In the conditions of the deterioration of the structure of reserves of conditioned oil, development of non-traditional sources of hydrocarbon raw materials is becoming one of the promising directions of increasing the resource base of hydrocarbons. The work is devoted to the identification of changes in the chemical structure and composition of super-viscous oil as a result of steam-heat treatment in the presence of mineral compounds of carbonate reservoir rocks at temperatures of 250-300°C and pressures up to 1.6...

The influence of fertilization with nitrogen (N) at doses of 40, 80, 120, 160 kg/ha and phosphorus (P) at doses of 40, 80, 120, 160 kg/ha was studied in a long-term experiment on a Haplic Phaeozems. The results obtained showed the following: the applied nitrogen doses did not significantly influence the humus content in the soil; simultaneous application of 80-160 kg/ha P and 40-160 kg/ha N generated distinctly and very significant increases in the hummus and total nitrogen content of the soil. Ammonium nitrate ca...

In model experiments, the influence of various media on the degree of transformation of kerogen of the Domanic rock in hydrothermal processes was studied. The object of the study was a sample of the rock, from the interval of depths of 1712.5-1718.5 m of the Semiluki-Bureg (Domanic) deposits of the Berezovskaya area of the Romashkinsky deposit, which is a dark gray marl alternating with limestone. The content of OM in the rock is 11.73%, according to the thermal analysis data, a significant part of which (9.56%) i...

The paramagnetic properties of core samples from the section of the reference well was investigated on the basis of a representative sample (204 samples, along 1562, 9? ? 1478,4m depth and 84,5m powerful) by electron paramagnetic resonance (EPR) for mineral associations of the Liven horizon of the Upper Devonian deposits of the Volga-Ural region of the Republic of Tatarstan. In fact, according to the results of the EPR studies, the Liven?s horizon is a continuation of the regressive cycle of calcareous deposits of...

The paramagnetic properties of core samples from the section of the reference well were performed on 62 samples (1478,1? ? 1455,3? interval) Zadon?s horizon Famennian period by electron paramagnetic resonance (EPR) for mineral associations of the of the Upper Devonian deposits of the Volga-Ural region of the Republic of Tatarstan. Thus, a complex of geochemical EPR parameters of rocks (Mn2+, Fe3+ in limestones, anionic complexes SO3, SO2, PO2, alfa = 15 * I (Mg) / I (Ca) ions Mn positions Mg / Ca in dolomite, C600...

In the East of the Russian plate oil-gas occurrences in Bashkortostan, Perm region and Udmurtia were revealed in the Vendian-Riphean sedimentary deposits. Industrial oil inflows have been obtained in a number of areas. Possible perspective intervals are associated with great depths, in particular, with the deposits of the lower Riphean. The deposits of the Lower Riphean in the territory of Bashkortostan were discovered on the Eastern-Askinskaya area. The results of a study of the material composition of rocks show...
