Advanced PVT & EOS Fluid Characterization
Who should attend?
Reservoir, production, or processing engineers or managers who would like to learn more about PVT & EOS fluid.
About the course
The course is prepared mainly with the job requirements of reservoir engineering and process engineering in mind, although pipeline, transportation, and refining engineers would also benefit. Prior phase behavior experience would be helpful, but not required. A full range of relevant topics will be covered, including basic thermodynamics, black-oil and EOS modeling, PVT experiments, estimation of in situ reservoir compositions, black-oil properties from an EOS, and multi-contact miscibility.
