Conoco-Dean Unit #90 (API 42-079-30178) is a disposal or injection well in Cochran County operated by Extex Operating Company under an active UIC permit.
The RRC has issued one drilling permit, issued October 11, 2005, permitted to 5,100 ft.
It was permitted by Shenandoah Petroleum Corporation and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Clear Fork, Wolfcamp.
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.
