Pegasus Pennsylvanian Unit #2304
Upton County · Pegasus (Pennsylvanian) field · Vertical
Pegasus Pennsylvanian Unit #2304 (API 42-461-01077) is a plugged well in Upton County, plugged November 24, 1998, last operated by Cog Operating LLC.
The RRC has issued one drilling permit, issued March 26, 1992, permitted to 10,349 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 the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 99 wells, so these are lease totals, not this well alone.

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Wells named Pegasus Pennsylvanian Unit
COG Operating LLC's other wells filed under this lease name in Upton County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.
