Ector County · Cowden North (Deep) field · Producing · Vertical
Cowden J. M. R/A -A- #126 (API 42-135-35010) is a well in Ector County operated by Occidental Permian Ltd., completed December 9, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 20, 1985, permitted to 5,415 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, San Andres, Holt.
Its lease has reported 1.61M barrels of oil and 212K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 31 wells, so these are lease totals, not this well alone.
