Hillin-Winfield #3 (API 42-371-34622) is a well in Pecos County operated by Stablerock Energy L.L.C., completed July 27, 1984.
The RRC has issued one drilling permit, issued February 27, 1984, permitted to 3,700 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Stablerock Energy L.L.C. on the wellbore schedule.
Completion filings report one formation top, including Pay.
Its 2 leases have reported 70.7K barrels of oil and 61.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 77 wells, so these are lease totals, not this well alone.
