Upton County · Pegasus (Consolidated) field · Vertical
Txl SS #4602 (API 42-461-33092) is a plugged well in Upton County, plugged December 29, 2010, last operated by Cog Operating LLC.
The RRC has issued 2 drilling permits between 1990 and 2004, permitted to 11,000 ft.
It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including San Andres, Clear Fork, Spraberry, Dean.
Its 4 leases have reported 1.95M barrels of oil and 18.8M mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 101 wells, so these are lease totals, not this well alone.
