Abstract

DIGITAL ROCK PHYSICS (DRP) is a newly developed method to numerically compute rock physical properties such as permeability, elastic moduli and formation factor using high-resolution 3D images of rock sample. These images are acquired using high technology mCT-scanners which are not widely available. Imaging by this technique is also expensive and time consuming. However, improvement of 3D RECONSTRUCTION algorithms such as CCSIM reconstruction method made it possible to be used effectively as an alternative strategy in DRP. In this paper, we propose an alternative procedure described as follow: 1. high-resolution 2D imaging, 2. dividing the image to some sub-images, 3.3D reconstructing of subsamples, 4. segmentation of porosity and mineral phases and, 5. computing of rock physical parameters. This method was implemented BEREA SANDSTONE formation. Obtained results show that, in one hand, average values of sub-samples properties follow a consistent trend with the reference trends of the rock sample. On the other hand, these trends pass the results presented by a previous work. Permeability results, however, show bi-trending. Investigation in sub-images revealed that there are two types of pore shape and pore throat size. To overcome this problem, 2D image were resampled and more representative sub-images were generated. According to these results, it can be concluded that this is a valid method where an alternative method for standard DRP.
