Course Examples - Integrated Geochemical Interpretation Limited IGI Ltd

IGI offers generic courses on a multi-client basis that are designed to incorporate a whole range of disciplines from the basic theory of geochemistry and basin modelling to advanced issues to help the geologist and geochemist to develop their interpretive skills and understanding of the subsurface.

Such courses are typically of 3 or 5 day duration, and can focus on geochemical processes such as source rock deposition & maturation, petroleum generation & expulsion, and finally migration, entrapment and survival.  Alternatively, the subject can be addressed from an analytical viewpoint, starting with the design of an analytical programme for a proposed well through to interpretation of top-end molecular geochemistry data.
