Wireline & Formation Evaluation


The course is designed for engineers who are involved in the formation evaluation process, in which coring, mud logging productivity testing and wire line logging are the main components - well logs provide a comprehensive snapshoot of all the formation penetrated by a borehole. The course stresses the theory, measurements, applications and limitation of the available logging tools. Interpretation methods for rock type, litho logy, porosity and hydrocarbon saturation are reviewed.
