Cole Ranch -35- #207H (API 42-173-36816) is a horizontal well in Glasscock County operated by Diamondback E&P LLC, completed August 24, 2015 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued October 23, 2014, permitted to 9,500 ft.

It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 2.13M barrels of oil and 10.5M mcf of gas since July 2010, last reporting in July 2026. The lease carries 40 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
