Seam B2 core record
The panel correlates Seam B2 at approximately 104–109 m in RTB 11, 107–112 m in RTS 74 and 161–165 m in RTS 06. Across those three wells the source treats it as a roughly 4–5 m banded-coal interval.
SOURCE-LED TECHNICAL READING
Geological interpretation and evidential boundary
The panel correlates Seam B2 at approximately 104–109 m in RTB 11, 107–112 m in RTS 74 and 161–165 m in RTS 06. Across those three wells the source treats it as a roughly 4–5 m banded-coal interval. In the internship report, the core photograph establishes recovered lithology and vertical order; it cannot measure continuity between boreholes. Brightness, dull bands and visible clay partings are valid core-scale descriptions, while peat composition, rank and saleable quality require the linked laboratory results. The three boreholes correlation becomes persuasive where core boundaries and depth-matched gamma–density markers reproduce the same roof–seam–floor succession; incomplete recovery, broken core and depth offsets remain competing explanations for an apparent thickness change. Where the same panel appears in the later thesis, it preserves the source history rather than adding a second independent observation.
