Spanish Trail #4711 (API 42-329-37962) is a well in Midland County operated by Cog Operating LLC, completed April 5, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 26, 2012, permitted to 12,000 ft.

It was permitted by E.G.L. Resources, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 8.27M barrels of oil and 12.6M mcf of gas since June 2008, last reporting in July 2026. The lease carries 89 wells, so these are lease totals, not this well alone.
