Amacker48 #3 (API 42-461-35330) is a well in Upton County operated by Cog Operating LLC, completed August 4, 2007 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued April 17, 2007, permitted to 10,800 ft.

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

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 497K barrels of oil and 2.64M mcf of gas since August 2006, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
