Mayer Minnie H. D-38 #1 (API 42-435-36465) is a well in Sutton County operated by Upp Operating LLC, completed September 28, 2003 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 11, 2003, permitted to 8,115 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 28 barrels of oil and 145K mcf of gas since September 2003, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
