Refugio County · Tom Oconnor field · Shut In · Vertical
Williams Maude Etal -A- #15 (API 42-391-00474) is a well in Refugio County operated by Hilcorp Energy Company, completed June 30, 1995 and listed as shut in on the RRC schedule, shut in January 1, 2007.
The RRC has issued 5 drilling permits between 1979 and 1994, permitted to 6,200 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.
Its 4 leases have reported 23.3M barrels of oil and 15.9M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 629 wells, so these are lease totals, not this well alone.
