Pegasus Spraberry Unit #4106 (API 42-461-03325) is a plugged well in Upton County, plugged October 21, 2022, last operated by Cog Operating LLC.

The RRC has issued one drilling permit, issued May 12, 1999, permitted to 10,666 ft.

It was permitted by Henry Petroleum Corp. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report one formation top, including Pennsylvanian.

Its 3 leases have reported 17.1M barrels of oil and 41.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 303 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.
