Wilson Duke #1725 (API 42-435-36213) is a well in Sutton County operated by Upp Operating LLC, completed February 3, 2003 and listed as swr-10-well on the RRC schedule, shut in June 1, 2025.
The RRC has issued one drilling permit (amended once), issued February 14, 2003, permitted to 8,501 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 48 barrels of oil and 293K mcf of gas since February 2003, last reporting volume in May 2025. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Aug 18, 2006. Density, Gamma ray, Neutron, Resistivity, Temperature. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
