Multi-Sensor-Core-Logger (MSCL) : 9783656644859 : 25 Apr 2014 : Internship Report from the year 2013 in the subject Geography / Earth Science - Miscellaneous, grade: 2,3, RWTH Aachen University (Lehrstuhl für Geologie, Geochemie und Lagerstätten des Erdöls und der Kohle), course: Petrophysics Practical Course, language: English, abstract: The MSCL-experiment encloses the stepwise measurement of three different parameters: Gamma density, P-wave-velocity (compressional wave travel time) and magnetic susceptibility. Each is measured by different sensors. A photo of the apparatus is shown in figure 1. The four core samples G1, a black stone, coarse-grained and compacted with small mica particles and bigger white quartz inclusions, could be a gabbro and G2 a greenish sandstone with small particles and lesser compaction, each unsaturated and saturated with water are halved and "transported on a stepper motor-driven tracking system" to the sensors. If the rock sample is heterogeneous and the
