Mayer Edwin S. JR. #1402 (API 42-435-34552) is a well in Sutton County operated by Upp Operating LLC, completed March 15, 1996 and listed as producing on the RRC schedule, shut in October 1, 2020.

The RRC has issued one drilling permit (amended once), issued October 24, 1995, permitted to 8,100 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 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.

Its 2 leases have reported 92 barrels of oil and 112K mcf of gas since November 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.
