Electrofacies — Seam A1
The internship panel compares the core-defined A1 interval across three boreholes with its wireline character. Here the diagnostic target is the seam body, including short departures from the low-gamma motif that can be tested against the documented internal partings.
SOURCE-LED TECHNICAL READING
Geological interpretation and evidential boundary
The internship panel compares the core-defined A1 interval across three boreholes with its wireline character. Here the diagnostic target is the seam body, including short departures from the low-gamma motif that can be tested against the documented internal partings. The low-gamma, broadly boxcar-to-cylindrical response is compatible with a laterally recognisable low-clastic interval, while short excursions can be checked directly against the recorded partings. Density is plotted here in counts per second; without the tool transform and calibration it is not a conventional bulk-density scale. Accordingly, curve shape is used to transfer a core-defined marker, not to name an environment: hole condition, bed thickness, mineral matter and depth registration can all modify the motif. The thesis reuses this panel within a broader synthesis; it is not independent log control.
