Midland County · Pegasus (Pennsylvanian) field · Vertical
Pegasus Pennsylvanian Unit #301 (API 42-329-01070) is a plugged well in Midland County, plugged February 26, 2004, last operated by Cog Operating LLC.
The RRC has issued one drilling permit, issued May 31, 1990, permitted to 10,630 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Its lease has reported 1.9M barrels of oil and 18.7M mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 99 wells, so these are lease totals, not this well alone.
