Martin County · Spraberry (Trend Area) field · Producing · Vertical
Hale 36 #1 (API 42-317-36439) is a well in Martin County operated by Red Highland Resources LLC, completed March 26, 2011 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2010 and 2016, permitted to 10,869 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Red Highland Resources LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Strawn, Mississippian.
Its lease has reported 118K barrels of oil and 551K mcf of gas since March 2011, last reporting volume in 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 Apr 23, 2012. 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.
