Katz (Strawn) Unit #451 (API 42-433-34008) is a well in Stonewall County operated by Atlas Operating LLC, completed April 24, 2015 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 30, 2014, permitted to 5,345 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 13 formation tops, including Wichita-Albany, Coleman Junction, Dothan Lime - Disposal, Gunsight.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Apr 30, 2015. 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.
