Heard, Fannie V.W. Mrs. #21

Heard, Fannie V.W. Mrs. #21 (API 42-391-00690) is a former disposal or injection well in Refugio County, last operated by Hilcorp Energy Company; its UIC permit is no longer active.

The RRC has issued 9 drilling permits (amended twice) between 1984 and 2023, permitted to 5,925 ft.

Completion filings report 7 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 5 leases have reported 26.5M barrels of oil and 17.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 731 wells, so these are lease totals, not this well alone.
