Paper Number: SPE-192405-MS
... fracture model is built up as the reference model for all the successive procedures and comparisons. Then several flow cases (referred as scenarios) are determined according to the target simulation conditions. A global upscaling technique under multipoint flux approximation scheme is introduced to each...

...Sobol Sampling By requiring the residual and each member of {g i (x)} to be orthogonal to each other, the set of coefficients in the approximation {y i } can be calculated (6) R ( { y i } , x ) = y ^ ( x ) − y ( x ) , Where N is the order...

... Abstract The Sobel filter is a discrete differentiation operator widely used in seismic image processing algorithms for automatic fault detection and extraction. The filter approximates the local gradient by combining derivatives of the amplitude between neighbouring traces along the x, y...

Paper Number: SPE-160863-MS
... Abstract In this paper we suggest a method for a quick indication of the absolute permeability for carbonate rock using the effective medium approximation (EMA) and pore size distribution obtained from 2-D images. A pore network is built from modified cubic lattices. Instead of using the well...
