Cochran County · Levelland field · Producing · Vertical
Masten F. O. #50 (API 42-079-30846) is a well in Cochran County operated by Vision Oil And Gas LLC, completed March 9, 1978 and listed as producing on the RRC schedule, shut in May 1, 2024.
The RRC has issued one drilling permit, issued February 2, 1978, permitted to 5,098 ft.
It was permitted by Monsanto 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.

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.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
