"We do not regard as authoritative the three decisions by the Supreme Court of Louisiana to the effect that an adjoining owner is without right of action for gas wasted from the common pool by his neighbor, because in that state only qualified ownership of oil and gas is recognized, no absolute ownership of minerals in place exists, and the unqualified rule is that under the law of capture the minerals belong exclusively to the one that produces them. Louisiana Gas & Fuel Co. v. White Bros., 157 La. 728, 103 So. 23; McCoy v. Arkansas Naturals Gas Co., 175 La. 487, 143 So. 383, 85 A.L.R. 1147, certiorari denied 287 U.S. 661, 53 S.Ct. 220, 77 L.Ed. 570; McCoy v. Arkansas Natural Gas Co., 184 La. 101, 165 So. 632. Moreover, from an examination of those cases it will be seen that the decisions rested in part on the theory that “the loss complained of was, manifestly, more a matter of uncertainty and speculation than of fact or estimate.” In the more recent trend of the decisions of our state, with the growth and development of scientific knowledge of oil and gas, it is now recognized “that when all oil field has been fairly tested and developed, experts can determine approximately the amount of oil and gas in place in a common pool, and can also equitably determine the amount of oil and gas recoverable by the owner of each tract of land under certain operating conditions.” Brown v. Humble Oil & Refining Co., 126 Tex. 296, 83 S.W.2d 935, 940, 87 S.W.2d 1069, 99 A.L.R. 1107, 101 A.L.R. 1393. In Texas, and in other jurisdictions, a different rule exists as to ownership. In our state the landowner is regarded as having absolute title in severalty to the oil and gas in place beneath his land. Lemar v. Garner, 121 Tex. 502, 50 S.W.2d 769; Humphreys-Mexia Co. v. Gammon, 113 Tex. 247, 254 S.W. 296, 29 A.L.R. 607; Waggoner Estate v. Sigler Oil Co., 118 Tex. 509, 19 S.W.2d 27; Texas Co. v. Daugherty, 107 Tex. 226, 176 S.W. 717, L.R.A. 1917F, 989. The only qualification of that rule of ownership is that it must be considered in connection with the law of capture and is subject to police regulations. Brown v. Humble Oil & Refining Co., supra. The oil and gas beneath the soil are considered a part of the realty. Each owner of land owns separately, distinctly and exclusively all the oil and gas under his land and is accorded the usual remedies against trespassers who appropriate the minerals or destroy their market value. Peterson v. Grayce Oil Co., Tex.Civ.App., 37 S.W.2d 367, affirmed 128 Tex. 550, 98 S.W.2d 781; Comanche Duke Oil Co. v. Texas Pac. Coal & Oil Co., Tex.Com.App., 298 S.W. 554; Calor Oil & Gas Co. v. Franzell, 128 Ky. 715, 109 S.W. 328; Louisville Gas Co. v. Kentucky Heating Co., 117 Ky. 71, 77 S.W. 368, 70 L.R.A. 558, 111 Am.St.Rep. 225; Id., 132 Ky. 435, 111 S.W. 374; Ross v. Damm, 278 Mich. 388, 270 N.W. 722; 31A Tex.Jur. 911, Sec. 530; Id. 924, Sec. 537; 24 Am.Jur. 641, Sec. 159. The conflict in the decisions of the various states with reference to the character of ownership is traceable to some extent to the divergent views entertained by the courts, particularly in the earlier cases, as to the nature and migratory character of oil and gas in the soil. 31A Tex.Jur. 24, Sec. 5. In the absence of common law precedent, and owing to the lack of scientific information as to the movement of these minerals, some of the courts have sought by analogy to compare oil and gas to other types of property such as wild animals, birds, subterranean waters and other migratory things, with reference to which the common law had established rules denying any character of ownership prior to capture. However, as was said by Professor A. W. Walker, Jr., of the School of Law of the University of Texas: “There is no oil or gas producing state today which follows the wild-animal analogy to its logical conclusion that the landowner has no property interest in the oil and gas in place.” 16 T.L.R. 370, 371. In the light of modern scientific knowledge these early analogies have been disproven, and courts generally have come to recognize that oil and gas, as commonly found in underground reservoirs, are securely entrapped in a static condition in the original pool, and, ordinarily, so remain until disturbed by penetrations from the surface. It is further established, nevertheless, that these minerals will migrate across property lines towards any low pressure area created by production from the common pool. This migratory character of oil and gas has given rise to the so-called rule or law of capture. That rule simply is that the owner of a tract of land acquires title to the oil or gas which he produces from wells on his land, though part of the oil or gas may have migrated from adjoining lands. He may thus appropriate the oil and gas that have flowed from adjacent lands without the consent of the owner of those lands, and without incurring liability to him for drainage. The non-liability is based upon the theory that after the drainage the title or property interest of the former owner is gone. This rule, at first blush, would seem to conflict with the view of absolute ownership of the minerals in place, but it was otherwise decided in the early case of Stephens County v. Mid-Kansas Oil & Gas Co., 1923, 113 Tex. 160, 254 S.W. 290, 29 A.L.R. 566. Mr. Justice Greenwood there stated, 113 Tex. 167, 254 S.W. 292, 29 A.L.R. 566: The objection lacks substantial foundation that gas or oil in a certain tract of land cannot be owned in place, because subject to appropriation, without the consent of the owner of the tract, through drainage from wells on adjacent lands. If the owners of adjacent lands have the right to appropriate, without liability, the gas and oil underlying their neighbor’s land, then their neighbor has the correlative right to appropriate, through like methods of drainage, the gas and oil underlying the tracts adjacent to his own. Thus it is seen that, notwithstanding the fact that oil and gas beneath the surface are subject both to capture and administrative regulation, the fundamental rule of absolute ownership of the minerals in place is not affected in our state."
