Masten F. O. D #4
Cochran County · Levelland field · Shut IN · Vertical
Masten F. O. D #4 (API 42-079-32901) is a well in Cochran County operated by Extex Operating Company, completed August 12, 1997 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 18, 1997, permitted to 5,100 ft.
It was permitted by Parker & Parsley, Wpi Agent and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 234K barrels of oil and 652K mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
