Cont. Ed: Accelerated Learning Tutorial: Applied Understanding of PVT
This practical course will provide attendees with a working knowledge of Pressure Volume Temperature (PVT) and Equation of State (EOS) theory and their applications, following a path from field sampling to the lab and on to the examination of common practices and analyses used in classical and simulated reservoir engineering.
- Understand the field separation process and sampling procedures
- Identify fluid types and their phase behavior.
- Select methods of sampling at the well site location.
- Learn how to read PVT lab reports for DLE, CCE, CVD.
- Construct black oil PVT tables for volumetrics and simulation models.
- Explain why and how the Equation of State (EOS) was developed.
