Block 31 Unit #P 7K (API 42-103-33996) is a well in Crane County operated by Hilcorp Energy Company, completed July 17, 1990 and listed as producing on the RRC schedule, shut in August 1, 2026.

The RRC has issued one drilling permit, issued October 31, 1989, permitted to 9,100 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 4 formation tops, including Barnett, Mississippian, Woodford, Devonian.

Its 2 leases have reported 15.2M barrels of oil and 973M mcf of gas since January 1993, last reporting in July 2026. The leases carry 331 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.
