Block 31 Unit #B 4 (API 42-103-31083) is a well in Crane County operated by Oxy USA Eor LLC, completed June 12, 1975.

The RRC has issued 2 drilling permits between 2001 and 2007, permitted to 9,350 ft.

It was permitted by BP America Production Company and has since transferred to Oxy USA Eor LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Devonian, Fusselman.

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 332 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.
