Usm Hillin -B- #1 (API 42-371-33700) is a well in Pecos County operated by Stablerock Energy L.L.C., completed February 2, 1982.

The RRC has issued one drilling permit, issued January 8, 1982, permitted to 4,100 ft.

It was permitted by Gulf Oil Corp. and has since transferred to Stablerock Energy L.L.C. on the wellbore schedule.

Its 2 leases have reported 52.5K barrels of oil and 32.1K mcf of gas since January 1993, last reporting in July 2026. The leases carry 75 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
