Conoco-Dean Unit #156 (API 42-079-32591) is a well in Cochran County operated by R2q Operating LLC, completed July 25, 1991 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 25, 1991, permitted to 5,250 ft.
It was permitted by Conoco Inc. and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Santa Rosa, Yates, San Andres.
Its lease has reported 2.31M barrels of oil and 1.14M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 152 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 9.52K barrels injected in the 12 months reported through December 2025.
