Heard Wilson A #1 (API 42-391-00745) is a well in Refugio County operated by Quintana Pet. Corp., completed August 27, 1977.

The RRC has issued 4 drilling permits (amended twice) between 1977 and 2011, permitted to 5,945 ft.

It was permitted by Hilcorp Energy Company and has since transferred to Quintana Pet. Corp. on the wellbore schedule.

Completion filings report 6 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 6 leases have reported 279K barrels of oil and 1.11M mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 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.
