constitutional as applied to lands conveyed to the United States prior to the effective date of its enactment.
In Louisiana there is no land tenure other than perfect ownership and imperfect ownership and there is no separate corporeal mineral estate in oil and gas as such. The Louisiana courts have adhered to the principle that a reservation or sale of oil and gas creates only a right to go upon the land to search for and capture minerals. This right to reduce the substance to possession, although not fitting perfectly into any civil code category, is in the nature of a servitude on land in favor of a person, to be governed by the laws of Louisiana pertaining to servitudes. Frost-Johnson Lumber Co. v. Sailing’s Heirs, 150 La. 756, 91 So. 207. The mineral servitude can only be created by the landowner through such acts as are used in the transfer of title to immovable property. Long-Bell Petroleum Co. v. Tritico, 216 La. 426, 43 So.2d 782, 791; Revised Civil Code, Articles 743, 766, 770. It is extinguished by the prescription resulting from nonuser of the servitude for ten years following the execution of the deed conveying the right. Frost-Johnson Lumber Co. v. Nabors Oil and Gas Co., 149 La. 100, 88 So. 723. Revised Civil Code, Articles 789, 3546. However, user of a mineral servitude will preserve it for another ten years. Lee v. Giauque, 154 La. 491, 97 So. 669; Louisiana Petroleum Co. v. Broussard, 172 La. 613, 135 So. 1. These principles are well established.
It is equally clear that the reservation or grant of mineral rights in several noncontiguous tracts of land creates separate servitudes and the drilling on one noncontiguous tract of land does not interrupt the running of prescription against the rights in another tract of land. Lee v. Giauque, 154 La. 491, 97 So. 669, 670. However, where several landowners agree to unitize or integrate their mineral interests in various tracts of land, in order to better secure development thereof, and provide for the payment of the proceeds in the proportion which their mineral interests bear to the whole, their agreement is governed by the law of contracts and not by the law of servitudes. In such instances the land is treated as a whole and it is immaterial whether the lands are contiguous or noncontiguous. Brown v. Sugar Creek Syndicate, 195 La. 865, 197 So. 583; Robinson v. Horton, 197 La. 919, 2 So.2d 647; Veeder Company Inc. v. Pan American Production Company, 205 La. 599, 17 So.2d 891; Dobbins v. Hodges, 208 La. 143, 23 So.2d 26; Farrell v. Simms, 209 La. 1072, 26 So.2d 143; Jackson v. Hunt Oil Co., 208 La. 156, 23 So.2d 31.
One of the principal issues in this case relates to the pooling agreement. It is conceded that this agreement was never recorded and despite this fact appellee contends that appellant was charged with notice thereof by virtue of the language employed in the deed from Bodcaw to Good Pine Oil. We think otherwise. Article 2266 of the Revised Civil Code provides that “All sales, contracts and judgments affecting immovable property, which shall not be so recorded, shall be utterly null and void, except between the parties thereto.” This Article is applicable to mineral servitudes and “must be complied with religiously.” Haynes v. King, La.Sup., 52 So.2d 531, 539. It is therefore clear that this pooling agreement cannot affect the rights of appellant, a third party.
This brings us to a consideration of the Constitutional questions. In the year 1940 the Louisiana Legislature enacted Act No. 315, which reads in part as follows: “When land is acquired by conventional deed or contract, condemnation or expropriation proceedings by the United States of America, or any of its subdivisions or agencies, from any person, firm, or corporation, and by the act of acquisition, verdict, or judgment, oil, gas, or other minerals or royalties are reserved, or the land so acquired is by the act of acquisition conveyed subject to a prior sale or reservation of oil, gas, or other minerals or royalties, still in force and effect, the rights so reserved or previously sold shall be imprescribable.” LSA-Revised Statutes of Louisiana, Title 9, Section 5806. In Whitney National Bank of New Orleans v. Little Creek Oil Company, Inc., La., 33 So.2d 693, the Supreme Court of Louisiana had
