Abstract
Geophysical methods are used to obtain physical properties of the subsurface, by inverting the constitutive equations. If there exists a common set of rock properties (cross-properties) that influence different measurements, their joint utilization can reduce the ambiguities of the interpretation. We select a real test case in a reservoir scenario, and we explore how to determine rock porosity and fluids saturation from P-velocity, conductivity and density of the equivalent compound medium.File in questo prodotto:
