Plugged

Cochran County · Slaughter field  · Vertical

Dean I #20 (API 42-079-32627) is a plugged well in Cochran County, plugged August 13, 2021, last operated by Extex Operating Company.

The RRC has issued one drilling permit (amended once), issued March 2, 1992, permitted to 5,350 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 246K barrels of oil and 112K mcf of gas since January 1993, last reporting in July 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
