This course is aimed at providing a review of theory and latest thinking for planning wells as well as reviewing how critical pressure data is used correctly in the cycle of an oilfield, from initial discovery to development of the accumulation.

The application of pressure data for CCS is also available as an option. One main focus is how the geology of a basin must be integrated in order to achieve best results.
