Cores logged in cooperation with Advanced Geomechanics

The Geotek MSCL-S/MSCL-XCT 20' container was sent to Advanced Geomechanics in Perth, Australia, where the machines are being used to log carbonate-bearing sediments from Australian waters. The MSCL-S, with gamma density, P-wave velocity, magnetic susceptibility, and electrical resistivity is being used on both whole plastic-lined cores and steel Shelby-type push samplers (gamma density only). Whole plastic-lined cores are then imaged in the MSCL-XCT before being slabbed and re-imaged for the highest possible resolution images (about 100 micron pixel size--MSCL-XCT examples ).

Peter and Melanie visited the setup in November 2011 to upgrade the X-ray system to full computed tomography capability. The 3-D reconstructions of shell-filled carbonate cores provided evidence of how well the system is working.

Below is a multiplanar reconstruction through the two shells, along the line to the left.

...and these are the cross-sections along the red lines in the multiplanar reconstruction above. Cute little projections on the right shell!
