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 work is devoted to the review of methods for mapping the area of seismic exploration using UAVs. When planning seismic surveys, obtaining a digital terrain model (DTM) and a digital surface model (DSM) for the polygon is a mandatory procedure. The resulting models can be a source of critical information. Obtaining data on the relief and terrain surface with aerial vehicle, today is carried out using aerial photography and laser scanning. Obtaining data on the relief and terrain surface with aerial vehicles, t...

The paper describes the results of 1D geomechanical modeling in the territory of Akan oilfield in the Republic of Tatarstan, the Russian Federation. The data of sonic and density logging, which are the basis in the construction of the geomechanical model, were analyzed. The velocity and density properties of carbonate rocks in the study area are stable both along the section and the strike. Sonic waveform logging data were processed for a number of reference wells. The results of processing were taken as the basis...

Determination of the velocities anisotropy and direction of fast and slow shear waves propagation in the reservoirs containing hydrocarbon deposits is important for the choice of a field development model. The paper describes computing technique the magnitude of the shear waves anisotropy and the assessment of the preferred propagation directions for fast and slow shear waves in the Akan oil field, Republic of Tatarstan, the Russian Federation. In the course of the work, the cross-dipole acoustic logging data were...

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...
