Central Ownby Unit #1003W (API 42-501-33506) is a well in Yoakum County operated by Occidental Permian Ltd., completed April 1, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued May 18, 1989, permitted to 7,098 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Occidental Permian Ltd. on the wellbore schedule.

Completion filings report 7 formation tops, including Rustler, Yates, Queen, Grayburg.

Its lease has reported 12.3M barrels of oil and 2.68M mcf of gas since January 1993, last reporting in July 2026. The lease carries 156 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 22.2K barrels injected in the 12 months reported through November 2025.

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