Borden County · Blackard (Spraberry) field · Vertical
Msw Brown B #1 (API 42-033-31165) is a well in Borden County operated by Estancia Oil & Gas LLC, completed March 12, 1998.
The RRC has issued 2 drilling permits between 1985 and 1998, permitted to 9,900 ft.
It was permitted by Ricks Exploration, Inc. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.
Completion filings report 14 formation tops, including Spraberry, Upr. Sprby, Lwr. Sprby, Blackard.
Its 3 leases have reported 231K barrels of oil and 141K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 11.4K barrels injected in the 12 months reported through August 2025.
