Advanced Logging Tool Operations and Evaluation

The course aims to increase the knowledge of the geologists, geophysicists and the others who are working in the field of oil and natural gas production. This course covers the whole range of special core analyses and advanced open hole tools and their applications. This is a wide-ranging course that effectively covers all the logging techniques in open boreholes. The course starts with an overview of the reservoir rock properties and reservoir fluids. This is an essential factor as a background to the various logging techniques and their interpretations. Special core analyses, dipmeter, FMI, RFT and MDT logging tool principles will also be presented. The attendees will feel that they became more professional, and know more about the geologic description and exploration of the underground rocks/reservoirs using the well logging techniques. They will be able to evaluate the reservoirs and assess their performance. The comprehensive course documentation has been designed as a useful guide for future reference.
