THE COURSE

This course provides a comprehensive understanding of hydrocarbon fluid phase
behavior and how to model it for reservoir engineering applications. The course
begins with a thorough introduction to PVT data, including how the data is measured,
how to select the correct data for modeling, and how to enter that data in PVTsim.
The introduction to PVT data also trains participants in discovering and handling data
inconsistencies.

The course covers EoS modeling from the stage of sampling until export of the final
EoS model to a reservoir simulator or other third-party software. The aim of the
course is to provide knowledge of how to best make use of the experimental PVT
data (both routine and EOR) to build an equation of state model for single fluid or for
multiple fluids.

It will be demonstrated how to reduce the time spent on EoS modeling by making
use of PVTsim’s automated options for quality check and regression to PVT data.
The course will be presented in lectures and demonstrations coupled with hands-on
exercises in the use of PVTsim Nova.

The course will cover all key elements of PVT simulations including:
Fluid Sampling and PVT report
 Bottom-hole sample vs Separator Sample
 Compositional Analysis performed by the lab
 Extended GC
 Navigating a PVT lab report
 Selection of data to input in PVTsim

Fluid handling
 Input to PVTsim

 QC of fluid compositions
 Recombination
 Equations of State
 C7+ characterization and lumping
 Clean for oil-based mud contamination

PVT experiments
 Classical PVT experiments
 PVT experiments with gas injection (EOR)
 Separator correction for lab data

PVTsim Nova Apps
 Automated QC and EoS
 Separation process modeling

PVT modeling
 Regression to routine PVT data
 Viscosity models and regression to viscosity data
 Regression to gas injection EOR data
 Recommended workflow for EoS modeling in PVTsim

Applications
 Single fluid EoS model
 Common EoS modeling for multiple fluids sampled from the same well/field
 Compositional variation with depth
 Fluid communication study
Input to simulators
 Black oil simulators: Eclipse, IMEX, VIP, Nexus, tNavigator, Prosper/MBAL
etc.

 Compositional simulators: Eclipse, GEM, VIP Nexus, tNavigator, Prosper etc.
 Other: Multiphase Meter input

WHO SHOULD PARTICIPATE
Engineers engaged in reservoir simulations, production engineers, laboratory staff
and others interested in applying PVT simulation software for calculation of oil and
gas phase behavior and fluid properties. With its mix of theory and practice the
course is appropriate for those who want to learn to use PVTsim as well as those
mainly interested in PVT simulation methods.
