Drillcore scanning services - Hylogger

A drillcore imaging and spectroscopic scanning service is available to industry. It uses the CSIRO-developed HyLogger™, which has special purpose automated core-logging technology. The Spectral Geologist (TSG™) software generates digital images, surface profiles and mineralogical interpretations.

The HyLogger™ was provided to the Geological Survey of NSW (GSNSW) under the AuScope National Virtual Core Library (NVCL) project and is housed at the W B Clarke Geoscience Centre in Londonderry.

The HyLogger™ system acquires information on rock, ore and alteration minerals in drillcore, chips and pulps that are often difficult or impossible for the human eye to interpret correctly. Reflected light from the samples is broken into hundreds of different wavelengths by several spectrometers, allowing the recognition of unique spectral signatures for each mineral.

This technology is also used on cores from petroleum and carbon dioxide (CO2) geosequestration wells to obtain mineralogical data that may complement porosity and permeability studies.

X-ray diffraction and X-ray fluorescence instruments are used for rapid characterisation of a wide range of geological materials and for validating HyLogger™ data.

The GSNSW offers a number of HyLogger™ scanning services to industry and academia. Each service requires a level of investment by the client and offers different periods of confidentiality.
