West Ranch #3403 (API 42-371-37286) is a well in Pecos County operated by Longfellow Energy LP, completed January 2, 2004 and listed as producing on the RRC schedule, shut in June 1, 2026.
The RRC has issued one drilling permit, issued June 13, 2003, permitted to 8,210 ft.
It was permitted by Riata Energy, Inc. and has since transferred to Longfellow Energy LP on the wellbore schedule.
Completion filings report 6 formation tops, including Base Cretaceous (marker), Wolfcamp, Dimple, Tesnus.
Its 2 leases have reported 97.7K barrels of oil and 561K mcf of gas since October 2003, last reporting volume in April 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
