Characterization of Carbonate Rocks’ Porous Space Using X-ray Microtomography

Digital Rock Physics (DRP) is a nondestructive technique that enables the rock physic properties quantification and characterization. The method is based on the x ray absorption from each material, depending on the material density and the chemical components. Tomography methods are commonly used by medicine, but their application is coming together with geosciences since their discovery. The cross sections coming from the gray scale, can be edited by many ways, depending on the study object. The sections integrations obtained by this method, allows a 3D projection by the material used. The image processing is made by computer systems to obtain qualitative and quantitative results quickly and efficiently. In this computer system can be generated graphics and animations which facilitate the sample viewing or only a selected absorption phase in the material. Through this stage develops a job that was applied to compute microtomography technique of X-ray mainly focused on the pores tortuosity study in carbonate rocks. In this way, assist in the investigation of potential reservoirs. The data obtained by this technique is integrated and compared with petrophysical analyzes in a laboratory.
