Calverley 27 #3 (API 42-173-36928) is a plugged well in Glasscock County, plugged May 22, 2024, last operated by Cog Operating LLC.

The RRC has issued one drilling permit, issued October 8, 2014, permitted to 12,000 ft.

It was permitted by Rsp Permian, LLC and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 175K barrels of oil and 722K mcf of gas since January 1993, last reporting in May 2024. The lease carries 9 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.
