Refugio County · Mary Ellen Oconnor (D-1) field · Vertical
O Conner Mary Ellen #23 (API 42-391-01872) is a plugged well in Refugio County, plugged May 5, 2022, last operated by Dolphin Petroleum LP.
The RRC has issued one drilling permit, issued April 12, 1978, permitted to 6,000 ft.
It was permitted by Amoco Production Company and has since transferred to Dolphin Petroleum LP on the wellbore schedule.
Its lease has reported 86.9K barrels of oil and 486K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Amoco Production Company; the EWA schedule now lists a different operator.
