Abstract

Limestone reservoir rock or carbonate rock is one of sedimentary rock which comprise calcite (CaCO3), dolomite (CaMg(CO3)2) and aragonite mineral. This carbonate rock becomes very important in carbonate reservoir because more than 50% oil reservoir and gas in the world are carbonate reservoir. But its challenge is irregularity and complexity of pore structures as well as frame which can be altered. In diagenetic process, physical parameter of carbonate rock especially permeability is depend on pore structures and frame��s mineral. Furthermore, porosity of carbonate is very dependent to the depositional condition and diagenetic process. This diagenetic affects to pore��s condition, such as filling pore mechanism with the carbonate cements and dissolve of matrix. Therefore, diagenetic process may cause the porosity of carbonate rock can have two possibilities porosity type: primary porosity (matrix porosity) and secondary porosity which formed from diagenetic process. In this paper, we would like to present various type microstructure in carbonate rock, especially from Palimanan Cirebon in Parigi Formation. Various analysis will be present, to image the pore structure condition as well as the effect of carbonate diagenetic to the pore structure, from 0,1 mm scale using thin slice to nano to micro scale using SEM (Scanning Electron Microscope). This study is very useful for fluid flow modeling and also for elastic wave propagation analysis in irregular media.
