Course Description
A petroleum system comprises the crucial elements that have to work together to create a hydrocarbon bearing basin: source rock, reservoir, seal trap, migration, and the correct timing of hydrocarbon generation. Basins can have one or more successful petroleum system. One of the main ingredients in the Petroleum System Analysis is the study of hydrocarbon charge: source, burial, generation, migration, and the products oil and gas. This course discusses the various basin types in their plate tectonic context and the hydrocarbon charging system. Emphasis lies on: recognition and evaluation of source rocks, oil and gas, thermal maturity aspects, and gas – oil – source rock correlations needed to establish the Petroleum System in a basin. About 50% of the course is dedicated to lectures, the other 50% to exercises.
