The RRC has issued one drilling permit, issued July 14, 2011, permitted to 7,800 ft.
It was permitted by Granite Operating Company and has since transferred to Presidio Petroleum LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Anhydrite, Brown Dolomite, Blue Shale, Base Heebner / Top Douglas.
Its lease has reported 183K barrels of oil and 1.47M mcf of gas since December 2011, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
