COURSE OVERVIEW
This 5 day training is designed for upstream oil & gas production, reservoir/production engineers and geoscientists who need to understand PVT phase behavior and tests for different types of fluids (dry gas, wet gas, gas condensate, volatile oil, and black oil), how the experimental data are presented in PVT reports, identifying relevant data and how the results can be used for Equation of State (EoS) tuning and modelling. A familiarity with basic petroleum and reservoir engineering principles is a prerequisite. Topics ranging from reservoir fluid composition, phase behavior and reservoir fluids classification; optimally obtaining high quality PVT fluid samples; effect of contamination; PVT tests and correlations/modelling; density, viscosity and interfacial tension, the evaluation and application of PVT reports; fluid analysis and characterization, Equation of State (EoS) tuning using a commercial model and applications in reservoir simulation. There will be a discussion of potential causes of errors and several case studies. Considerable time will be allocated to reviewing PVT reports and extracting relevant data and using the data in tuning of EoS.
