Cochran County · Slaughter field · Shut In · Vertical
Dean C. S. A #245 (API 42-079-32866) is a well in Cochran County operated by Hilcorp Energy Company, completed July 7, 2023 and listed as shut in on the RRC schedule, shut in July 1, 2023.
The RRC has issued one drilling permit (amended once), issued February 5, 1996, permitted to 5,105 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its lease has reported 5.35M barrels of oil and 3.74M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 236 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
