Upton County · Spraberry (Trend Area) field · Vertical
Caroline #309 (API 42-461-36444) is a plugged well in Upton County, plugged April 14, 2022, last operated by Xto Energy Inc..
The RRC has issued one drilling permit, issued October 28, 2009, permitted to 11,000 ft.
It was permitted by Henry Resources LLC and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including T. Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 794K barrels of oil and 1.42M mcf of gas since April 2010, with no volume in the three years through April 2026. The lease carries 15 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Apr 30, 2013. 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.
