Subsurface reservoir containing petroleum fluids
Its structure and properties are described by Depositional facies structure, Lithological facies structure and Petrophysical rock properties
One of the most popular high-level classification of the petroleum reservoirs is given by the recoverable volume (see Table 1) and permeability-viscosity (see Table 2).
