A tight sandstone sample has been projected with x-ray twice. First, the classic micron x-ray computed tomography images have been generated based on the dry sample. The resultant model does not provide the connectivity for permeability computations due to the large portion of sub-resolved pores. To take the effects of sub-resolved pores into account, the sample has been saturated with xenon and then projected for x-ray again. The target is to propose a hybrid digital image processing method to prepare a digital model including solids, pores and porous voxels. The prepared model then can be applied with the Stokes-Brinkman equation to compute the overall permeability of the model.
