...-resistance network or with the use of effective medium theory. For many cases both approaches provide similar results. The model developed in this study leads to the observation that including fracture dip and tortuosity in the petrophysical analysis can generate significant changes in the dual porosity...

... Abstract Recent models show means of estimating the petrophysical porosity exponent m of a reservoir when it is composed of different combinations of matrix, fractures and vugs. For both dual and triple porosity reservoirs, the system is modelled as a parallel resistance network (for matrix...

... Abstract One of the parameters needed to calculate in-situ water saturation from wireline logs is the resistivity of connate water, R w . It is usually determined by measuring the resistivity and chemical composition of uncontaminated connate water produced from the formation or underline...

... the feasibility of water disposal in the basal water sands of the McMurray Formation was investigated. Seismic reflection data, collected originally for oil sands delineation, was supplemented with drilling, seismic, resistivity, and borehole logging surveys to map the sand channels. Isopach maps of the basal...

... calculation of matrix porosities and true resistivities for the matrix. By placing pore throat apertures, capillary pressures and heights above the free water table on Pickett plots, it is possible to generate matrix flow units and to estimate if the matrix will contribute to production. Pattern recognition...

... of permeability. This study attempts to use electrical resistivity measurement method as an analytical tool to study how changes in grain fabric affect changes in tortuosity. The first phase of the study concentrates on development of a framework on the flow tortuosity behaviour observed in idealized granular...
