Loving County · Phantom (Wolfcamp) field · Producing · Horizontal
C.G. Ludeman B #1H (API 42-301-30278) is a horizontal well in Loving County operated by Cog Operating LLC, completed March 5, 2013 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1981 and 2012, permitted to 12,390 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 14 formation tops, including Rustler, Salado, Bell Canyon, Cherry Canyon.
Its 3 leases have reported 183K barrels of oil and 434K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 12, 2014. 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.
