Leah #2 (API 42-461-34484) is a well in Upton County operated by Cog Operating LLC, completed June 3, 2005 and listed as shut in on the RRC schedule, shut in February 1, 2023.

The RRC has issued one drilling permit, issued January 22, 2004, permitted to 10,450 ft.

It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including San Andres, Clear Fork, Spraberry, Dean.

Its lease has reported 617K barrels of oil and 2.2M mcf of gas since October 2003, last reporting volume in May 2025. The lease carries 9 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.

1 log loaded from the RRC's log index, the latest received Jul 5, 2007. 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.
