Petroleum reservoir engineering course is designed to convey the students all the necessary information to get acquainted with reservoir engineering. Accordingly, the following topics will be discussed in detail: review of petroleum fluid properties and flow in porous media; reserve estimation using volumetric and material balance methods in gas, gas-condensate and oil reservoirs; discussion of reservoir drive mechanisms; aquifer models; decline analysis; routine and special core analysis; PVT data and equation of state modelling; single phase flow in reservoirs; introduction to well testing; introduction to reservoir modelling; introduction to reservoir recovery processes. Similarly, the following concepts will also be given, inclusive of practical applications: Darcy's Law and Applications, Concepts of permeability, Relative permeability, Capillary pressure, Wettability, Material Balance Equations for Different Types of Reservoirs and Drives, Aquifer Behaviour and Water Influx, Immiscible Displacement, Buckley-Leverett theory, Gravity-Stable Displacement, Water and Gas Injection, Coning and Cusping, Decline Curve Analysis, Reservoir and wellbore deliverability.
