Crockett County · Farmer (San Andres) field · Producing · Vertical
University (M) B #4 (API 42-105-35753) is a well in Crockett County operated by Digital Operating Company LLC, completed March 14, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 14, 1990, permitted to 2,650 ft.
It was permitted by Pro Oil and has since transferred to Digital Operating Company LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 90K barrels of oil and 200K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Pro Oil; the EWA schedule now lists a different operator.
