“…Dynamics of temperature changes in the interval from 0 to 2°С above zero at the surface of the heater case proves reliability of the designed device and applicability of the earth warmth for well head heating [6,7]. Convectional heat interchangers for transmitting earth warmth to injection tree KT-SH-114 and КТ-S-48 were designed basing on these tests [8].…”

Different systems of stratal flooding by mineral or fresh water into oil bearing formation are used today to enhance reservoir recovery. At low temperatures, 25 degrees below zero and lower, there is a great possibility of freezing of the well head equipment due to cyclic flooding or separate horizontal flooding, lessening injection capacity of the well, emergency stops in flooding, due to water pipe breakage or power cutting off. Besides the wells, crossover bends from water injection wells to the pipe header, and stagnation zones of the embedded in grooves pipes can freeze. According to expert estimation of PJSC "Tatneft" specialists, the amount of frozen injection stations is more than 500 wells per year. Due to the urgency of the issue technological measures have been developed to prevent oil-field equipment freezing.

“…It is well known that the fields of application of various methods for enhancing oil recovery are determined by the peculiarities of the geological structure of impact objects [1][2][3][4][5][6]. The presence of a wide range of these methods is explained by the diversity of oil fields, which requires a justification of their use.…”

Currently, the use of gas methods to increase oil recovery is underexplored. However, the experience of applying these methods, both in Russia and abroad, indicates their high technological and economic efficiency. The article takes the first step towards substantiating the use of gas methods in the conditions of operational facilities in Bashkortostan. The goal of the research was to carry out a forecast of the results of gas exposure on hard-to-recover and residual oil reserves in Bashkortostan fields. The objectives of the research were the creation and adaptation of mathematical models of oil displacement for the conditions of productive objects and the fulfillment of the forecast for an increase in the production of residual oil reserves in the fields. The studies were carried out using models of filtering processes of multicomponent mixtures, a three-dimensional formulation of the problem and complex boundary conditions of polygon objects. The completeness of the generation of residual reserves was calculated. As a result of the research, a mathematical model of gas exposure to hard-torecover and residual oil reserves was adapted to the geological and field conditions of the Volga-Urals, which allowed for a reduction in the volume of calculations. The article presents the results of mathematical modeling of the process of displacing oil from the porous medium of the reservoir rocks of the fields of the Republic of Bashkortostan through the use of gas exposure.

The method of pulsed non-stationary flooding is a continuous regulatory process. Its optimal variant is determined by the stage of development of reserves. It is selected after a thorough analysis of the development, when the current oil reserves are determined differentially by zones and sections of the reservoir and the forecast of the dynamics of their extraction under the existing development system is given. Then the comparison of the development indicators of pulsed nonstationary flooding options with the ones for the existing (nonstationary) acting system is conducted, and the optimal variant is chosen.
