Cochran County · Levelland field · Water Supply · Vertical
Masten F. O. #1WS (API 42-079-32608) is a well in Cochran County operated by Cross Timbers Energy LLC, completed August 30, 1991 and listed as water supply on the RRC schedule.
The RRC has issued one drilling permit, issued July 17, 1991, permitted to 400 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Cross Timbers Energy LLC on the wellbore schedule.
Its lease has reported 334K barrels of oil and 178K mcf of gas since January 1993, last reporting in July 2026. The lease carries 23 wells, so these are lease totals, not this well alone.
