East Cowden (Grayburg) Unit #96 (API 42-135-38323) is a well in Ector County operated by Basin Oil & Gas Operating LLC, completed October 19, 2011 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued January 17, 2003, permitted to 4,800 ft.

It was permitted by Encore Operating, L.P. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Queen, Grayburg.

Its lease has reported 10.4M barrels of oil and 3.6M mcf of gas since January 1993, last reporting in July 2026. The lease carries 92 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 237K barrels injected in the 12 months reported through November 2025.
