Martin County · Spraberry (Trend Area) field · Vertical
Kemper AZ #1 (API 42-317-35591) is a plugged well in Martin County, plugged March 13, 2020, last operated by Endeavor Energy Resources L.P..
The RRC has issued one drilling permit, issued March 27, 2009, permitted to 11,000 ft.
It was permitted by RR Oil & Gas, LLC and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.
Completion filings report 4 formation tops, including Wolfcamp, Cline, Strawn, Mississippian.
Its lease has reported 34.6K barrels of oil and 422K mcf of gas since May 2009, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 14, 2012. Density, Neutron. 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.
