Wichita County · K-M-A field · Producing · Vertical
Kempner Unit #45 (API 42-485-45431) is a well in Wichita County operated by R2q Operating LLC, completed September 6, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 2, 2013, permitted to 4,600 ft.
It was permitted by Extex Operating Company and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Ranger Limestone, Kma Lime, Ellenburger.
Its lease has reported 383K barrels of oil and 132K mcf of gas since January 1993, last reporting volume in February 2026. The lease carries 30 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 12, 2013. 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.
