Mayer Edwin S. JR. D #806 (API 42-435-34534) is a well in Sutton County operated by Upp Operating LLC, completed November 29, 1995 and listed as producing on the RRC schedule, shut in May 1, 2019.

The RRC has issued one drilling permit, issued July 18, 1995, permitted to 8,250 ft.

It was permitted by Dreyfus, Louis Natural Gas Corp and has since transferred to Upp Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Base Cretaceos, Base Cretaceous (marker), Wolfcamp, Canyon.

Its 2 leases have reported 276K mcf of gas since August 1995, with no volume in the three years through 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.
