Sibley Effie ET AL State #5 (API 42-371-35184) is a well in Pecos County operated by Stablerock Energy L.L.C., completed December 11, 1984.
The RRC has issued one drilling permit, issued November 5, 1984, permitted to 3,800 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 Redbed.
Its 2 leases have reported 162K barrels of oil and 214K mcf of gas since January 1993, last reporting in July 2026. The leases carry 81 wells, so these are lease totals, not this well alone.
