Summary
Summary
Developed in conjunction with several oil companies using experimental data for real reservoir fluids, Phase Behavior of Petroleum Reservoir Fluids introduces industry standard methods for modeling the phase behavior of petroleum reservoir fluids at different stages in the process. Keeping mathematics to a minimum, this book discusses sampling, characterization, compositional analyses, and equations of state used to simulate various pressure-volume-temperature (PVT) properties of reservoir fluids.
Featuring new figures, references, and updates throughout, this Second Edition :
Adds simulation results for PVT data obtained with the PC-SAFT equation Describes routine and EOR PVT experiments with enhanced procedural detail Expands coverage of sampling, compositional analyses, and measurement of PVT dataPhase Behavior of Petroleum Reservoir Fluids, Second Edition supplies a solid understanding of the phase behavior of the various fluids present in a petroleum reservoir, providing practical knowledge essential for achieving optimal design and cost-effective operations in a petroleum processing plant.
