Cowden E. F. -40- #3 (API 42-135-33319) is a well in Ector County operated by Moss Swd LLC, completed February 10, 2009 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued February 13, 1980, permitted to 4,500 ft.
It was permitted by Petroleum Technical Services CO. and has since transferred to Moss Swd LLC on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
Its lease has reported 9.94K barrels of oil and 78.6K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 375K barrels injected in the 12 months reported through November 2025.
