Stonewall County · Katz (Strawn) field · Shut In · Vertical
Katz (Strawn) Unit #361 (API 42-433-33929) is a well in Stonewall County operated by Atlas Operating LLC, completed July 10, 2014 and listed as shut in on the RRC schedule, shut in December 1, 2022.
The RRC has issued one drilling permit, issued December 30, 2013, permitted to 5,350 ft.
It was permitted by Kinder Morgan Production CO LLC and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Coleman Junction, Dothan Lime - Disposal, Bend, Cambrian Sand - Disposal.
Its lease has reported 13.1M barrels of oil and 30.2M mcf of gas since May 2010, last reporting volume in March 2026. The lease carries 245 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
2 logs loaded from the RRC's log index, the latest received Feb 10, 2015. 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.
