The course covers classical EoS modeling using an equation of state (EoS) as well as modeling of the solid phases to be taken into consideration in flow assurance studies.

The participants will learn how quality check and characterize a reservoir fluid composition for use in equation of state (EoS) modeling, and how to tune EoS model parameters to achieve a good match experimental PVT data.

It will be shown how an EoS model developed for a water free petroleum reservoir fluid can be extended to handle water and other polar components, including hydrate inhibitors. Modeling of gas hydrates, wax and asphaltenes are other topics to be covered in this 5-day course.

The course participants will be introduced to Automated QC and Automated EoS model development. Those are features introduced in PVTsim Nova to decrease the time required to generate an EoS model.

At the end of the course there is a case study enabling the participants to familiarize with Calsep’s wax deposition simulator, DepoWax.

The following topics will be covered:

Fluid handling

  • QC of fluid compositions
  • Recombination
  • Equations of State
  • C7+ characterization and lumping

PVT modeling

  • Classical PVT experiments
  • Viscosity models and Non-Newtonian viscosities
  • Regression to PVT and viscosity data

PVTsim Nova Apps

  • Automated QC
  • Automated EoS

Common EoS modeling

  • One EoS model for multiple fluids

Polar components

  • Handling of mixtures with aqueous components
  • Water, Salts, Hydrate Inhibitors

Precipitation of solids

  • Modeling of hydrate, asphaltene, wax and wax deposition

Input to simulators

  • Input for external simulators
  • Compositional simulators: OLGA, LedaFlow, HYSYS, etc.
  • Table based simulators: OLGA, LedaFlow, Pipesim, etc.

Who Should Participate

Flow assurance and process engineers who would like to make optimum use of PVTsim Nova in simulations where a proper handling of aqueous and solid phases is important.
