Who should attend?
Reservoir engineers, geologists, petrophysicists, geophysicists, petroleum engineers, production engineers, project engineers, project managers and anyone else who desire to obtain a comprehensive knowledge of integrated reservoir characterization and modeling.
About the course
A successful exploration and exploitation project requires efficient use of an integrated, multi-disciplinary team. This training course examines how such a team should be structured, what questions should be asked of each member and what tasks each should perform to deliver the answers. It addresses the different requirements of conventional plays, tight gas plays, and resources plays. Several different field examples will be used, with one public domain data set used as a common characterization theme through all modules.
You will learn
- Differentiate the contributions of a geologist, petrophysicist, geophysicist and reservoir engineer to a reservoir characterization project
- Establish the geological, petrophysical, geophysical and engineering data required to initiate a reservoir characterization project
- Determine which questions need to be answered and thus what tasks performed by each member of an integrated team
- Generate workflows for characterization of a conventional reservoir, tight gas reservoirs, and shale gas or shale oil reservoirs.
