Ratliff R. H. #12 (API 42-227-33716) is a well in Howard County operated by Marathon Oil Company, completed July 5, 1985.

The RRC has issued one drilling permit, issued April 16, 1985, permitted to 2,500 ft.

It was permitted by Guthrie, A. K. Operating CO. and has since transferred to Marathon Oil Company on the wellbore schedule.

Completion filings report one formation top, including San Andrs.

Its 3 leases have reported 2.09M barrels of oil and 97.3K mcf of gas since January 1993, last reporting in July 2026. The leases carry 284 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
