Wilson Heard-6600 Sand Unit-B- #8 (API 42-391-30199) is a well in Refugio County operated by Amoco Production Company, completed April 29, 1972.
The RRC has issued 3 drilling permits between 1991 and 2012, permitted to 6,750 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Amoco Production Company on the wellbore schedule.
Completion filings report 2 formation tops, including Frio, No Change.
Its 4 leases have reported 20.8K barrels of oil and 1.71M mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
