Midland County · Pegasus (San Andres) field  · Vertical

Pegasus San Andres Royalty Unit #28 (API 42-329-32208) is a plugged well in Midland County, plugged July 31, 2019, last operated by Cog Operating LLC.

The RRC has issued one drilling permit, issued January 31, 1990, permitted to 5,800 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Grayburg, San Andres.

Its lease has reported 1.03M barrels of oil and 154K mcf of gas since January 1993, last reporting in July 2026. The lease carries 24 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.
