Course Description
This 5-day course provides participants with an overview of rock deformation processes that is appropriate for understanding how reservoirs respond – in terms of their geohistory, and in terms of how production activities induce new geomechanical effects. The material is aimed at an advanced audience, and is designed to suit both geoscientists and engineers.
The Training Course Will Highlight ?
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.
Training Objective
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.
Target Audience
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.
Training Methods
This interactive Training will be highly interactive, with opportunities to advance your opinions and ideas and will include;
- Lectures
- Workshop & Work Presentation
- Case Studies and Practical Exercise
- Videos and General Discussions
