GEOTEK Multi-Sensor Core Loggers

Versatile, adaptable, portable, easy to operate, data acquired simultaneously and co-registered ready for your geological modelling

Loggers with four different designs, from one length of core to multiple core trays with up to a maximum of 9 different sensors

  • Key Features

    • Geochemical with pXRF elemental assays
    • Mineralogy linescanning with SpecCam 4 or point scanning with with ASD Terra Spec
    • Point magnetic susceptibility with Bartington point mag susc
    • High resolution line scan images with Geotek Geoscan V line scan camera with RGB filters to produce true independent colour separation
    • Natural colour with Munsell colour
    • α and β angles with profilometry
    • Total & natural Gamma with sum total of K U or Th or the measurement of the individual elements
    • P-Wave velocity with ARC transducers or reciprocating piston transducers
    • Non-contact resistivity to measure lithological information for grain size, permeability & tortuosity

The GEOTEK Multi-Sensor Core Logger (MSCL) systems enable a suite of petrophysical and geochemical measurements to be obtained rapidly, accurately and automatically on sediment or rock cores. The rugged nature of the equipment makes it suitable for use in remote locations in a core shed, a laboratory/repository environment or onboard survey and drilling vessels.

The MSCL systems can have a variety of sensors that can be added to or removed at any time.

The loggers accept core between 50 mm and 150 mm in diameter and up to 1.55 m in length and are designed to process a full range both hardrock and sedimentary core material.

  • MSCL-S

    The original Multi-Sensor Core Logger-standard from Geotek and is still the only commercially available tool for gathering both petrophysical and geochemical properties from core samples

    Maximum of 9 sensors acquiring data simultaineously

    • Geophysical measurements for stratigraphy and structure such as natural gamma, magnetic susceptibility, density, porosity and α and β angles
    • Geochemical determination of element assays and mineralogy with pXRF and hyperspectral
    • High resolution colour images with linescan photography on wet or dry core, 10 to 100 micron pixel size
    • Colour Spectrophotometry with Munsell colour system to visually describe the colour with the hue, lightness and relative colour purity
    • Co-location of all measurements in a waterfall plot

    Whole or fractured unlined core that is pushed through the system on stabilising core trays

    Simultaneous non-destructive quantification of rock properties in low or high resolution for hard rock or soft rock application for mining and oil & gas

  • MSCL-XYZ

    The Geotek Core workstation is designed to take multiple core trays

    Maximum of 5 sensors acquiring data simultaneously

    • Geophysical measurements for stratigraphy and structure magnetic susceptibility, α and β angles
    • Geochemical determination of element assays and mineralogy with pXRF and hyperspectral
    • High resolution colour images with linescan photography on wet or dry core, 10 to100 micron pixel size
    • Colour spectrophotometry with Munsell colour system to visually describe the colour with the hue, lightness and relative colour purity
    • Co-location of all measurements in a waterfall plot
  • MSCL-CIS

    The Core Imaging System is a cost-effective, fast, ultra high resolution linescan imaging system.

    The MSCL-CIS utilises Geotek’s high performance Geoscan V camera to produce images of up to 1000 pixels per cm over the full core width. The MSCL-CIS is capable of acquiring images from split or slabbed sediment/rock core, or whole round cores where multiple photographs at different angles can then be concatenated to produce a circumferential image. The Core Imaging System produces images in tagged image file format (TIFF) files that can be used in many other proprietary software packages.

  • MSCL-NG

    This is a stand-alone natural gamma system designed to obtain both total and full spectral natural gamma data. For high resolution and quality spectral data from sedimentary rocks the system can be configured with up to four NaI(Tl) detectors.

    DETECTORS

    The sensor comprises two to four 3″ x 3″ NaI(Tl) detectors housed in 6″ diameter lead shields. Each detector uses a NaI(Tl) crystal optically coupled to a photomultiplier tube and a Multi-Channel Analyser (MCA). Each of the detectors has a resolution of 6-8% specified at the 0.662 MeV peak of 137Cs. The data are collected by the MCAs over the energy range 0-3 MeV
