Masten C #5 (API 42-079-32656) is a well in Cochran County operated by R2q Operating LLC, completed April 2, 1993 and listed as producing on the RRC schedule, shut in November 1, 2026.

The RRC has issued one drilling permit, issued January 21, 1993, permitted to 4,992 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 438K barrels of oil and 579K mcf of gas since February 1993, last reporting volume in April 2026. The lease carries 18 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
