Midland County · Spraberry (Trend Area) field · Producing · Vertical
Jacwil B #2 (API 42-329-31101) is a well in Midland County operated by Discovery Operating Inc., completed February 8, 1993 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1982 and 1992, permitted to 11,450 ft.
It was permitted by Texaco E & P Inc. and has since transferred to Discovery Operating Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Up Spraberry, Lo Spraberry.
Its 2 leases have reported 109K barrels of oil and 154K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
