Not one formation; the well must be completed in one of them, and no target formation is stated.

Brown/Whitehead 2 #18 (API 42-435-36550) is a well in Sutton County operated by Upp Operating LLC, completed January 21, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 7, 2003, permitted to 9,250 ft.

It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Upp Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.

Its 2 leases have reported 90 barrels of oil and 277K mcf of gas since January 2004, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

2 logs loaded from the RRC's log index, the latest received Jun 5, 2007. Density, Gamma ray, Neutron, Resistivity, Temperature. 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.
