Cowden J. M. R/A -A- #129 (API 42-135-35002) is a plugged well in Ector County, plugged November 7, 2019, last operated by Occidental Permian Ltd..

The RRC has issued one drilling permit, issued June 7, 1985, permitted to 5,900 ft.

It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.

Completion filings report 6 formation tops, including Rustler, Yates, Grayburg, San Andres.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
