The RRC has issued one drilling permit, issued August 18, 2014, permitted to 12,500 ft.
It was permitted by Oxy USA Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Queen, Grayburg, San Andres.
Its 2 leases have reported 4.52M barrels of oil and 10.2M mcf of gas since April 2008, last reporting in July 2026. The leases carry 127 wells, so these are lease totals, not this well alone.
