Not one formation; the well must be completed in one of them, and no target formation is stated.

Mayer 3 #5 (API 42-435-36123) is a well in Sutton County operated by Upp Operating LLC, completed February 18, 2003 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit, issued December 12, 2002, permitted to 8,450 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 80 barrels of oil and 238K mcf of gas since February 2003, 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.
