Simmons Ranch #67 (API 42-435-36634) is a well in Sutton County operated by Upp Operating LLC, completed February 13, 2004 and listed as swr-10-well on the RRC schedule, shut in October 1, 2018.
The RRC has issued one drilling permit, issued January 12, 2004, permitted to 8,200 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 26 barrels of oil and 148K mcf of gas since February 2004, with no volume in the three years through April 2026. 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 Jul 25, 2007. 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.
