Cowden W. F. -C- Upper R/A -B- #56 (API 42-135-33120) is a plugged well in Ector County, plugged April 5, 2007, last operated by Occidental Permian Ltd..
The RRC has issued one drilling permit, issued February 16, 1979, permitted to 4,500 ft.
It was permitted by Amoco Production CO.-Andrews and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 2 formation tops, including Grayburg, San Andres.
Its lease has reported 141K barrels of oil and 139K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
Operator of record
