Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.

West Ranch #2502 (API 42-371-37380) is a well in Pecos County operated by Longfellow Energy LP, completed October 20, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 15, 2004, permitted to 7,732 ft.

It was permitted by Riata Energy, Inc. and has since transferred to Longfellow Energy LP on the wellbore schedule.

Completion filings report 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Tesnus, Caballos.

Its lease has reported 73K barrels of oil and 588K mcf of gas since May 2007, last reporting volume in March 2026. The lease carries 10 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

1 log loaded from the RRC's log index, the latest received Oct 5, 2018. 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.
