Abstract: This paper discusses the feasibility of applying a third generation medical X-ray computerized tomography(CT)scanner to the determination of porosity and oil saturation of cores. The porosities and oil saturations of eight core samples are determined with CT method and the results correspond with conventional method. A set of core analysis met hods is developed by using medical CT scanner as well as a special software package. The problems and limitations of this method are described and the ways to solve the problems are given. The significance of this study and CT analysis of a core from reservoir are presented and method of determination of core porosity is given.
