The RRC has issued one drilling permit (amended once), issued October 5, 2006, permitted to 8,057 ft.
It was permitted by Highmount Expl & Prod Texas LLC and has since transferred to Upp Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.
Its 2 leases have reported 40 barrels of oil and 204K mcf of gas since November 2006, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
