Upton County · Pegasus (Devonian) field · SWR-10-Well · Vertical
Pegasus Field Unit #3 #3902 (API 42-461-04020) is a well in Upton County operated by Xto Energy Inc., completed August 11, 1999 and listed as swr-10-well on the RRC schedule, shut in November 1, 2026.
The RRC has issued 3 drilling permits (amended once) between 1993 and 1999, permitted to 13,136 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 5 formation tops, including Spraberry, Strawn, Dedonian, Devonian.
Its 4 leases have reported 4.08M barrels of oil and 37.8M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 108 wells, so these are lease totals, not this well alone.
