Structural/Geotechnical Interpretation

Borehole images (ultrasonic and optical, based on availability) are used to accomplish structural and geotechnical interpretation. It includes data manipulation, quality control and detailed processing of the images required prior to any geological interpretation. The interpretation is focused on identifying and classifying various rock features and defects which are important to understand the structural/geotechnical framework of the rock. This can include bedding, foliations, faults, and joints. These features are analysed for their orientation (corrected for magnetic declination and borehole deviation) and spacing/frequency. A 3D virtual core based on the caliper measurement and a viable borehole image will be generated and delivered as part of the study.
