Advanced Recovery Methods
Advanced Recovery Methods - training course
The physics governing the effectiveness of various recovery methods: polymer flooding, microbial enhanced oil recovery, deep diversion technology (gels of different kinds), surfactant flooding, low salinity water flooding, gas injection, water-alternating-gas (WAG) and Foam-Assisted-WAG; is illustrated in relation to experiments and simple modeling. The methods (mechanism) and applicable conditions (simple screening criteria) are presented together with field examples if available; the course covers a staged approach to understand the potential of Advanced Recovery methods in various situations. The methodology is also illustrated with the application to different reservoir situations. The uncertainty of predictions and the economic benefit of various schemes are also discussed.
This is a three-day classroom-based course with worked examples, case studies, exercises and discussion. The course includes micro-scale examples to see practical illustrations of the important physical processes. Participants will have the opportunity to bring their own reservoir data to discuss the potential of alternative strategies.
Suitability - Who should attend?
The course is designed for mid to senior level engineers, production geoscientists and subsurface managers.
A desire to understand the basic physics of Advanced Recovery, including the treatment of economics and uncertainty is required. Familiarity with some reservoir engineering concepts and terminology is assumed.
Outcome / Qualification etc.
Participants will learn to:
- Evaluate the physics governing the effectiveness of various recovery methods.
- Appraise simple laboratory scale experiments.
- Evaluate the impact of various geological settings by reference to first order modelling assumptions.
- Screen out non-viable Advanced Recovery schemes using the binary indicator method.
- Assemble and perform analytical performance indicator screening tools.
- Evaluate the uncertainty of potential methods due to geological variability.
- Design and evaluate the economic benefit of a potential Advanced Recovery schemes.
Participants will also have gained a fundamental understanding of the physical processes of fluid-flow that underpins the approach.
