Maude Williams ET AL 'B' #17 (API 42-391-00519) is a former disposal or injection well in Refugio County, last operated by Hilcorp Energy Company; its UIC permit is no longer active.

The RRC has issued 4 drilling permits between 2001 and 2017, permitted to 5,923 ft.

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

Its 4 leases have reported 23.8M barrels of oil and 15.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 639 wells, so these are lease totals, not this well alone.
