Sherman County · Coldwater Ranch (Marmaton) field · Producing · Vertical
Coldwater Ranch Unit #9 (API 42-421-30355) is a well in Sherman County operated by Burk Royalty CO. Ltd., completed October 22, 1986 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 4, 1985, permitted to 5,650 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Burk Royalty CO. Ltd. on the wellbore schedule.
Completion filings report 5 formation tops, including Brown Dolomite, Douglas, Tonkawa, Kansas City.
Its lease has reported 1.35M barrels of oil and 1.14M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 33 wells, so these are lease totals, not this well alone.
