Koval Y. Methodological fundamentals of enhancing the efficiency of determining gas saturation of complex-built reservoir rocks according to the well logging data

Object of research - lower coal deposits Timofeevskaya and Kulychyhynske gas condensate fields, upper coal deposits Rozpashnivske gas condensate field Dnieper-Donets basin and Miocene sediments Bohorodchanske gas field Carpathian oil and gas region. Purpose - development of methodological bases of processing and interpreting geophysical data which will increase the accuracy of determining the gas saturation coefficient of complex-built reservoir rocks. Methods of investigation - statistical processing of results of laboratory research of core samples and borehole geophysical research of the productive intervals. Analysis of theoretical and experimental models of petrophysical parameters of productive deposits. Theoretical modeling electric and neutron properties of rocks. The degree of implementation - results of the work successfully implemented in the area and fields of Ukraine section of witch are full of complex-built reservoir rocks. The practical application of scientific results will help significantly improve the accuracy of the gas saturation coefficient of monomiktovi not clay, polymiktovi clay sandstones and reservoir rocks with the mixed type of cement. Areas of use - oil and gas direction, its geological and geophysical companies.
