Oil and Gas Well Records

The Railroad Commission of Texas maintains historical information that is used by employees, other state agencies, local government, the oil and gas industry, and the general public in its Central Records and Imaging units. An estimated 132 million pages of analog and digital documents encompassing the history of each Texas oil and natural gas well from the drilling permit application to the final plugging report are preserved.

Search Oil and Gas Well Records - Oil and Gas Well Records can be searched by key fields or full text. The Oil and Gas Potential profile includes applications to drill, oil and gas completion reports, plugging reports, producer's transportation authority and miscellaneous records from 1964 to present.  The Well Log (WL) profile includes images of all well logs received since July 2004.

General Information Pertaining to Leases and Royalites

This outline is provided as an informal guide to members of the public seeking information or legal services the Railroad Commission of Texas cannot provide. Since the Texas Legislature has given the Railroad Commission of Texas limited authority to regulate the oil and gas industry in Texas, our staff cannot advise you in all oil and gas matters. Areas over which the Railroad Commission of Texas has no authority include lease and royalty matters (including leasing, payment of royalties and the right to receive royalties), the financing of or investment in oil and gas activities, property rights matters and bankruptcy.
