Cochran W. C. #4 (API 42-135-07640) is a plugged well in Ector County, plugged April 28, 2022, last operated by Texland Petroleum L.P..
The RRC has issued one drilling permit, issued November 1, 1989, permitted to 5,336 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Texland Petroleum L.P. on the wellbore schedule.
Completion filings report 2 formation tops, including Grayburg, Holt.
Its lease has reported 888K barrels of oil and 139K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
Operator of record
