Upton County · Pegasus (Consolidated) field · Shut In · Vertical
Pegasus Spraberry Unit #1602 (API 42-461-04285) is a well in Upton County operated by Cog Operating LLC, completed July 30, 1994 and listed as shut in on the RRC schedule, shut in May 1, 2021.
The RRC has issued 2 drilling permits between 1993 and 1994, permitted to 13,056 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Spraberry, Dean, Wolfcamp, Pennsylvanian.
Its 3 leases have reported 19.1M barrels of oil and 59.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 293 wells, so these are lease totals, not this well alone.
