Williams Maude Etal -A- #D133 (API 42-391-31781) is a well in Refugio County operated by Hilcorp Energy Company, completed August 14, 1987 and listed as injection on the RRC schedule.

The RRC has issued 2 drilling permits between 1984 and 1987, permitted to 4,701 ft.

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

Completion filings report 9 formation tops, including Recent (Water Sand), Lagarto, Oakville, Catahoula.

Its lease has reported 11.1M barrels of oil and 179M mcf of gas since January 1993, last reporting in July 2026. The lease carries 176 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 386K barrels injected in the 12 months reported through October 2025.
