This course focuses on methods that can be used to improve the prediction of reservoir size, shape, trend and quality through detailed analysis of depositional environments. The sedimentary characteristics of each of the Fluviatile and Deltaic depositional systems are presented in detail, using examples from recent environments, outcrops, cores, wireline logs and test/production data from oil and gas fields in various parts of the world.
