Cochran County · Slaughter field · Vertical

Mallet Unit #1148 (API 42-079-32615) is a plugged well in Cochran County, plugged April 24, 2023, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued August 12, 1991, permitted to 5,200 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 2 formation tops, including San Andres, Slaughter.

Its lease has reported 25.1M barrels of oil and 40.1M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 352 wells, so these are lease totals, not this well alone.
