Ahmed T. Equations of State and PVT Analysis: Applications for Improved Reservoir Modeling

Gulf Publishing Company. 2007. 570p.
This title covers a wide range of topics related to the Pressure Volume Temperature (PVT) behaviour of complex hydrocarbon systems and documents the ability of Equations of State (EOS) in modelling their behaviour. The main objective of this book is to provide the practising engineer and engineering student with tools needed to solve problems that require a description of the PVT of hydrocarbon systems from their compositions. Because of the dramatic evolution in computational capabilities, petroleum engineers can now study such phenomena as the development of miscibility during gas injection, compositional gradient as a function of depth and the behaviour near critical hydrocarbon systems with more sophisticated EOS models.Fundamentals of Hydrocarbon Phase Behavior
