Last week the San Antonio Court of Appeals decided Lightning Oil Company v. Anadarko, No. 04-14-001152-CV, a case involving “mineral trespass.” What is interesting about the case is what the court did not decide.
Lightning Oil Company owns two oil and gas leases covering 3,250 acres within the Briscoe Ranch in Dimmit County. The Briscoe Ranch owns the surface but not the minerals in this 3,250 acres. To the south of Lightning’s leases is the Chaparral Wildlife Management Area, a wildlife sanctuary managed by Texas Parks and Wildlife Department. TPWD owns the surface and 1/6 mineral interest in the Chaparral WMA. The Light family (some of whom own Lightning Oil) own the other 5/6 mineral interest. Anadarko holds oil and gas leases on the Chaparral WMA.
The TPWD lease to Anadarko prevents use of the surface of the Chaparral WMA for oil and gas wells except with TPWD consent, and says that Anadarko must use off-site drilling locations “when prudent and feasible.” Anadarko made an agreement with Briscoe Ranch to use the surface of the Ranch to drill horizontal wells under the Chaparral WMA. The first location Anadarko chose is located on the land covered by the Lightning Oil Company leases. So Anadarko proposed to drill a horizontal well from a surface location on Lightning’s lease; the well would penetrate the Eagle Ford formation on Lightning’s lease, but no perforations, or “take points,” in the well would be located on Lightning’s lease.
