Abstract
This research is about determining the porosity of shale rock using the Digital Rock Physics method. The Digital Rock Physics method uses fiji software to process CT-Scan data of shale coreplug then segmentation and thresholding processes to determine the pores of the rock and then determine the value of rock porosity. The purpose of this research is to be able to determine the value of rock porosity more quickly and to compare the porosity results of Digital Rock Physics with the porosity results of laboratory tests. The results show that the porosity value obtained by the Digital Rock Physics method and laboratory tests has a small error value so that the Digital Rock Physics method is quite reliable.
