FUNDAMENTALS OF THERMODYNAMICS • Petroleum fluids genesis. • Chemical composition of petroleum fluids: • Hydrocarbon families. • Compositional presentation of reservoir fluids. • Thermodynamics of petroleum fluids: • Pure component, binary mixture, multi-component systems. Phase behavior. • Hydrocarbon fluids: under saturated oil, saturated oil, dry gas, wet gas, retrograde gas. Phase envelope. • Measurements: • Sampling: • Bottom hole and surface sampling. • Representativity and validity of sampling. • Analysis. • PVT studies: oil - gas condensate. PROPERTIES OF HYDROCARBON FLUIDS • Thermodynamics: mixture equilibrium, fluids classification. • Liquid-vapor equilibrium: • Real equilibrium, thermodynamics potential, fugacity. • Saturation pressure, formation volume factor, density, compressibility, viscosity. • Equation of state: • Peng-Robinson, Soave-Redlich-Kwong. • Liquid-vapor calculation. • Analytical representation: properties of light and heavy cuts. • Fluid modeling: PVT matching. • Fluid synthesis: gravity segregation, field cases, miscibility. • Downstream data: data for reservoir simulator and process. PVT MODELING • Matching a PVT model to experimental data using a PVT EOS package. |
