... data and enhance history matching calibration. Post-processing technique using resistivity inversion model and mud filtrate resistivity allowed to calculate fractures and cleats aperture as well as porosity. Fracture and cleat properties, i.e. density, length, area, aperture and porosity, were inputs...

... increased when the sensor is passing in front of the conductive fracture. And the excess current is related to the fracture aperture by Luthi-Souhaite equation ( Luthi, 1990 ): (1) W = c A R m 2 R x o 1 − b W – fracture aperture (mm); A – excess current (µAmm/V...

... performance, so large amount of oil reserves is poorly flooded due to gas channeling through fractures. The fluid flow mechanisms in fractured models were discussed in order to improve field gas flooding efficiency. Based on the geological constrains of Tahe Oilfield, fractured models with different apertures...

...-oriented filter that produces fracture density, aperture, and porosity. The other technique is based on a transformation of image conductivity to porosity that is classified into a matrix and secondary pores to estimate their contribution to permeability. The multipore system analysis is then used...
