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

Mayer Ranch W 21 #2 (API 42-435-34389) is a well in Sutton County operated by Upp Operating LLC, completed December 27, 1996 and listed as temp abandoned on the RRC schedule, shut in February 1, 2008.

The RRC has issued one drilling permit, issued November 17, 1994, permitted to 8,150 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 Bae Cretaceous, Base Cretaceous (marker), Wolfcamp, Canyon.

Its 2 leases have reported 311K mcf of gas since October 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.

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