Cochran County · Levelland field · Producing · Vertical
Masten F. O. 20 #3 (API 42-079-30828) is a well in Cochran County operated by Ctoc Energy LLC, completed February 15, 1978 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 14, 1977, permitted to 5,087 ft.
It was permitted by Atlantic Richfield CO. and has since transferred to Ctoc Energy LLC on the wellbore schedule.
Its lease has reported 37.4K barrels of oil and 40.7K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
