Conoco-Dean Unit #142 (API 42-079-32447) is a well in Cochran County operated by Extex Operating Company, completed March 2, 1990 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued November 20, 1989, permitted to 5,200 ft.

It was permitted by Conoco Inc. 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 2.31M barrels of oil and 1.14M mcf of gas since January 1993, last reporting in July 2026. The lease carries 152 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 76.8K barrels injected in the 12 months reported through December 2025.
