Rapid multiscale pore network modeling for drainage in tight sandstone

Tight sandstone possesses multiscale pores. Capturing and modeling the important pore properties into a network for drainage is challenging computationally expensive. We present method of network, which enables us to handle huge rock micro computed tomography (μCT) images with high computational efficiency minimal experimental input data. This uses micro-links represent upscaled transport micropores unresolved by image connects clusters that have topological relationships in extract connected from it. The size distribution optimized determined permeability. effects number on flow are investigated obtain robust parameter. presented validated digital core published successfully applied rapidly evaluate influence mineral components behavior two tight rocks, involves large computations. μCT both contain more than 109 voxels handled personal computer, proving potential rapidly, accurately, conveniently handling evaluating characteristics.
