Water flooding has long been proven as the simplest and the lowest cost approach to maintaining production and increasing oil recovery from an oil reservoir. However, these benefits may fall far short of the expectations unless the time-tested concepts and practices are clearly understood and judiciously implemented. These concepts and practices aim at process optimization —reducing production cost while minimizing waste and maximizing oil recovery and income. This course is light on theory but heavy on proven and successful practices. Published case histories of projects around the world are reviewed to provide an understanding of divergent points-of-view, what works where, what fails when, and why. This training covers all elements of a waterflood project from A to Z—from source water selection to produced water disposal and everything in between. Participants are grouped into small multi-disciplinary teams. All classroom discussions and problem-solving sessions are handled in an asset-management team format. Simulation studies are done in class to evaluate basic water flooding physics as well as to optimize the development of a hypothetical field.
Participants will learn to:
- Distinguish rock characteristics and fluid properties that control displacement of oil and thereby influence oil recovery
- Predict incremental oil recovery and develop production profile using required data and its sources
- Specify components of a well-designed water flood plan
- Estimate injection water requirement, incremental oil production, and volumes of produced water
- Monitor water flood performance and identify ways to optimize oil recovery
- Use reservoir simulation to address basic recovery mechanisms and optimization
