The development of oil deposits in the Republic of Tatarstan is entering a late stage. Deposits of natural bitumen of Cheremshano-Yamashinskaya structural zone, in particular, Ashalchinskoye, Mordovo-Karmalskoye and others, were studied. For their development requires the use of active methods ? method of thermal (steam-thermal) impact. The use of method is limited by the stability conditions of its fluid seals. Fluid seals are the layers of ?lingul clay? ? deposits of the Kazanian stage. They are represented by c...

It is known that high molecular weight paraffins are responsible for the settling out of deposits of asphalts, resins, and paraffins (ARP) and the trouble of their removal. The purpose of this study was to evaluate the effeciency of narrow straight-run oil fractions by the dissolution of ARP deposits with a different composition of solid paraffins. For the experiment, two ARP samples with a solid paraffin content of 59.0% (Sample 1) and 34.2 % (Sample 2) were taken. Narrow straight-run fractions were selected as t...

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...
