DMT CoreScan SystemHigh Tech Core Logging vs Conventional Core Logging


CoreScan3 Core Imaging

High resolution (up to 1016 dpi or 40 pixel/mm)

equivalent to >200 MP

360° full drill core circumferential images

No Image distortion

No light reflections on core samples

Uniform light conditions

Automated core box image segmentation



Conventional Core Photography

Low resolution (Max. <60 MP)

No 360°, only planar overview photos

Image distortion, variable angles of view

Light reflections on (wet) core samples

Light conditions depend on daylight or other

external light sources

No further core box image processing available

Original core box scan Masked core box scan

Automatically processed continuous core image profile


CoreScan3 Core Image Management

Core image orientation (360° mode) according toreference line or BH images

Generation of continuous core image depth logs Core image data base structure (CompanyLocation

DHIDCore RunCore BoxCore Image Fast search function by name, location, depth intervall

or specific features (lithology, etc.) Digital drill core library



Conventional Core Photography handling

No core orientation possible

Single core box images with no continuous depth image log

Core Box Images stored in folders

No search function

Non-structured folder storage

CoreBase2.

Right - Continuous core image depth profile.


CoreScan3 Core Logging Features

Structural analysis and derivation of geotechnicalparameters (RQD, FD, FS)

Generation of lithological columns (strip logs) Integration of core analysis (assays, geotechnical

parameters, etc.) Integration of BH data (LAS files) Visualization of high res images and additional logging data

along a continuous depth log („digital log sheet“) Compatibility with 3D modelling software



Conventional Core Logging

No core logging based on high res images.

Logging is done into defined spreadsheets

No data visualization prior to uploading into modelling
