 CT Systems are based on robust Picker PQ2000 and PQS scanner technology. The rock properties applications for CT scanning include viewing full-diameter core sections (1 m or 3 ft) contained in opaque inner barrel or inner barrel liner materials to determine slabbing cut orientation relative to bedding. Applications also include identifying specific, "non-damaged", full-diameter sections to facilitate sampling site selection, detailed density studies for highly interbedded intervals, depth matching and density log comparisons.
Additionally, the CT systems are typically used for quality assessment of prepared plug samples prior to specialized core testing, saturation profiling in conjunction with flow studies and fracture analysis.
Images acquired on the UNIX-based measurements system are fed via a DICOM interface to a PC workstation where they can be easily viewed, manipulated, re -formatted and saved in TIFF or JPEG file format.
