Tycoon G Unit #1251H
Reeves County · Wolfbone (Trend Area) field · Producing · Horizontal
Tycoon G Unit #1251H (API 42-389-35235) is a horizontal well in Reeves County operated by U.S. Energy Development Corp, completed February 2, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 15, 2016, permitted to 10,531 ft.
It was permitted by Cog Operating LLC and has since transferred to U.S. Energy Development Corp on the wellbore schedule.
Completion filings report 8 formation tops, including Delaware, Castile, Bell Canyon, Cherry Canyon.
Its lease has reported 2.48M barrels of oil and 8.32M mcf of gas since January 2017, 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 19, 2020. 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.
