Munger Nix C Lzs #4 (API 42-003-40588) is a well in Andrews County operated by Montare Operating Ltd., completed August 15, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 21, 2008, permitted to 4,850 ft.
It was permitted by OK Arena Operating Company and has since transferred to Montare Operating Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including Rustler, Yates, Grayburg, San Andres.
Its lease has reported 99.8K barrels of oil and 43.1K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 14 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 7, 2009. 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.
