Patent number: 9599551Abstract: 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.Type: GrantFiled: June 9, 2012Date of Patent: March 21, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dmitry Anatolievich Koroteev, Alexander Nadeev, Dmitry Alexandrovich Korobkov, Igor Andreevich Varfolomeev
