Cowden E. W. -E- #1BH
Winkler County · Emperor Deep field · Vertical
Cowden E. W. -E- #1BH (API 42-495-05209) is a former disposal or injection well in Winkler County, last operated by Heifer Production Company LLC; its UIC permit is no longer active.
The RRC has issued one drilling permit, issued January 23, 1989, permitted to 3,100 ft.
It was permitted by Hillin-Simon Oil Company and has since transferred to Heifer Production Company LLC on the wellbore schedule.
Completion filings report one formation top, including Yates.
Its 3 leases have reported 64.4K barrels of oil and 338K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Hillin-Simon Oil Company; the EWA schedule now lists a different operator.
