Upton County · Pegasus (Consolidated) field · Producing · Vertical
Pegasus Spraberry Unit #1709 (API 42-461-01714) is a well in Upton County operated by Cog Operating LLC, completed June 30, 1994 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 10, 1994, permitted to 12,010 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 4 formation tops, including Spraberry, Wolfcamp, Pennsylvanian, Devonian.
Its 3 leases have reported 15.2M barrels of oil and 23.2M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 205 wells, so these are lease totals, not this well alone.
