Pecos County · Yates field · Vertical
Yates I.G. #23A20 (API 42-371-04008) is a former disposal or injection well in Pecos County, last operated by Amoco Production Company; its UIC permit is no longer active.
The RRC has issued one drilling permit, issued April 4, 1994, permitted to 1,502 ft.
It was permitted by Marathon Oil Company and has since transferred to Amoco Production Company on the wellbore schedule.
Completion filings report 7 formation tops, including Base Cretaceous (marker), Smith Sand, Yates, Seven Rivers.
Its lease has reported 322M barrels of oil and 1.03B mcf of gas since January 1993, last reporting in July 2026. The lease carries 1,725 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Marathon Oil Company; the EWA schedule now lists a different operator.
