West Ranch #3111 (API 42-371-37928) is a well in Pecos County operated by Longfellow Energy LP, completed September 16, 2007 and listed as swr-10-well on the RRC schedule, shut in April 1, 2024.

The RRC has issued one drilling permit, issued May 4, 2007, permitted to 7,171 ft.

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

Completion filings report 4 formation tops, including Wolfcamp, Caballos I, Lower Caballos Ii, Lower Caballosii.

Its 2 leases have reported 1.86K barrels of oil and 1.06M mcf of gas since September 2007, last reporting volume in February 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 Jul 27, 2010. Density, Neutron, Resistivity. 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.
