Glasscock County · Spraberry (Trend Area) field · Shut IN · Horizontal
Calverley 9-4 #11H (API 42-173-37493) is a horizontal well in Glasscock County operated by Cog Operating LLC, completed November 29, 2017 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 7, 2016, 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 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 3.71M barrels of oil and 21.7M mcf of gas since October 2015, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
