Deford R. K. #1
Andrews County · Andrews North (Ellenburger) field · Vertical
Deford R. K. #1 (API 42-003-03604) is a well in Andrews County operated by Mobil Oil Corporation, completed June 30, 1965.
The RRC has issued one drilling permit, issued September 19, 1984, permitted to 9,200 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Mobil Oil Corporation on the wellbore schedule.
Its 3 leases have reported 136K barrels of oil and 224K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
Operator of record
