Mineral, Geological, Hydrogeological, Geotechnical Explorations
During drilling:
Recording of drilling parameters vs depth (M.W.D.)
Processing of recorded data

After drilling:
Optical and acoustic borehole imaging
Delayed, nuclear, electrical, sonic, hydraulic logging, borehole geometry

During drilling :

The PocketLIM Drilling version records the drilling parameters in real time as a function of the depth. This method makes it possible to differentiate the geological layers and to target desired geological levels.

The data files are uploaded to the cloud and automatically preprocessed with the LIM @ mail web application.

The interpretation of the results and the layout of the reports are carried out with GEO-LOG 4.

After drilling :

Borehole imaging is a technique that is carried out with dedicated logging probes, in an uncased borehole to capture an “image” of the walls of the hole allowing, after processing this information, to have elements concerning the geology, lithology and / or the drilled through discontinuities.

Optical imaging (OPTV probe) is performed in a borehole that is

clean, dry or filled with clear water. It makes it possible to have a

complete in-situ visual assessment of the borehole wall and to

provide a structural model after processing.

Acoustic imaging (BHTV probe) applies to boreholes filled with

turbid fluid. It produces two images, the image of the transit times to

determine the drilling profile and the image of the amplitude of the

acoustic reflection in relation to the hardness of the rock.

Borehole logging is a technique which measures, using different probes, the characteristics of the drilled through grounds.

The data is visualized and recorded on the surface with the eMindLogger;

The probes are connected by cable to the surface via logging winches.
