Denver Unit #3SD (API 42-165-33658) is a well in Gaines County operated by Occidental Permian Ltd., completed August 22, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued July 10, 1987, permitted to 11,650 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 14 formation tops, including Yates, Seven Rivers, Queen, San Andres.

Its lease has reported 352M barrels of oil and 1.17B mcf of gas since January 1993, last reporting in July 2026. The lease carries 2,471 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 740K barrels injected in the 12 months reported through September 2025.

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