Block 31 Unit #Z 2 (API 42-103-03055) is a former disposal or injection well in Crane County, last operated by Oxy USA Eor LLC; its UIC permit is no longer active.

The RRC has issued 2 drilling permits between 2005 and 2019, permitted to 10,460 ft.

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

Completion filings report 3 formation tops, including Wolfcamp, Pennsylvanian, Devonian.

Its 4 leases have reported 16.1M barrels of oil and 976M mcf of gas since January 1993, last reporting in July 2026. The leases carry 369 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.
