Pegasus Pennsylvanian Unit #1705 (API 42-461-03862) is a well in Upton County operated by Cog Operating LLC, completed September 8, 1994.
The RRC has issued 2 drilling permits between 1994 and 1998, permitted to 13,126 ft.
It was permitted by Henry Petroleum Corp. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Spraberry, Wolfcamp, Pennsylvanian, Devonian.
Its 5 leases have reported 5.82M barrels of oil and 56.2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 196 wells, so these are lease totals, not this well alone.
