    Rock Typing and the Reservoir Characterisation

    Rock Typing is a method of classifying facies according to their similarities of porosity and permeabilities whilst honouring the nature of their depositional processes and diagenetic fabric. An ideal rock type can be integrated into a static geological model and ultimately be used in reservoir simulation and predicting fluid flows. Obviously, with such an important step in the reservoir characterisation chain it is necessary to understand the different rock typing methods and which one would be ideal for either a clastic or carbonate depositional environment. This course aims to define nomenclature and describe the different rock typing methods.
