Pecos County · Coyanosa N. (Delaware) field · Injection · Vertical
Sibley Effie Potts #12 (API 42-371-33594) is a well in Pecos County operated by P.O.&G. Operating LLC, completed April 9, 2003 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued October 13, 1981, permitted to 5,500 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to P.O.&G. Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Lamar, Delaware.
Its lease has reported 139K barrels of oil and 655K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 29.3K barrels injected in the 12 months reported through May 2025.
