Neal Ranch 56 #1 (API 42-461-35765) is a well in Upton County operated by Cog Operating LLC, completed October 3, 2009 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued April 8, 2008, permitted to 10,800 ft.
It was permitted by Terrace Petroleum Corporation and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 565K barrels of oil and 980K mcf of gas since September 2008, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
