Mayer Edwin S. JR. T #2 (API 42-435-36709) is a well in Sutton County operated by Upp Operating LLC, completed April 15, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 19, 2004, permitted to 8,100 ft.

It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Upp Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.

Its 2 leases have reported 73 barrels of oil and 234K mcf of gas since April 2004, last reporting volume in April 2026. The leases carry 2 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.
