Abstract
To investigate the pore evolution, a series of uniaxial compression test was conducted on an altered breccia rock was taken from Kadidia-Sigi, Sulawesi Tengah. The treatments of uniaxial compression started from natural pressure 986553.4 N/m2 then, 1415428 N/m2, 4246285 N/m2, 7077141 N/m2, 9907997 N/m2, and 11323425 N/m2. The digital image processing method was applied to record and analyze the deformation of pore and crack structure. Physical parameters of rocks are investigated to understand the fact that porous rocks are fluid storage media. The amount of fluid contained can be estimated in an outline by analyzing the pore fraction of rocks. The results are qualitative data in the form of 2D and 3D images that the pore intensity decreases and the fractures intensity increases while quantitative data in the form of physical pore parameters [porosity {ϕ(P)} is linear negatively correlated and specific surface area {SsA(P)} is polynomial negatively correlated].
