The paper presents the results of a study of the granulometric composition of terrigenous reservoir of the Nizhne-Karmalskoye super-viscous oil deposit. The main interest is a sand pack composed of weakly cemented and loose fine and medium-grained sands and sandstones. Clastic grains are mainly bonded with high-viscosity oil. the thickness of the sand pack on the deposit varies widely. The grain size of reservoir rocks has a significant impact on the reservoir properties of rocks and reservoir productivity as a wh...

Geophysical surveys of wells represent a wide range of methods, the rational integration of which make it easier the solution of geological problems. In this article, the authors investigate the issue of identifying the parameters of hydraulic fractures. This method is one of the frequently used methods for increasing well productivity. Modifications of nuclear logging and the possibility of acoustic logging are considered on the example of data before and after hydraulic fracturing in carbonate and sandstone depo...

This paper presents the results of a study of the mineral composition of rocks on the example of one of the high viscosity oil deposits. Studies were performed using X-ray diffraction analysis. Samples of both the reservoir itself, represented by bituminous sandstone, and samples of overburden and underlying formations composed of clays and limestones were studied. Samples were taken from several wells, which makes it possible to judge the variability of the mineral composition along strike. The content of clay mi...

Modeling the elastic properties of rocks may be one of the characteristics of the investigated geological section. In modeling, a connection is established between the main characteristics of the reservoir: porosity and pore shape, saturation, and mineral composition. In this article, the results of petrophysical interpretation and modeling of the elastic properties are presented on the example of sandy deposits from one of the fields in Western Siberia. At the first stage, the well with a full geophysical complex...

There are rich heavy oil resources in Russia. The paper deals with bituminous sandstones in the southeast of the Republic of Tatarstan (central Russia). The shallow depth and high reservoir thickness of these deposits are very favorable factors for the heavy viscous oil development. Due to this, heavy viscous oil deposits of this territory are of great interest. The conventional approaches for reservoir characterization and development monitoring are complicated for such bituminous deposits. Currently, in the fram...

Nowadays, there is an increasing interest in the tight oil reserves. Such kind of oil have the specific physicochemical properties under conditions of natural occurrence [1]. In this article we consider the solution of the problem of preparing geophysical data for modeling seismic inversion on the example of bitumen deposits. The reservoirs occur at a depth between 150 and 200 m. Thuswise, the accurate processing of geophysical data remains actual. The seismic inversion is usually understood as a group of algorith...
