Overton B. #36 (API 42-227-34221) is a well in Howard County operated by Citation Oil & Gas Corp., completed January 13, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued October 21, 1987, permitted to 2,550 ft.
It was permitted by Conoco Inc. and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 4 formation tops, including U. Grayburg, Grayburg, L. Grayburg, San Andres.
Its 2 leases have reported 2.46M barrels of oil and 54.6K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 75 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 215K barrels injected in the 12 months reported through December 2025.
