Mallet Land & Cattle Company O #86 (API 42-079-32356) is a well in Cochran County operated by Amoco Production Company, completed February 21, 1989.
The RRC has issued 3 drilling permits between 1988 and 1990, permitted to 12,600 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Amoco Production Company on the wellbore schedule.
Completion filings report 13 formation tops, including Rustler, Yates, San Andres, Glorieta.
Its 3 leases have reported 1.43M barrels of oil and 1.04M mcf of gas since January 1993, last reporting in July 2026. The leases carry 88 wells, so these are lease totals, not this well alone.
