Jacobs Livestock B #2 (API 42-461-32066) is a plugged well in Upton County, plugged January 18, 2016, last operated by Extex Operating Company.
The RRC has issued 4 drilling permits between 1983 and 2000, permitted to 9,400 ft.
It was permitted by Samson Lone Star LP and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report 11 formation tops, including San Andres, Intra Wolfcamp Detrital, Intra Wolfcamp Dexrital, Permian (undifferentiated).
Its 2 leases have reported 51.8K barrels of oil and 375K 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.
