Pegasus Spraberry Unit #110 (API 42-329-01045) is a plugged well in Midland County, plugged November 5, 2019, last operated by Cog Operating LLC.

The RRC has issued 2 drilling permits between 1987 and 1994, permitted to 11,870 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 6 formation tops, including Spraberry, Wolfcamp, Pennsylvanian, Devonian.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
