Williams Maude et al A #D 12
Refugio County · Lake Pasture (FT-570) field · Vertical
Williams Maude ET AL A #D 12 (API 42-391-00277) is a well in Refugio County operated by Quintana Pet. Corp., completed June 15, 1989.
The RRC has issued 7 drilling permits between 1988 and 2017, permitted to 5,760 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Quintana Pet. Corp. on the wellbore schedule.
Completion filings report 10 formation tops, including Lagarto, L-167, L-200, Oakville.
Its 6 leases have reported 466K barrels of oil and 1.58M mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
