Course Credit: 0.15 CEU, 1.5 PDH

In reservoir studies, from material balance calculations to simulation, fluid properties are always required to estimate in place volumes, EOR potential, and the transport parameters that interact with the flow. The variations of PVT properties during depletion phase are also needed to evaluate the reservoir performance and to design surface and subsurface facilities. In general fluid properties are central to almost all the applications in the form of input.

In recent years, rising number of offshore projects and as well unconventionals and difficult fluids have made the modeling of reservoir fluid properties even more important. Some of the frequently encountered key issues are:

1. Sampling issues (near-saturated fluids, unconventionals, contamination and quality)
2. Modeling issues (lean condensates, near critical fluids and integrated fluid characterization)
3. Kinetic aspects/diffusivity

The final goal of a successful “PVT program” is to represent/model the reservoir fluid from reservoir to refinery with a single set of adjustable parameters (modeling consistency).
