Spanish Trail #4702 (API 42-329-35884) is a well in Midland County operated by Cog Operating LLC, completed June 15, 2008 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 10, 2008, permitted to 11,193 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 5 formation tops, including Leonard, Dean, Wolfcamp, Strawn.

Its lease has reported 8.27M barrels of oil and 12.6M mcf of gas since June 2008, last reporting volume in April 2026. The lease carries 89 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 May 5, 2011. 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.
