Abstract: A method for generating a petrophysical model of a reservoir includes: selecting a depositional environment; modeling a sedimentation process in the depositional environment to produce a pore-scale model of a rock matrix of the reservoir having a lithology and facies of sedimentary rock; validating the pore-scale model using a core sample and/or known geological information to provide a validated pore-scale model; modeling the reservoir with the validated pore-scale model saturated with one or more selected fluids; upscaling one or more physical properties of the validated pore-scale model saturated with the one or more selected fluids to dimensions at which at least one macro-scale property can be measured by a downhole tool to provide an upscaled model having one or more macro-scale properties; and validating the upscaled model using the at least one macro-scale property measured by the downhole tool to provide the petrophysical model of the reservoir.

Abstract: An apparatus having transmitter and receiver antennas is provided for measuring conductivity of an earth formation surrounding a borehole. The apparatus utilizes an initial model to invert induction measurements of the earth formation to provide a conductivity model that includes a plurality of coaxial cylinders.

Abstract: Measurements made with an induction logging tool are processed to provide a resistivity model of fluid invasion of the formation. Up to five zones can be determined over a radial distance of about 0.6 m. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
