Abstract: A method for estimating porosity of a rock sample comprises the steps of defining a total mineral content of a sample, determining relative volume fractions for each mineral and determining X-ray attenuation coefficients for the defined minerals. Then, a first X-ray attenuation coefficient for a synthetic sample combined from the same minerals with the same volume fractions but with no pores is determined. X-ray micro/nanoCT scanning of the sample is performed and a second X-ray attenuation coefficient for the rock sample is determined. Porosity can be calculated as for a sample filled with a gas, water or light hydrocarbons, so for a sample which pores are filled with heavy hydrocarbons, or other liquid/gases with X-ray attenuation coefficient comparable with X-ray attenuation coefficient for the rock sample or for the synthetic sample.

Abstract: A method for building a 3D model of a rock sample comprises performing X-ray micro/nanoCT scanning of a rock sample and obtaining its initial three-dimensional microstructure image in a gray scale. Then, an analysis of the obtained three-dimensional image of the rock sample is performed and a binarization method is selected in dependence of the image quality and properties of the rock sample. The selected binarization method is at least once applied to the obtained initial three-dimensional image of the sample. Obtained 3D binarized image represents a 3D model of the rock sample.
