Denver Unit #5905 (API 42-501-31707) is a well in Yoakum County operated by Occidental Permian Ltd., completed October 29, 2007 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 1979 and 1995, permitted to 5,260 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 one formation top, including San Andres.

Its lease has reported 352M barrels of oil and 1.17B mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 2,471 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.
