Equipment for Mine Exploration in Kolkata

For Exploration

The drilling parameters are continuously recorded as a function of depth by the PocketLIM Drilling version. This technique enables the targeting of desired geological layers and the differentiation of the geological levels.

The LIM @ mail web application preprocesses the data files automatically after they are uploaded to the cloud.

With GEO-LOG 4, the findings are interpreted, and the reports are formatted.

After drilling:

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

Optical imaging (OPTV probe) procedure is carried out in a borehole that is clean, dry, or filled with clear water. It enables a complete in-situ visual assessment of the borehole wall and the generation of a structural model after processing.

Acoustic imaging (BHTV probe) is used in turbid fluid-filled boreholes. It generates two images: one of the transit times used to calculate the drilling profile and another of the amplitude of the acoustic reflection in relation to the hardness of the rock.

Borehole logging is a technique that uses various probes to measure the characteristics of the drilled through the ground.
