May-Montgomery Unit #56 (API 42-219-33635) is a plugged horizontal well in Hockley County, plugged February 9, 2017, last operated by Hilcorp Energy Company.

The RRC has issued 4 drilling permits (amended twice) between 1980 and 1994, permitted to 5,300 ft.

It was permitted by Amoco Production Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

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

Its lease has reported 4.93M barrels of oil and 1.58M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 87 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.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
