Block 31 Unit #K 3K (API 42-103-30773) is a well in Crane County operated by Oxy USA Eor LLC, completed May 29, 1973.

The RRC has issued one drilling permit, issued September 25, 2026, permitted to 9,150 ft.

It was permitted by Hilcorp Energy Company and has since transferred to Oxy USA Eor LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Barnett, Woodford, Devonian.

Its 2 leases have reported 15.2M barrels of oil and 971M 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.
