Klotzman #4 (API 42-123-32605) is a horizontal well in De Witt County operated by Verdun Oil & Gas LLC, completed May 30, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 10, 2011, permitted to 12,220 ft.
It was permitted by Rosetta Resources Operating LP and has since transferred to Verdun Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 5.1M barrels of oil and 11.9M mcf of gas since October 2011, last reporting volume in April 2026. The lease carries 18 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 18, 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.
