Oconnor Mary Ellen #1 (API 42-391-01977) is a plugged well in Refugio County, plugged April 16, 2009, last operated by Dolphin Petroleum LP.

The RRC has issued one drilling permit, issued March 11, 1987, 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 2 leases have reported 86.9K barrels of oil and 575K mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 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.
