Heard Ira -B- 6600 Sand Unit #A016 (API 42-391-30235) is a well in Refugio County operated by Quintana Pet. Corp., completed April 27, 1973.

The RRC has issued 4 drilling permits (amended once) between 1998 and 2015, permitted to 6,754 ft.

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

Completion filings report 7 formation tops, including Surface Sand Clay, Lagarto, Oakville, Catahoula.

Its 4 leases have reported 22.8M barrels of oil and 15.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 597 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.
