The RRC has issued one drilling permit, issued September 5, 2008, permitted to 5,475 ft.

It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Sydri Operating LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Cox, Bruhlmeyer, Hudspeth, Walnut.

Its 2 leases have reported 8.16M barrels of oil and 1.91M mcf of gas since January 1993, last reporting in July 2026. The leases carry 427 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.
