This online 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 a single fluid or for multiple fluids.

The course participants will use the Automated QC and the Automated EoS Apps which decrease the time required to generate a robust EoS model, all the while using Calsep’s recommended EoS modeling workflow.

The course, taught by experienced Calsep engineers, is a mix of presentations and demonstrations in PVTsim combined with hands-on exercises using PVTsim Nova. Participants will receive a PVTsim course certificate at the end of the course.
