Borden County · Blackard (Spraberry) field · Vertical
Msw Brown #2 (API 42-033-31100) is a well in Borden County operated by Estancia Oil & Gas LLC, completed October 10, 2008.
The RRC has issued 3 drilling permits between 1984 and 1987, permitted to 10,050 ft.
It was permitted by Exxon Corp. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Spraberry, Wolfcamp, Pennsylvanian, Strawn.
Its 2 leases have reported 565K barrels of oil and 357K 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.
