Reservoir engineering has been defined as “the art of developing and producing oil and gas fluids in such a manner as to obtain a high economic recovery” (Moore, 1955).The objective of reservoir engineering is to optimise hydrocarbon recovery. This course will introduce basic reservoir engineering concepts and methods to enable cross-disciplinary teams to work productively together. The course will help understanding questions crucial to the reservoir engineer: How much oil & gas is there (accumulation)? How much can be recovered (reserves)? How fast can it be recovered (rate)? The participants will also work practical problems to ensure a thorough understanding of the principles and procedures.
