Petroleum Geology for Early Career Geoscientists and Engineers - PGGE

This course focuses on the key geoscience concepts that underpin oil and gas field development and reservoir management. Concepts of depositional systems and stratigraphic variability are illustrated through a combination of lectures, classroom exercises and outcrop examples of typical sandstone reservoir rocks. These concepts are placed in the context of field appraisal, development planning and reservoir management, emphasizing those geoscience topics that are critical to understanding other integrated petroleum engineering disciplines. The course describes the geological controls on reservoir characteristics, including rock properties, fluid saturation distribution and reservoir heterogeneities. The reservoir geology of the nearby coastal outcrops is compared to genetically analogous reservoirs in the North Sea and nearby Wessex basin and implications for understanding reservoir behavior are reviewed. Reservoir characteristics are related to awareness level construction of static geo-cellular models, dynamic flow models, development plans, production forecasts and the workflows of integrated field development teams. The course is intended to integrate geoscience at a level appropriate for subsurface engineers at a cross-discipline level.

Petroleum engineers and production engineers with 0 to 5 years of experience who have a limited understanding of the geoscience concepts and methods used to evaluate reservoir rocks and predict fluid flow behavior during production. Junior level geoscientists, or those new to the NW European petroleum provinces will also benefit.
