Black Mamba 1-57 #1
Loving County · Two Georges (Bone Spring) field · Producing · Horizontal
Black Mamba 1-57 #1 (API 42-301-31700) is a horizontal well in Loving County operated by Trp Operating LLC, completed May 16, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 3, 2012, permitted to 10,813 ft.
It was permitted by Energen Resources Corporation and has since transferred to Trp Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Bone Spring, Lower B Sand, Wolfcamp.
Its lease has reported 1.09M barrels of oil and 2.96M mcf of gas since May 2012, last reporting volume in April 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Mar 7, 2016. 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.
