Masten Unit #2 (API 42-079-30564) is a well in Cochran County operated by Talis Energy Inc., completed February 1, 1997 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued January 4, 1978, permitted to 4,920 ft.

It was permitted by Union Oil Company Of California and has since transferred to Talis Energy Inc. on the wellbore schedule.

Its 2 leases have reported 967K barrels of oil and 3.79M mcf of gas since January 1993, last reporting in July 2026. The leases carry 66 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 4.8K barrels injected in the 12 months reported through February 2026.
