Abstract
Summary
Bazhenov shales were studied by scanning electron microscopy (SEM), transmission electon microscopy (TEM) focus ion beam (FIB), energy dispersive X-ray spectroscopy (EDXS) together with x-ray difraction (EDX). The pore space of the kerogen were reconstructed and the pore dimensions were estimated. It was found that these dimensions varied between 0.2 - 2 μm. The reconstruction of the kerogen areas allowed us to estimate the volume of pore space and it was about 23%, the volume of interconnected pores - 94%. Other compounds, namely clay minerals, pyrite, quarts and some other were also found in the shales by EM, EDS and XRD
