Neal Ranch 57 #1 (API 42-461-34843) is a well in Upton County operated by Cog Operating LLC, completed September 1, 2005 and listed as shut in on the RRC schedule, shut in February 1, 2026.

The RRC has issued one drilling permit, issued May 5, 2005, permitted to 10,742 ft.

It was permitted by Terrace Petroleum Corporation and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Clear Fork, Spraberry, Jo Mill, Dean.

Its lease has reported 1.07M barrels of oil and 2.66M mcf of gas since July 2005, last reporting volume in April 2026. The lease carries 16 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.
