General Objective The overall objective of this course is to deepen and strengthen the knowledge that professionals working in the Oil Industry Geosciences, should have about Stratigraphy, Sequence Stratigraphy and Sedimentology, including aspects of advanced sedimentology, like those in the source to sink systems analysis and the study of the dynamics of sedimentary environments and their recognition in the ancient record.

Emphasis will be place on fulfill the needs of reservoir characterization and quality prediction within the petroleum system.

The target level of proficiency to be obtained will be: basic to intermediate
