The RRC has issued one drilling permit (amended 3 times), issued April 20, 2010, permitted to 10,018 ft.

It was permitted by Hilcorp Energy Company and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Anacacho, Austin Chalk, Ef, Buda.

Its 2 leases have reported 15.1M barrels of oil and 18.5M mcf of gas since May 2010, last reporting volume in April 2026. The leases carry 62 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
