The RRC has issued one drilling permit (amended once), issued August 28, 2017, permitted to 11,000 ft.
It was permitted by Cog Operating LLC and has since transferred to U.S. Energy Development Corp on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, Yates, Queen, Seven Rivers.
Its lease has reported 819K barrels of oil and 1.99M mcf of gas since June 2012, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
