Keystone Cattle CO. #345 (API 42-495-31069) is a plugged well in Winkler County, plugged December 13, 2005, last operated by Xto Energy Inc..
The RRC has issued one drilling permit, issued June 21, 1979, permitted to 3,880 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Colby, Colby Dolomite, Colby Lower Pay, Grayburg.
Its lease has reported 24.4K barrels of oil and 776K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 55 wells, so these are lease totals, not this well alone.
