Sibley Effie Potts -B- #5 (API 42-371-33126) is a well in Pecos County operated by P.O.&G. Operating LLC, completed July 17, 1980 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 13, 1980, permitted to 5,100 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.
Its lease has reported 174K barrels of oil and 382K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
