Cochran County · Levelland field · Shut In · Vertical
Masten F. O. #66 (API 42-079-31778) is a well in Cochran County operated by Vision Oil And Gas LLC, completed October 17, 1983 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit, issued September 7, 1983, permitted to 5,080 ft.
It was permitted by Monsanto Oil Company and has since transferred to Vision Oil And Gas LLC on the wellbore schedule.
Its lease has reported 706K barrels of oil and 1.03M mcf of gas since January 1993, last reporting volume in November 2025. The lease carries 89 wells, so these are lease totals, not this well alone.

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.
