Pegasus Pennsylvanian Unit #2502 (API 42-461-03363) is a well in Upton County operated by Cog Operating LLC, completed August 1, 2002.

The RRC has issued one drilling permit, issued March 27, 2002, permitted to 13,340 ft.

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

Completion filings report 6 formation tops, including Wolfcamp, Pennsylvanian, Devonian, Fusselman.

Its 3 leases have reported 6.19M barrels of oil and 66.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 234 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.
