Who should attend?

Reservoir engineers, EOR engineers, production engineers, petroleum engineers, geologist, project engineers, project managers and anyone else who desire to obtain a comprehensive knowledge of CO2-EOR projects.

About the course

CO2-Enhanced oil recovery (EOR) projects involve significant risks due to additional capital and operating costs for purchasing and recycling CO2, new wells, equipment, and fluid handling/treatment to mitigate corrosion/ hydrate issues. It follows that they be optimally screened, designed and operated to reduce the overall risks. This five-day course discusses various steps involved in development of an EOR project. These steps include screening, laboratory and field testing, simulation, design, interpretation and follow-up of CO2-EOR field pilots including appropriate monitoring/ surveillance, installation of CO2 recycling (separation, dehydration & compression) facilities and critical reviews of unresolved issues in the proposed projects.
