Block 31 Unit #Q 20 (API 42-103-33946) is a well in Crane County operated by Oxy USA Eor LLC, completed November 11, 1994 and listed as shut in on the RRC schedule, shut in January 1, 1998.

The RRC has issued one drilling permit, issued July 10, 1989, permitted to 9,280 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Oxy USA Eor LLC on the wellbore schedule.

Completion filings report 14 formation tops, including Tansill, Yates, Grayburg, Glorieta.

Its lease has reported 15.2M barrels of oil and 971M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 330 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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