Heard Clement #27U
Refugio County · Tom Oconnor (5900 Sand) field · Vertical
Heard Clement #27U (API 42-391-31689) is a well in Refugio County operated by Hilcorp Energy Company, completed January 10, 1984.
The RRC has issued 2 drilling permits between 1983 and 1988, permitted to 6,100 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 7 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.
Its 2 leases have reported 24.1M barrels of oil and 15.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 614 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 3.21M barrels injected in the 12 months reported through September 2025.
