Coldwater Ranch Unit #6 (API 42-421-30349) is a well in Sherman County operated by Burk Royalty CO. Ltd., completed December 23, 1985.
The RRC has issued one drilling permit, issued January 23, 1985, permitted to 5,750 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 8 formation tops, including Brown Dolomite, U. Penn, Pennsylvanian, Douglas.
Its lease has reported 1.35M barrels of oil and 1.14M mcf of gas since January 1993, last reporting in July 2026. The lease carries 33 wells, so these are lease totals, not this well alone.
