Cochran County · Levelland field · Shut In · Vertical
Masten F. O H #4X (API 42-079-32671) is a well in Cochran County operated by R2q Operating LLC, completed April 19, 1993 and listed as shut in on the RRC schedule, shut in November 1, 2018.
The RRC has issued one drilling permit, issued February 24, 1993, permitted to 5,050 ft.
It was permitted by Parker & Parsley, Wpi Agent and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 383K barrels of oil and 355K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
