Boyd Mallet Unit #85
Cochran County · Slaughter field · Shut In · Vertical
Boyd Mallet Unit #85 (API 42-079-30818) is a former disposal or injection well in Cochran County, last operated by Extex Operating Company; its UIC permit is no longer active.
The RRC has issued one drilling permit, issued October 7, 1977, permitted to 5,000 ft.
It was permitted by Amoco Production Company and has since transferred to Extex Operating Company on the wellbore schedule.
Its lease has reported 1.43M barrels of oil and 1.04M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 88 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Amoco Production Company; the EWA schedule now lists a different operator.

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.
