Mallet #133 (API 42-219-35573) is a well in Hockley County operated by Hilcorp Energy Company, completed June 6, 1990 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 3, 1990, permitted to 5,100 ft.

It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report one formation top, including San Andres.

Its lease has reported 8.6M barrels of oil and 3.74M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 196 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
