Wheeler County · Frye Ranch (Consolidated) field · Producing · Horizontal
Black Trust 49 #4H (API 42-483-33365) is a horizontal well in Wheeler County operated by Unbridled Resources LLC, completed May 11, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 22, 2011, permitted to 11,993 ft.
It was permitted by Linn Operating, Inc. and has since transferred to Unbridled Resources LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Avant Ls, Kansas City, Cleveland, Marmaton.
Its 2 leases have reported 109K barrels of oil and 1.61M mcf of gas since May 2011, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Jan 11, 2018. Density, 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.
