Block 31 Unit #L 5 (API 42-103-33489) is a well in Crane County operated by Oxy USA Eor LLC, completed September 12, 1984.

The RRC has issued 2 drilling permits between 1984 and 2013, permitted to 9,370 ft.

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

Completion filings report 4 formation tops, including Grayburg, 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 334 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.
