Sibley 48 #8 (API 42-371-37572) is a well in Pecos County operated by P.O.&G. Operating LLC, completed October 7, 2007 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued June 6, 2005, permitted to 7,000 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to P.O.&G. Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Bell Canyon, Cherry Canyon, Manzanita D Top, Rhoda Walker A.
Its lease has reported 744K barrels of oil and 3.97M mcf of gas since April 2003, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
