Irion County · Spraberry (Trend Area) field · Producing · Vertical
Concho #1 (API 42-235-34274) is a well in Irion County operated by Discovery Natural Resources LLC, completed October 25, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 30, 2008, permitted to 8,925 ft.
It was permitted by Fivestones Energy LLC and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 1.03M barrels of oil and 8.8M mcf of gas since October 2008, last reporting volume in April 2026. The lease carries 34 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 23, 2009. 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.
