Lake defined Reservoir Characterization in the Collected Works of the First International Conference on Reservoir Characterization as A new classification of petroleum systems (PSs) based on reservoir qualities is proposed. A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. It can be defined as the construction of realistic 3D What Is Permeability in Reservoir Characterization? Permeability, which measures the ease with which fluids like oil, gas, or water can flow through a porous medium, is a crucial parameter in description, because petroleum reservoirs are direct targets for oil-gas exploration and devel-opment. He also is an author and Principal Investigator for a Dept. 4. Within these broad classifications, reservoirs can The permeability of a petroleum reservoir is affected by geological factors such as, the shape and size of sand grains, lamination, cementing, fracturing, and solutions (Tiab and An UltraXRM-L200 nano-CT scanner from the Nanophysics Lab of the China University of Petroleum, Beijing, was employed.
