Mayer Edwin S. JR. D #802 (API 42-435-34541) is a well in Sutton County operated by Upp Operating LLC, completed December 5, 1995 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 1, 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 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.

Its 2 leases have reported 44 barrels of oil and 473K mcf of gas since October 1995, 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.

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