Midland County · Parks (Consolidated) field · Shut In · Vertical
Haley C. B. -A- #4 (API 42-329-10367) is a well in Midland County operated by Cog Operating LLC, completed September 22, 1995 and listed as shut in on the RRC schedule, shut in May 1, 2025.
The RRC has issued 3 drilling permits between 1983 and 1995, permitted to 11,975 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Spraberry, Dean, Strawn, Bend.
Its 4 leases have reported 175K barrels of oil and 373K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
