Southeast Luther/Fusselman/ Unit #603 (API 42-227-35930) is a well in Howard County operated by Trek Resources Inc., completed May 26, 2005 and listed as shut in on the RRC schedule, shut in January 1, 2015.

The RRC has issued one drilling permit, issued January 4, 2005, permitted to 10,125 ft.

It was permitted by Chesapeake Operating, Inc. and has since transferred to Trek Resources Inc. on the wellbore schedule.

Completion filings report 6 formation tops, including Wolfcamp, Pennsylvanian, Atoka, Woodford.

Its lease has reported 5.1M barrels of oil and 2.55M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 42 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 Sep 12, 2008. 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.
