Upton County · Pegasus (Devonian) field · Producing · Vertical
Pegasus Field Unit #3 #4102 (API 42-461-03321) is a well in Upton County operated by Xto Energy Inc., completed November 6, 1995 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 22, 1995, permitted to 13,325 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Spraberry, Wolfcamp, Pennsylvanian, Devonian.
Its 2 leases have reported 4.03M barrels of oil and 39M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 95 wells, so these are lease totals, not this well alone.
