Bitumen deposits in Permian sediments in the Volga-Ural region are interesting as sources of unconventional oil. The reservoir rocks in the bituminous deposits are sand and sandstone of varying degrees of strength. For the prognosis of productive areas, it is important to study the peculiarities of the composition of bitumen-containing rocks and the mechanisms of localization of oil matter in them. These processes are closely related to the conditions of formation of the surrounding rocks. We examined samples of b...

On the territory of the Volga-Ural oil and gas province in the Permian sediments are concentrated significant resources of bitumen-containing rocks, which are of interest as a source of unconventional oil. In this connection, it is very important to clarify the conditions for the formation of bituminous strata and their productive areas. High efficiency in the study of oil-bearing rocks has radio-spectroscopic methods for determining the structure of the oil deposit and the nature of its oil and bitumen saturation...

This study focuses on petrophysical characteristics of flysch sandstones in the S-8 well section, located in the western part of the Polish Outer Carpathians (southern Poland). A number of laboratory tests were performed with application of the mercury injection capillary pressure, low field nuclear magnetic resonance, X-ray diffraction and pulse decay permeability measurements. Laboratory tests results were compared with the well logging interpretation. The laboratory analyses were conducted on core samples from ...
