George A. SARANDOS and Athena Sarandos, Appellants,
v.
Laura Lee BLANTON, Appellee.
No. 10-98-364-CV.
Court of Appeals of Texas, Waco.
July 26, 2000.
*812 Russell Horn, Dan Miller, McElroy, Sullivan, Ryan & Miller, L.L.P., Austin, for appellant.
Michael P. Graham, Stephen G. Tipps, Gretchen Allen, Baker & Botts, Houston, for appellee.
Before Chief Justice DAVIS, Justices VANCE and GRAY.
REX D. DAVIS, Chief Justice.
Laura Lee Blanton filed suit against George A. Sarandos and his wife Athena to quiet title to minerals located in and under a 60.652-acre tract of land. Laura claims title by virtue of a 1987 mineral deed from her father. George and Athena claim ownership of minerals by adverse possession under a vacancy awarded George and his brother Ernest in 1977 by the Commissioner of General Land Office (the "Commissioner"). The facts are not disputed, and the parties filed competing summary judgment motions. After hearing, the court granted Laura's motion and decreed that she owns the minerals in question.
George and Athena claim under a single point of error that the court erred in granting Laura's motion for summary judgment and denying their own because: (1) their possession of the surface under a vacancy award granting surface and mineral estates constitutes adverse possession of the minerals as a matter of law; and (2) drilling and production of previously severed minerals was unnecessary to establish adverse possession when the competing claimant to the minerals had notice of their adverse claim and acquiesced to that claim for more than ten years.

BACKGROUND
Laura's father E. C. Scurlock conveyed what was believed to be a 739.1-acre tract of land (the "Scurlock tract") located on the border of Leon and Freestone Counties to Lon Morris College in 1963, reserving all mineral interests to himself. Lon Morris College sold the property to Tommy Lynn Turner in 1964. Turner sold the property in 1967 to George and Ernest Sarandos. Since that time, the Sarandoses have made improvements, hunted, grazed cattle, and paid taxes on the property.
In 1975, George and Ernest made application with the General Land Office (the "GLO") as good faith claimants to purchase a suspected vacancy located within this property.[1]See Act of May 9, 1939, 46th Leg., R.S., ch. 3, § 1(f), 1939 Tex. Gen. Laws 465, 470-71, repealed by Act of May 24, 1977, 65th Leg., R.S., ch. 871, § 16, 1977 Tex. Gen. Laws 2345, 2697. The County Surveyor of Leon County surveyed *813 the land and determined that a 178.02-acre vacancy existed within the Scurlock tract. The surveyor also concluded that the Scurlock tract actually contained 802.15 acres, rather than the 739.1 acres previously believed. Based on this survey (the "Sarandos survey"), the Commissioner determined that the vacancy existed, and the School Land Board fixed its price at $62,307. Id.
The State awarded the vacancy to George and Ernest in January 1977, reserving a one-sixteenth royalty interest in oil and gas and a one-eight royalty in all other minerals. In July, George and Ernest partitioned their acreage (i.e., both the 178.02-acre vacancy and the 802.15 acres disclosed by the Sarandos survey). In this partition, Ernest's conveyance to George purported to include 76.48 acres out of the 178.02-acre vacancy, and George's conveyance to Ernest purported to include the southernmost 101.54 acres from the vacancy. The 60.652 acres presently in dispute all lie within George's 76.48 acres.[2]
In 1978, Scurlock executed a mineral lease in favor of Kimball Production Company conveying an interest in the minerals in the Scurlock tract, described as containing 739.1 acres, consistent with the legal description in his 1963 deed to Lon Morris College. In 1980, George and his wife Athena executed a mineral lease in favor of Seneca Resources Corporation on their portion of the 178.02-acre vacancy tract. Ernest and his wife Sharon executed a similar lease on the same date. Kimball notified Scurlock in 1981 that it wanted to reduce its delay rentals because of the Sarandoses' apparent ownership of the 178.02 acres acquired from the State. Kimball supported this request with a 1980 title opinion describing the history of the property and the Sarandoses' claim. Kimball tendered an agreement reducing the delay rentals to Scurlock for his signature. However, the record does not reflect whether Scurlock ever signed this agreement.
In 1987, Scurlock conveyed the mineral estate of the 739.1-acre tract to his daughter Laura Blanton, expressly referencing the property descriptions contained in his 1963 deed to Lon Morris College and the 1952 deeds by which he received the two tracts comprising this acreage. Laura's husband Jack sent a copy of the 1980 title opinion received from Kimball to an independent landman for review acknowledging, "It may be that we have 624.13 acres in this tract or it may be 802.1." Eight days later, Laura executed a mineral lease in favor of Wisenbaker Production Company on 544.13 out of 802.15[3] acres, expressly excepting the 178.02-acre tract claimed by George and Ernest. George and Athena executed a mineral lease in favor of Wisenbaker on their portion of the 178.02-acre tract two months later. Ernest and his wife Sharon executed a similar lease on the same date.
In 1994, George and Athena executed a mineral lease in favor of Jordan Oil & Gas Company on their portion of the 178.02-acre tract. Ernest and Sharon executed a similar lease on the same date covering the remainder of that tract. That same year, Laura executed a mineral lease in favor of Sonat Exploration Company on the 544.13 acres she had previously leased to Wisenbaker. In April 1995, Sonat notified Laura that she should be credited with an additional 80 acres out of the 802.15-acre *814 tract. Accordingly, Laura executed a "Correction of Lease Description" amending her 1994 lease to cover 624.13 acres rather than 544.13.
Ernest Sarandos conveyed a surface estate of 307.843 acres to Houston Lighting & Power Company (HL & P) in 1995, including his 101.54 acres out of the 178.02-acre tract. Tyler surveyor Bill H. Burton prepared a survey report for HL & P to review the accuracy of the Sarandos survey. Burton concluded that the Sarandoses' tract actually contains only 177.582 acres (not 178.02); that 60.652 of these acres lay within the original Scurlock tract and thus within the mineral estate owned by Laura; and that there were "pure vacancies" totaling only 116.929 acres. One month later, the GLO notified George that the acreage in the vacancy award was being reduced to 116.93 acres in accordance with Burton's report and that the purchase price was being reduced to reflect this decrease in acreage to the point that he owed only $90.80 to pay it off.
The GLO received a $90.80 payment in January 1996.[4] Laura executed another corrective lease description in favor of Sonat in April, increasing the acreage by adding the 60.652 acres disclosed by Burton. In June, Sonat drilled an exploratory gas well which proved successful. The GLO issued a patent in the name of George and Ernest Sarandos in August for 116.93 acres. Five days later, Laura filed suit against the Sarandoses and others for a declaratory judgment to quiet title to the minerals in and under the disputed 60.652 acres.
In December, the GLO received a payment of $6,440.66 from the Sarandoses, which is the amount that would still be owed had the GLO not reduced the acreage in the vacancy award. Twelve days later, the GLO notified George that the $90.80 had been received in January "making the file paid in full," the patent had issued, and the $6,440.66 overpayment was being refunded.

STANDARD OF REVIEW
When the parties have filed competing motions for summary judgment and one is granted while the other is denied, an appellate court may consider the propriety of the denial as well as the granting. Commissioners Court v. Agan, 940 S.W.2d 77, 81 (Tex.1997); McCreight v. City of Cleburne, 940 S.W.2d 285, 287-88 (Tex.App.-Waco 1997, writ denied). If the pertinent facts are undisputed, the court can determine the issues presented as a matter of law. McCreight, 940 S.W.2d at 288. In this situation, the court will either affirm the judgment or reverse and render. Jones v. Strauss, 745 S.W.2d 898, 900 (Tex.1988); Tobin v. Garcia, 159 Tex. 58, 64, 316 S.W.2d 396, 400-01 (1958).[5] However, if resolution of the issues rests in disputed facts, summary judgment is inappropriate, and the court will reverse and remand. See Coker v. Coker, 650 S.W.2d 391, 394-95 (Tex.1983); McCreight, 940 S.W.2d at 288.

ADVERSE POSSESSION OF SEVERED MINERALS
George and Athena argue in their sole point that they have established title to the minerals under the disputed acreage by adverse possession because: (1) their possession of the acreage under a vacancy award which purported to convey both surface and mineral estates constitutes adverse possession of both estates as a matter of law; and (2) Laura had actual notice of their claim for more than ten years and acquiesced to it. Laura responds that because George and Athena have never drilled or produced any minerals from the *815 disputed acreage, they cannot establish title to the previously-severed mineral estate by adverse possession.

APPLICABLE LAW
The statutory definition of the term "adverse possession" has remained essentially unchanged for more than a century. Compare TEX. CIV. PRAC. & REM.CODE ANN. § 16.021(1) (Vernon 1986) with Mhoon v. Cain, 77 Tex. 316, 318, 14 S.W. 24, 24 (1890) (quoting article 3198 of 1879 Revised Civil Statutes). The current statute provides:
"Adverse possession" means an actual and visible appropriation of real property, commenced and continued under a claim of right that is inconsistent with and is hostile to the claim of another person.
TEX. CIV. PRAC. & REM.CODE ANN. § 16.021(1).[6]
To prevail on an adverse possession claim, the claimant must establish all the required elements. See Rhodes v. Cahill, 802 S.W.2d 643, 645 (Tex.1990); Amador v. Berrospe, 961 S.W.2d 205, 208 (Tex.App.-Houston [1st Dist.] 1996, pet. denied). Thus, a party claiming title by adverse possession must, at a minimum, prove the following:
 actual possession of the disputed property;
 under a claim of right;
 which is adverse or hostile to the claim of another.[7]
See Haby v. Howard, 757 S.W.2d 34, 37 (Tex.App.-San Antonio 1988, writ denied); Ramirez v. Wood, 577 S.W.2d 278, 287 (Tex.Civ.App.-Corpus Christi 1978, no writ); see also TEX. CIV. PRAC. & REM.CODE ANN. § 16.021(1).
Concerning the first element, settled case law in Texas establishes that, after the mineral and surface estates have been severed, an adverse possessor of the surface estate cannot accomplish adverse possession of the mineral estate unless he takes actual possession of minerals under the surface by drilling and producing them for the statutorily-prescribed period. Thedford v. Union Oil Co., 3 S.W.3d 609, 615 (Tex.App.-Dallas 1999, pet. denied); Garza v. Maddux, 988 S.W.2d 280, 289-90 (Tex.App.-Corpus Christi 1999, pet. denied) (op. on reh'g); Sun Operating Ltd. Partnership v. Oatman, 911 S.W.2d 749, 757 (Tex.App.-San Antonio 1995, writ denied); see also Elliott v. Nelson, 113 Tex. 62, 251 S.W. 501, 504 (1923); Thomas K. McElroy, Adverse Possession of Mineral Estates, 11 BAYLOR L.REV. 253, 258 (1959).
In Orsborn v. Deep Rock Oil Corp., the Supreme Court addressed the second statutory element, the "claim of right." 153 Tex. 281, 290-91, 267 S.W.2d 781, 787 (1954). The Court stated:
No matter how exclusive and hostile to the true owner the possession may be in appearance, it cannot be adverse unless accompanied by the intent on the part of the occupant to make it so. The naked possession unaccompanied with any claim of right will never constitute a bar.
Id. at 291, 267 S.W.2d at 787 (quoting Houston Oil Co. v. Stepney, 187 S.W. 1078, 1084 (Tex.Civ.App.-Beaumont 1916, writ ref'd)); accord Boyle v. Burk, 749 S.W.2d *816 264, 266 (Tex.App.-Fort Worth 1988, writ denied).

ANALYSIS
George and Athena argue that the drilling and production requirement should not apply in their case because they adversely possessed the disputed acreage under a vacancy award from the sovereign which purported to convey both surface and mineral estates. We disagree.
The Supreme Court addressed a remarkably similar fact situation in Atlantic Refining Co. v. Noel. 443 S.W.2d 35 (Tex.1969) (op. on reh'g). In that case, a survey was made of two tracts of land in Upton County in 1881. The Commissioner patented the odd numbered sections in these two blocks to the Missouri, Kansas and Texas Railroad Company. In 1904, John R. Johnston applied for a patent to section 26 of block 1. The next year H.R. Smith applied for a patent to section 10 of block 1. The Commissioner awarded these sections to Johnston and Smith on the basis of the 1881 survey.
Union Land Company came into possession of sections 10 and 26 through mesne conveyances from the original awardees. At that time, these sections remained unpatented because the full purchase price had not yet been paid to the State. In 1913, the Commissioner ordered a resurvey of block 1 at Union Land's request. The surveyor failed to utilize at least twelve of the monuments set by the prior surveyor in 1881. The resurvey revealed that each of the sections contained 670 acres rather than the 640 acres found by the original surveyor. In addition, because the surveyor ignored several of the monuments set in 1881 and located new ones to correspond to his resurvey, apparent vacancies were "discovered" along the northern borders of sections 10 and 26.
Union Land conveyed sections 10 and 26 to Cordova Union Oil Corporation in 1926. Cordova Union conveyed the minerals in and under sections 10 and 26 to Atlantic Refining Company in 1943, thereby severing the surface and mineral estates in these tracts. Cordova Union later conveyed the surface estates in the tracts to two other parties. The mortagee for these surface owners paid off the debt owed to the State for sections 10 and 26 in 1946 whereupon the Commissioner issued patents in the names of the original awardees (Johnston and Smith). The legal descriptions in these patents were based on the 1913 resurvey rather than the original 1881 survey.
W.D. Noel filed an application with the Commissioner in 1961 to lease the minerals in the two vacancies apparently disclosed by the 1913 resurvey. The Commissioner determined that the alleged vacancies existed, granted Noel's application, and later issued patents to the surface owners as good faith claimants.
It was subsequently determined that the 1913 survey was incorrect and the alleged vacancies did not exist. Atlantic Refining filed a trespass to try title suit against Noel and the surface owners. Noel and the owners responded that Atlantic Refining was estopped to deny the existence of the vacancies. The Supreme Court rejected this argument stating:
The act relied upon for the creation of an estoppel against Atlantic Refining Company as owner of the mineral estate is the act of the owners of the surface to Sections 26 and 10. It is an act of the surface owners done long after the mineral and surface estate had been severed and after Atlantic obtained its title to the minerals in 1943. To estop Atlantic under such circumstances would mean that the owner of a mineral estate can be estopped by conduct of the surface owner over whom he has no right of control. It would mean that a mineral owner may be estopped by the conduct of the surface owner after the severance of the mineral and surface estates and about which the mineral owner had neither constructive nor actual notice.
*817 Atlantic Refining Co., 443 S.W.2d at 39-40. The Court also observed:
A rule which would permit the acts of a surface owner to reduce the ownership of the mineral estate, even without notice or knowledge of the facts by the mineral owner, is one which should be announced with some caution. It would mean that Cordova Union, which owned both the minerals and surface prior to 1943 could first convey the minerals, later accept a patent with reduced acreage, and estop its vendee even though this would be in derogation of its own deed. Cordova Union could then assert a good faith claim not only to the surface but to the mineral estate which it had effectively defeated. Cordova Union could, sub silentio, empower its remote surface vendees with the same power to accept a patent and reduce the mineral acreage.
Id. at 41.
We believe these concerns apply with equal force to George and Athena's argument that the requirement of drilling and production for adverse possession of severed minerals should not apply to them. To allow George and Athena to establish a limitations title to a previously-severed mineral estate without actually taking possession of the minerals would raise concerns identical to those expressed by the Supreme Court in Atlantic Refining. See id. at 39-41. Accordingly, we conclude that George and Athena may not rely on the erroneous vacancy award to establish a limitations title to previously-severed minerals which they never drilled or produced. See Thedford, 3 S.W.3d at 615; Garza, 988 S.W.2d at 289-90; Sun Operating, 911 S.W.2d at 757; McElroy, supra, at 258.
George and Athena also argue that they established a limitations title under the ten-year statute because Laura and her father were aware of their claim to the minerals and acquiesced to their claim for more than ten years. See TEX. CIV. PRAC. & REM.CODE ANN. § 16.026 (Vernon Supp.2000). Under this theory, they assert that actual possession of the disputed minerals is unnecessary when the owner has actual notice of the adverse claim. They rely on Orsborn v. Deep Rock Oil Corp. to support this argument.
As previously noted, the Supreme Court in Orsborn addressed the second element required to establish adverse possession, the "claim of right." See Orsborn, 153 Tex. at 290-91, 267 S.W.2d at 787; Boyle, 749 S.W.2d at 266. By conveying an interest in the minerals in a 1980 mineral lease, the Sarandoses established that they exercised a "claim of right" to the disputed minerals sufficient to satisfy the second element of their adverse possession claim. Their summary judgment proof also establishes that Blanton acquiesced in their claim when she executed the mineral lease in favor of Wisenbaker in August 1987, expressly excepting the 178.02-acre tract from the lease. Her acquiescence continued until April 1996 when she amended her mineral lease with Sonat to include the 60.652 acres ultimately determined to lie outside of the vacancy and within the original Scurlock tract.[8]
Even if George and Athena established the requisite "claim of right" however, Blanton's summary judgment proof establishes that they never acquired actual possession of the disputed minerals by drilling and production. See Thedford, 3 S.W.3d at 615; Garza, 988 S.W.2d at 289-90; Sun Operating, 911 S.W.2d at 757; McElroy, supra, at 258. They argue that drilling and production should be unnecessary in a case such as theirs. However, our research has disclosed no cases supporting *818 this contention. Therefore, because the undisputed evidence establishes that George and Athena never took actual possession of the disputed minerals, Blanton is entitled to judgment as a matter of law. See McCreight, 940 S.W.2d at 288.

CONCLUSION
It is undisputed that George and Athena never drilled or produced any minerals from the acreage in question. Thus, they never took actual possession of the previously-severed mineral estate. For this reason, they failed to establish their entitlement to judgment as a matter of law on their claim of title by adverse possession. See American Tobacco Co. v. Grinnell, 951 S.W.2d 420, 425 (Tex.1997). Accordingly, we overrule their sole point of error and affirm the judgment. See Jones, 745 S.W.2d at 900; Tobin, 159 Tex. at 64, 316 S.W.2d at 400-01.
NOTES
[1]  The statute then in effect defined a "good faith claimant" as "any person ... occupying or using, or theretofore occupying or using, or whose predecessors in interest, have occupied or used a vacancy for purposes other than exploring for or removing oil, gas, sulphur, or other minerals therefrom with a good faith belief that the same was included within the boundaries of a survey or surveys previously titled, awarded or sold under circumstances that would, at the time the vacancy issue arose, have vested title thereto had said area actually been located within said survey or surveys, and whose said boundaries are shown to have been recognized boundaries in the community. Provided a person... or those under whom he claims, shall have said land in his inclosure or under definite recognized boundaries and be in possession thereof for a period of ten (10) years with a good faith belief that he was the owner thereof and that same was included within his survey." Act of May 9, 1939, 46th Leg., R.S., ch. 3, § 1(a), 1939 Tex. Gen. Laws 465, 465-66, repealed by Act of May 24, 1977, 65th Leg., R.S., ch. 871, § 16, 1977 Tex. Gen. Laws 2345, 2697.
[2]  In 1997, Ernest Sarandos and his wife Sharon executed a mineral deed in favor of George Sarandos and his wife Athena which grants the minerals in and under the land conveyed to George in the 1977 partition. Although they executed the mineral deed twenty years after the partition, the deed purports to be "effective as of [the date of the partition]."
[3]  Thus, even though Scurlock purported to convey a 739.1-acre mineral estate to Laura, she apparently accepted the conclusions of the 1975 resurvey and the 1980 title opinion that the tract actually contained 802.15 acres.
[4]  The record does not affirmatively reflect the source of this payment. George denies that he made it.
[5]  When the parties' motions are premised differently, the court may also reverse and remand. See Sosa v. Williams, 936 S.W.2d 708, 711 & n. 1 (Tex.App.-Waco 1996, writ denied).
[6]  Article 3198 of the 1879 Revised Civil Statutes defined "adverse possession" as "an actual and visible appropriation of the land, commenced and continued under a claim of right inconsistent with and hostile to the claim of another." See Mhoon v. Cain, 77 Tex. 316, 318, 14 S.W. 24, 24 (1890).
[7]  Such a party must also prove other elements which vary depending on whether he seeks to establish title by adverse possession under the three-year, five-year, ten-year, or twenty-five-year limitations statute. See TEX.CIV.PRAC. & REM. CODE ANN. §§ 16.028 (Vernon 1986 & Supp. 2000); see also Haby v. Howard, 757 S.W.2d 34, 37 (Tex. App.-San Antonio 1988, writ denied); Ramirez v. Wood, 577 S.W.2d 278, 287 (Tex. Civ. App.-Corpus Christi 1978, no writ) (both construing requirements of 10-year limitations statute).
[8]  The Sarandoses claim that Blanton and her father acquiesced in their claim for more than ten years. However, they failed to conclusively establish this. They presented no summary judgment evidence demonstrating that Scurlock acceded to Kimball Production Company's 1981 request to reduce its rentals because of the Sarandoses' claim. Thus, they did not conclusively establish any acquiescence until August 1987, when Blanton executed a mineral lease expressly excepting from its coverage the 178.02 acres claimed by the Sarandoses.
