Reservoir Fluid Properties is an undergraduate level course introduces relevant aspects of petroleum fluid properties to the university students seeking Bachelor degree B.Sc. in petroleum engineering. Reservoir fluid properties provides students with a fundamental background on the determination and evaluation of fluid properties. It also provides mathematical tools for the analysis and interpretation of data. Additionally, reservoir fluid lad helps student having physical sense of expermıntal measurements for some of hydracrbon propertıes such as density, viscosity, vapour pressure, and formation water resisitivity.
