WELL · 42-371-32455 · DISTRICT 8
Sibley Unit #4
Pecos County · Four C (San Andres) field · Vertical
Sibley Unit #4 (API 42-371-32455) is a well in Pecos County operated by Warren Joe H., completed March 10, 1978.
The RRC has issued one drilling permit, issued January 6, 1978, permitted to 2,500 ft.
It was permitted by Four C Oil & Gas Corp. and has since transferred to Warren Joe H. on the wellbore schedule.
Its 2 leases have reported 1.25M barrels of oil and 35.7K mcf of gas since January 1993, last reporting in July 2026. The leases carry 40 wells, so these are lease totals, not this well alone.
