Downie Ranch #407 (API 42-371-35637) is a well in Pecos County operated by Sandridge Energy Inc., completed April 26, 1988.
The RRC has issued one drilling permit, issued October 21, 1985, permitted to 3,500 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Sandridge Energy Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Base Cretaceous (marker), Caballos, Ordovician.
Its 2 leases have reported 285K barrels of oil and 493K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
