Masten C #19 (API 42-079-32707) is a plugged well in Cochran County, plugged August 6, 2020, last operated by Extex Operating Company.
The RRC has issued one drilling permit, issued May 19, 1993, 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 438K barrels of oil and 579K mcf of gas since February 1993, last reporting in July 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
