Downie Ranch -6- #5
Pecos County · Thistle (Overthrust) field · Vertical
Downie Ranch -6- #5 (API 42-371-35912) is a well in Pecos County operated by Sandridge Expl. And Prod. LLC, completed May 1, 2008.
The RRC has issued one drilling permit (amended once), issued March 11, 1987, permitted to 3,500 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Sandridge Expl. And Prod. LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Base Cretaceous (marker), Caballos, Ordovician.
Its 3 leases have reported 29.9K barrels of oil and 528K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
