Pauline #1
Upton County · Spraberry (Trend Area) field · Producing · Vertical
Pauline #1 (API 42-461-34454) is a well in Upton County operated by Cog Operating LLC, completed July 11, 2005 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 10, 2003, permitted to 10,150 ft.
It was permitted by Henry Petroleum LP and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 249K barrels of oil and 1.09M mcf of gas since January 2004, last reporting volume in April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 16, 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.
