Participants will learn some of the standard techniques for predicting fluid flow effects in deformed rocks, along with leading-edge ideas related to the reactive reservoir concept. Attendees should learn new approaches to managing structurally-complex reservoirs.

Participants will gain most from the course if they have previously had some training in rock mechanics or experience in reservoir management. However, people without this background, but who have a broad industrial experience-base, can also benefit from the course.

Geoscientists and Reservoir Engineers who have an interest in learning how things work, and how to develop better management plans that take account of the natural and induced reactivity of hydrocarbon reservoirs.
