This course introduces participants to established principles of modern core analysis including advanced imaging techniques. The procedures and tools for core retrieval and analysis are reviewed along with their optimal use and the uncertainty in the measurements they provide. Covered in the course is the complete handling of the core and its measurements. These extend from sample selection, data acquisition and quality control to analysis, reporting, simple modelling and integration.
Course Structure: 4 hours per day, 3 days Each day will consist of 2 modules of 2 hours each with multiple breaks.
Course Level: Foundation / Skill Duration: 3 days Instructor: Jim Funk
