The RRC has issued one drilling permit (amended once), issued April 25, 2006, permitted to 12,208 ft.

It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.

Completion filings report 11 formation tops, including T/Brown Dolomite, B/Heebner-T/Douglas, T/Tonkawa, Avant Ls.

Its 2 leases have reported 12.8K barrels of oil and 435K mcf of gas since June 2006, last reporting in July 2026. The leases carry 2 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.
