Cowden E. W. #63
Winkler County · Halley field · Shut IN · Vertical
Cowden E. W. #63 (API 42-495-32309) is a well in Winkler County operated by Heifer Production Company LLC, completed March 31, 1990 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued January 8, 1990, permitted to 3,200 ft.
It was permitted by Thomas, J. C. and has since transferred to Heifer Production Company LLC on the wellbore schedule.
Completion filings report one formation top, including Yates.
Its lease has reported 412K barrels of oil and 570K mcf of gas since January 1993, last reporting in July 2026. The lease carries 53 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
Operator of record
Permitted by Thomas, J. C.; the EWA schedule now lists a different operator.
