Mahan 19 #1 (API 42-317-36840) is a well in Martin County operated by New Height Energy LLC, completed August 3, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 10, 2011, permitted to 10,882 ft.
It was permitted by Crownquest Operating, LLC and has since transferred to New Height Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Strawn, Mississippian.
Its lease has reported 118K barrels of oil and 348K mcf of gas since August 2011, last reporting volume in March 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 Jun 10, 2014. 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.
