Cowden A #1 (API 42-317-33554) is a well in Martin County operated by Diamondback E&P LLC, completed October 20, 1988 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 2, 1988, permitted to 9,550 ft.

It was permitted by Parker & Parsley Petroleum CO. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Spraberry, Dean.

Its lease has reported 81.2K barrels of oil and 91.3K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 2 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.
