Nancy #2603 (API 42-461-37038) is a well in Upton County operated by Firebird Energy II LLC, completed May 3, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 18, 2010, permitted to 10,746 ft.

It was permitted by Summit Petroleum LLC and has since transferred to Firebird Energy II LLC on the wellbore schedule.

Its lease has reported 1.08M barrels of oil and 4.68M mcf of gas since December 2008, last reporting volume in April 2026. The lease carries 16 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 Feb 14, 2014. 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.
