Reservoir Fluid Properties:(Preparation for Reservoir Engineering & Simulation Studies)


To understand and predict the volumetric behavior of oil and gas reservoirs as a function of pressure, knowledge of the physical properties of reservoir fluids must be gained. These fluid properties are usually determined by laboratory experiments performed on samples of actual reservoir fluids.

In the absence of experimentally measured properties, it is necessary for the petroleum engineer to determine the properties from empirically derived correlations.

This 10-day course is designed to cover the advanced aspects of reservoir engineering. Theoretical concepts and equations will be presented in an effort to assist reservoir and exploitation engineers in their functions - the determination of oil and gas reserves and the maximization of hydrocarbon recovery under primary, secondary, and tertiary schemes.

Special emphasis will be placed on Oil recovery enhancement techniques, Reservoir simulation, Executing a reservoir study, and integrated modeling and treatment of uncertainties
