Sutton County · Sawyer (Strawn North) field · SWR-10-Well · Vertical
Nicks Gerald 8 #4 (API 42-435-39091) is a well in Sutton County operated by Upp Operating LLC, completed October 17, 2008 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit, issued September 26, 2008, permitted to 8,608 ft.
It was permitted by Highmount Expl & Prod Texas LLC 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 577 barrels of oil and 196K mcf of gas since October 2008, last reporting volume in 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 Oct 27, 2011. Density, Neutron, Resistivity. 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.
