 

13 As a threshold matter, we observe that the unresolved fact issue concerning ownership of the 

NPRI discussed above precludes summary judgment as to this claim. The reason is that Burlington would 

have no obligation to pay royalties on the NPRI under the lease if the savings clause applies to preserve 

the NPRI in Strieber beyond December 27, 2011. However, we must address Burlington and 

ConocoPhillips’ defense of the trial court’s summary judgment under section 91.402 because, if valid, it 

provides an independent basis to affirm the summary dismissal of the Koopmanns’ claim for breach of 

contract. 
27

Id. (emphasis added). Focusing on the italicized language in subsection (b), Burlington 

and ConocoPhillips assert that section 91.402 does not allow royalty owners to bring nondeclaratory claims against lessees who withhold royalties because of a “dispute 

concerning title that would affect distribution of payments.” Reasoning from this 

interpretation of subsection (b), Burlington and ConocoPhillips contend that the trial court 

properly dismissed the Koopmanns’ claim for breach of contract, a non-declaratory claim, 

on summary judgment because ownership of the NPRI is in dispute. We agree that 

ownership of the NPRI is in dispute. However, for two reasons, we disagree that section 

91.402 bars the Koopmanns’ non-declaratory claims because of this dispute. 

First, the House Bill analysis on section 91.402 indicates that the statute was 

designed to protect royalty owners from unjustified payment delays by lessees, while at 

the same time recognizing that such delays sometimes stem from legitimate title disputes. 

See Concord Oil Co. v. Pennzoil Exploration & Prod. Co., 966 S.W.2d 451, 461 (Tex.

1998) (citing bill analysis). Consistent with this purpose, the plain language of section 

91.402 confers a substantive right on royalty owners by imposing a deadline on lessees 

to pay out royalties, while extinguishing interest on late payments when lessees withhold 

royalties because of a title dispute. See TEX. NAT. RES. CODE ANN. § 91.402. With that 

said, no language in subsection (b) can be reasonably understood to bar non-declaratory 

claims as a procedural vehicle for enforcing section 91.402. See id. We will not read into 

the statute a procedural limitation that is not evident from the statute’s plain language. 

See City of Rockwall v. Hughes, 246 S.W.3d 621, 628 (Tex. 2008) (recognizing that courts 

should not read language into a statute when the legislature did not put it there). 

Furthermore, the legislature’s intent not to impose such a procedural limitation on royalty 
28

owners is reinforced by section 91.404(c)—an accompanying section in the natural 

resources code. See TEX. NAT. RES. CODE ANN § 91.404(c) (West, Westlaw through 2015 

R.S.). Section 91.404(c) states that royalty owners have a “cause of action” against 

lessees who violate section 91.402(a). Id. The term “cause of action” is not defined in 

the statute, and there is no indication that the legislature intended the term to exclude 

non-declaratory causes of action.14 Id. 

Second, Burlington and ConocoPhillips’ interpretation of section 91.402(b) is 

inconsistent with the remedial nature of declaratory judgments in general. It is well settled 

that a declaratory judgment coexists with other available remedies—it does not replace 

them. See MBM Fin. Corp. v. Woodlands Operating Co., L.P., 292 S.W.3d 660, 670 (Tex. 

2009) (observing that a declaratory judgment does not supplant all other remedies); Crow 

v. City of Corpus Christi, 146 Tex. 558, 561, 209 S.W.2d 922, 924 (1948). If we were to 

accept Burlington and ConocoPhillips’ interpretation of section 91.402(b), a declaratory 

judgment would essentially become the exclusive remedy for a violation of section 

91.402(a), which is inconsistent with the nature and purpose of a declaratory judgment. 

Absent express legislative direction to the contrary, we will not assume that the legislature 

intended to make declaratory judgments the exclusive remedy for violations of section 

91.402. 

For these reasons, we conclude that a declaratory suit is not the exclusive

procedural vehicle through which royalty owners may recover unpaid royalties from 

 

14 Compare TEX. NAT. RES. CODE ANN. § 91.404(c) (providing that royalty owners have a “cause of 

action” against lessees for section 91.402(a) violations), with id. § 33.171(a) (providing that a “littoral owner 

whose rights may be affected by any action of the [government] under this chapter may bring suit for a 

declaratory judgment against [the government] in a district court in Travis County to try the issues”)

(emphasis added)). 
29

lessees when title to such royalties is in dispute under section 91.402. See TEX. NAT.

RES. CODE ANN. § 91.402. Therefore, the trial court erred in dismissing the Koopmanns’ 

claim for breach of contract, a non-declaratory claim, on the basis that title to the NPRI 

was in dispute. 

2. Unjust Enrichment (and Money Had and Received)

The Koopmanns alleged that ConocoPhillips unjustly enriched itself by retaining 

royalties on the NPRI. The trial court dismissed this claim on summary judgment. 

When, as here, a valid contract covers the subject matter of the parties' dispute, 

there can be no recovery under a quasi-contract theory, such as unjust enrichment. 

Fortune Prod. Co. v. Conoco, Inc., 52 S.W.3d 671, 684 (Tex. 2000) (holding that the 

plaintiff’s claim for unjust enrichment was barred as a matter of law when an express 

contract covered the subject matter of the parties’ dispute). Instead, breach of contract 

is the appropriate theory of recovery. Id. Here, there is no dispute that an express and 

enforceable lease agreement between the parties governs payment of royalties to the 

Koopmanns. 

The Koopmanns maintain that unjust enrichment is a valid theory of recovery 

against ConocoPhillips because only Burlington signed the lease agreement. We 

disagree. The rule barring unjust enrichment not only applies when a plaintiff seeks to 

recover from the party with whom he expressly contracted but also applies when a plaintiff 

seeks to recover from a third party to the contract who benefited from its performance.

Fort Worth 1985, writ ref'd n.r.e.); see also Koenig v. Aetna Life Ins. Co., No. 4:13-CV00359, 2015 WL 6473351, at *7 (S.D. Tex. Oct. 27, 2015). 

Here, there is no dispute that Burlington is a wholly-owned subsidiary of 

ConocoPhillips. Given the unity of financial interest recognized between a parent 

company and its wholly-owned subsidiary, we cannot conclude that ConocoPhillips did 

not benefit from Burlington’s lease to produce and sell oil from the Koopmanns land. See

Copperweld Corp. v. Indep. Tube Corp., 467 U.S. 752, 771 (1984) (observing that “a 

parent and its wholly owned subsidiary have a complete unity of interest”); Cleveland 

Reg'l Med. Ctr., L.P. v. Celtic Props., L.C., 323 S.W.3d 322, 346 (Tex. App.—Beaumont 

2010, pet. denied) (same). Therefore, the trial court correctly dismissed the Koopmanns’ 

unjust enrichment claim against ConocoPhillips as a matter of law because a valid lease 

covers the subject matter of this dispute.

3. Negligence, Negligence per se, and Conversion 

The Koopmanns alleged that Burlington and ConocoPhillips were liable under 

three tort theories for failing to pay royalties—negligence, negligence per se, and 

conversion. The trial court dismissed these tort claims based on Burlington and 

ConocoPhillips’ summary judgment argument that the claims are barred by the economic 

loss rule. On appeal, the Koopmanns argue that the claims fall outside the scope of the 

economic loss rule, which makes the trial court’s dismissal improper. 

(i) Applicable Law 

The economic loss rule provides that where the damage sought by the plaintiff in 

a tort action is only the economic loss to the subject of a contract itself, the remedy 

ordinarily is one of contract alone, not tort. See Formosa Plastics Corp. USA v. Presidio 

Eng'rs & Contractors, Inc., 960 S.W.2d 41, 47 (Tex. 1998). In other words, when damage 

allegedly resulting from the defendant’s tortious conduct is limited to the loss of a 

contractual benefit, the economic loss rule applies to bar the action in tort. See Chapman 

Custom Homes, Inc. v. Dallas Plumbing Co., 445 S.W.3d 716, 718 (Tex. 2014) (per 

curiam); Sw. Bell Tel. Co. v. DeLanney, 809 S.W.2d 493, 494 (Tex. 1991). However, the 

economic loss rule does not preclude recovery in tort when the defendant, in performing 

a contract, breaches a legal duty owed to the plaintiff that is independent of the contractual 

undertaking and that results in damage to the plaintiff above and beyond the mere 

economic loss of the contractual benefit itself. See DeLanney, 809 S.W.2d at 494. To 

determine whether a particular claim sounds in tort or contract, our focus is on the 

substance of the claim and not simply on the manner in which it has been pled. See Clark 
32

v. PFPP Ltd. P'ship, 455 S.W.3d 283, 288 (Tex. App.—Dallas 2015, no pet.) (citing Jim 

Walter Homes, Inc. v. Reed, 711 S.W.2d 617, 617–18 (Tex. 1986)). 

To illustrate the economic loss rule, the cases of DeLanney and Scharrenbeck are 

instructive. See DeLanney, 809 S.W.2d at 494; Montgomery Ward & Co. v. 

Scharrenbeck, 204 S.W.2d 508, 510 (Tex. 1947). In DeLanney, the Texas Supreme 

Court held that the economic loss rule barred the plaintiff’s negligence suit against a 

telephone company for failing to publish the plaintiff’s advertisement in the yellow pages 

as required by their contract. DeLanney, 809 S.W.2d at 495. The court found that the 

telephone company’s duty to publish the plaintiff’s advertisement arose solely from the 

contract and that the plaintiff’s damages were only for the economic loss caused by the 

telephone company’s failure to perform under the contract. Id. Thus, the court held that 

the telephone company’s alleged negligence in failing to publish the advertisement could 

not be brought as a tort because the plaintiff’s injury was only the economic loss to the 

subject matter of the contract itself. Id. 

The DeLanney court distinguished Scharrenbeck—a case in which the court had 

previously allowed a plaintiff to maintain a negligence suit despite the economic loss rule. 

Scharrenbeck, 204 S.W.2d at 510. In Scharrenbeck, the plaintiff sued the defendant for 

negligence, alleging that the defendant’s negligent repair of the plaintiff’s water heater 

burned down the plaintiff’s entire home. Id. The plaintiff sought recovery for the damage 

to his home, which had been completely destroyed by the negligently repaired water 

heater. Id. In finding that the economic loss rule did not bar the plaintiff’s negligence 

claim, the court observed that although the contract obligated the defendant to put the 

plaintiff’s water heater back in good working order, tort law also implied a general duty on 
33

the defendant to act with reasonable care in making the repairs so as not to injure a 

person or property by his performance. Id. Distinguishing Scharrenbeck, the DeLanney

court observed: 

Accompanying every contract is a common-law duty to perform with care, 

skill, reasonable expedience and faithfulness the thing agreed to be done, 

and a negligent failure to observe any of these conditions is a tort, as well 

as a breach of the contract. . . . In failing to repair the water heater properly, 

the defendant [in Scharrenbeck] breached its contract. In burning down 

plaintiff's home, the defendant [in Scharrenbeck] breached a common-law 

duty as well, thereby providing a basis for plaintiff's recovery in tort. . . . If 

the defendant's conduct—such as negligently burning down a house—

would give rise to liability independent of the fact that a contract exists 

between the parties, the plaintiff's claim may also sound in tort. Conversely, 

if the defendant's conduct—such as failing to publish an advertisement—

would give rise to liability only because it breaches the parties' agreement, 

the plaintiff's claim ordinarily sounds only in contract.

DeLanney, 809 S.W.2d at 494.

(ii) Analysis 

In view of the forgoing, we must determine whether the economic loss rule applies 

to bar the Koopmanns’ tort claims when their lease with Burlington governs payment of 

royalties. Here, the Koopmanns alleged that Burlington and ConocoPhillips were 

negligent in failing to pay royalties: (1) by not properly managing and administering the 

lease as a reasonably prudent operator; (2) by not executing the lease with the requisite 

level of care, skill, reasonable expedience, and faithfulness; and (3) by not cooperating in 

the performance of the lease.

15

 The Koopmanns further alleged that Burlington and 

ConocoPhillips were negligent per se by failing to timely pay royalties in violation of 

 

15 To support these omissions, the Koopmanns further alleged that Burlington and ConocoPhillips: 

(a) attempted to conceal that Strieber’s NPRI term had expired on December 27, 2011; (b) attempted to 

maintain Burlington’s 60% interest in Strieber’s NPRI by tendering a shut-in royalty payment in December 

2011 when no such payment was required; (c) failed to properly inspect pertinent documents governing the 

payment of royalties owed to the Koopmanns; and (d) failed to make the proper royalty payments to the 

Koopmanns when such payments were due. 
34

section 91.402 of the natural resources code. Finally, the Koopmanns alleged that 

Burlington and ConocoPhillips committed the tort of conversion by exercising dominion 

and control over royalties owned by them.16 

Although artfully pleaded in the language of torts, the substance of the 

Koopmanns’ claims sound in contract. Each tort claim essentially concerns 

Burlington’s—and its parent company’s—failure to pay royalties under a valid and 

enforceable lease agreement. No economic loss other than unpaid royalties is alleged. 

Unlike the defendant in Scharrenbeck, Burlington’s and ConocoPhillips’ conduct would 

give rise to liability only because failing to pay royalties breaches the parties’ lease 

agreement, not because there exists some general duty in tort law to pay royalties 

independent of a contractual duty to do so. Furthermore, unlike the plaintiff in 

Scharrenbeck—who lost not only the contractual benefit of a working water heater but 

also his entire home—the Koopmanns’ loss is limited to the contractual benefit of the 

lease itself—i.e., royalties.17 See Exxon Mobil Corp. v. Kinder Morgan Operating L.P. 

"A'', 192 S.W.3d 120, 127–29 (Tex. App.—Houston [14th Dist.] 2006, no pet.) (barring tort 

claim where the rights of the parties in regard to propane gas were governed by the 

contract between them, and the only loss that the plaintiff complained about was loss of 

propane); Castle Texas Prod. Ltd. P'ship v. Long Trusts, 134 S.W.3d 267, 275 (Tex. 

 

16 See Bandy v. First State Bank, Overton, 835 S.W.2d 609, 622 (Tex. 1992) (defining conversion 

as the wrongful exercise of dominion and control over another's property that is inconsistent with the 

property owner’s rights). 

17 In their reply brief, the Koopmanns argue that their conversion claim not only seeks recovery of 

unpaid royalties due under the lease but also seeks recovery for the “wrongful” acts of Burlington and 

ConocoPhillips. The Koopmanns do not specify what acts were wrongful and, more importantly, do not 

explain how those acts caused losses separate and apart from the economic loss of royalties due under 

their lease. Looking at the substance of their conversion claim, the Koopmanns cannot avoid application 

of the economic loss rule when the alleged wrongdoing, if any and at best, amounts only to a breach of 

contract. See Sw. Bell Tel. Co. v. DeLanney, 809 S.W.2d 493, 494 (Tex. 1991). 
35

App.—Tyler 2003, pet. denied) (rejecting conversion claim where the only loss alleged 

was the economic loss to the subject matter of the contract); Harrison v. Bass Enterprises 

Prod. Co., 888 S.W.2d 532, 536 (Tex. App.—Corpus Christi 1994, no writ) (rejecting 

negligence and negligence per se claims because the plaintiff’s only damage was unpaid 

royalties under a contract); see also Dhanani v. Giles, No. 10-07-00144-CV, 2008 WL 

2210004, at *4 (Tex. App.—Waco May 28, 2008, pet. denied) (mem. op.) (rejecting 

conversion claim where the defendant’s dominion and control over the plaintiff's property 

was tantamount to a breach of the governing contract). Therefore, we conclude that the 

trial court properly dismissed the Koopmanns’ claims against Burlington and 

ConocoPhillips for negligence, negligence per se, and conversion under the economic 

loss rule. 

4. Summary 

For the reasons set forth above, we sustain the Koopmanns’ first cross-issue to 

the extent that it contends that the trial court erred in dismissing the Koopmanns’ claim 

for breach of contract. However, we overrule the Koopmanns’ first cross-issue to the 

extent that it contends that the trial court erred in dismissing the Koopmanns’ claims for 

unjust enrichment, money had and received, negligence, negligence per se, and 

conversion. 

V. ATTORNEY’S FEES

As previously mentioned, Burlington and ConocoPhillips moved for an early 

dismissal of all of the Koopmanns’ claims under Texas Rule of Civil Procedure 91a. The 

trial court denied the motion to dismiss and awarded attorney’s fees to the Koopmanns 

on the motion but then later granted summary judgment dismissing the Koopmanns’ 
36

claims. By a second issue, Burlington and ConocoPhillips request that we vacate the trial

court’s order awarding attorney’s fees to the Koopmanns because the claims lack a basis 

in law and fact under Rule 91a and, as such, should have been dismissed by the trial 

court before the summary judgment stage. 

A. Standard of Review and Applicable Law 

We review de novo a trial court’s ruling on a motion to dismiss under Rule 91a. 

See Wooley v. Schaffer, 447 S.W.3d 71, 73–77 (Tex. App.—Houston [14th Dist.] 2014, 

no pet.); DeVoll v. Demonbreun, No. 04-14-00116-CV,___S.W.3d___,2014 WL 7440314, 

at *2 (Tex. App.—San Antonio Dec. 31, 2014, no pet.). Rule 91a.1 provides that “a party 

may move to dismiss a cause of action on the grounds that it has no basis in law or fact.” 

TEX. R. CIV. P. 91a.1. A cause of action has no basis in law “if the allegations, taken as 

true, together with inferences reasonably drawn from them, do not entitle the claimant to 

the relief sought.” Id. A cause of action has no basis in fact “if no reasonable person 

could believe the facts pleaded.” Id. The trial court “may not consider evidence in ruling 

on the motion and must decide the motion based solely on the pleading of the cause of 

action, together with any pleading exhibits [.]” Id. R. 91a.6. We construe the pleadings 

liberally in favor of the nonmovant. See City of Dallas v. Sanchez, 449 S.W.3d 645, 650 

(Tex. App.—Dallas 2014, no pet.). 

Rule 91a.7 contains a loser-pays provision concerning attorney’s fees. See TEX.

R. CIV. P. 91a.7. It provides that the trial court must award to the “prevailing party” all 

reasonable and necessary attorney’s fees incurred with respect to the cause of action

challenged under Rule 91a. Id. 
37

B. Analysis 

The record reflects that Burlington and ConocoPhillips sought early dismissal of 

the Koopmanns’ claims under Rule 91a based on the following two main grounds: (1) 

section 91.402(b) of the natural resources code bars all of the claims; and (2) the 

economic loss rule bars only the negligence claims. 

With respect to the first ground, we determined in Part IV(1) of this opinion that 

section 91.402(b) of the natural resources code does not bar a claim for breach of 

contract—or any other non-declaratory claim for that matter—brought by a royalty owner 

to recover unpaid royalties. Thus, to the extent that Burlington and ConocoPhillips’ Rule 

91a motion sought to dismiss all of the Koopmanns’ claims under section 91.402(b), the 

trial court properly denied the motion. 

However, with respect to the second ground, we determined in Part IV(3)(ii) of this 

opinion that the economic loss rule bars the Koopmanns’ negligence claims as a matter 

of law; therefore, the trial court properly granted summary judgment dismissing those 

claims. Given the trial court’s summary judgment, the question is whether Burlington and 

ConocoPhillips should be considered the “prevailing party” entitled to recover attorney’s 

fees under Rule 91a.7. We believe that Burlington and ConocoPhillips have failed to 

meet their appellate burden to demonstrate that they are entitled to prevailing-party status 

in this situation. First, they provide no argument or authority that, after liberally construing 

the Koopmanns’ pleadings, the economic loss rule renders the negligence claims legally 

or factually baseless under Rule 91a.1. See Wooley, 447 S.W.3d at 73–77 (providing 

that courts are to liberally construe the pleadings in favor of the nonmovant on a Rule 91a 

motion). Second, even assuming that the negligence claims are baseless and should 
38

have been dismissed on the pleadings, Burlington and ConocoPhillips provide no 

argument or authority that a dismissal of those claims would entitle them to prevailingparty status under Rule 91a.7 when, under that formulation, the Koopmanns are still the 

“prevailing party” with respect to the majority of the claims, including: (1) breach of 

contract; (2) unjust enrichment/money had and received; and (3) conversion. See

Timothy Patton, Motions to Dismiss Under Texas Rule 91a: Practice, Procedure and 

Review, 33 REV. LITIG. 469, 567–68 (2014) (recognizing that Texas courts have struggled 

to identify who, precisely, “prevailed” in a particular lawsuit under a “loser-pays” provision,

such as Rule 91a.7, when the lawsuit involves multiple claims and the movant arguably

prevails in dismissing some but not all of the claims on the pleadings); see also TEX. R.

CIV. P. 91a.7. 

For the reasons set forth above, we conclude that the trial court properly denied

Burlington and ConocoPhillips’ motion to dismiss. Because the Koopmanns successfully 

defeated the motion to dismiss, the trial court correctly found that they were entitled to 

recover attorney’s fees under Rule 91a.7. See TEX. R. CIV. P. 91a.7. We therefore 

overrule Burlington and ConocoPhillips’ second issue. 

VI. CONCLUSION

Accordingly, we affirm the trial court’s final judgment, in part, as follows: (1) the 

trial court’s dismissal of the Koopmanns’ claims for unjust enrichment, money had and 

received, negligence, negligence per se, and conversion; and (2) the trial court’s award 

of attorney’s fees to the Koopmanns pursuant to Texas Rule of Civil Procedure 91a.7. 

Further, we reverse, in part, the trial court’s final judgment as follows: (1) the trial court’s 

dismissal of the Koopmanns’ claim for breach of contract; and (2) the trial court’s 
39

declaratory judgment. We remand for further proceedings consistent with Parts III and IV 

of this opinion.
