Refugio County · Mary Ellen Oconnor (Stray A) field · Vertical
Oconnor Mary Ellen #38 (API 42-391-30568) is a plugged well in Refugio County, plugged November 12, 2021, last operated by Dolphin Petroleum LP.
The RRC has issued 3 drilling permits between 1987 and 1995, permitted to 6,400 ft.
It was permitted by Citation Oil & Gas Corp. and has since transferred to Dolphin Petroleum LP on the wellbore schedule.
Its 3 leases have reported 250K barrels of oil and 697K mcf of gas since January 1993, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Citation Oil & Gas Corp.; the EWA schedule now lists a different operator.
