<p>The present invention relates to a method for characterizing a reservoir on the basis of rock and fluid flow properties, such as permeability and water saturation, from microscopic core measurements of formation samples. Information derived from core measurements of each hydraulic unit can be used to provide a transformation from wireline log porosity to permeability. The relationship between porosity and permeability is established by defining a hydraulic unit characterization factor, Hc, the logarithm of which varies directly with the logarithm of porosity and the logarithm of permeability, although at a different magnitude with respect to each. The hydraulic unit characterization factor, Hc, is the product of the square of the surface area of pore volume or grain volume and an effective zoning factor, KT, which accounts for variations in formation textural parameters that affect fluid flow. <IMAGE></p> |
