Brown/Whitehead 2 #21 (API 42-435-36946) is a well in Sutton County operated by Upp Operating LLC, completed August 18, 2004 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 23, 2004, permitted to 9,100 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 94K mcf of gas since August 2004, last reporting volume in March 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
