PVT Simulation Course for Flow Assurance Engineers

Kuala Lumpur: 24 August 2020 - 28 August 2020

The Course

This course gives a comprehensive understanding of PVT and fluid phase behaviour for systems where solids may form. The course begins with a thorough introduction to PVT data, including how the data is measured, how to select the correct data for modelling, and how to enter that data in PVTsim. The introduction to PVT data also trains participants in discovering and handling data inconsistencies.

After the PVT data introduction follows equilibrium modelling for two phase systems (gas/liquid), which then expands to multiphase systems where water and solids are present in addition to gas and oil. Finally, the course will cover simulation of transport of wax forming fluids in multiphase (oil and gas) pipelines systems.

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 modelling workflow.

The course is a mix of presentations and demonstrations in PVTsim combined with hands-on exercises using PVTsim Nova.

The following topics will be covered
