Cooper Estate #4A (API 42-475-34613) is a well in Ward County operated by Basin Oil & Gas Operating LLC, completed December 29, 1999 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 16, 1999, permitted to 6,500 ft.

It was permitted by Great Western Drlg. CO. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Delaware, Manznaita.

Its lease has reported 519K barrels of oil and 1.48M mcf of gas since May 1998, last reporting in July 2026. The lease carries 4 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.
