Thickness analysis shows that the Lower Eocene sandy horizons are distributed locally in Tovuz-Gazagh, GiragKasaman and Mammadtapa areas, and have lens-shaped morphology. This creates conditions favorable for lithological traps formation. In some areas, tuff reservoirs of the Middle Eocene age are onlapping on the local uplifts. Possability of lithological traps formation in suchareas is high. On the west part of northern zone of Kur and Gabyrry interfluve the well-sorted tuff-terrigenous rocks are predominating. It is supposed that sediments along the north - northeast border of the area will be similar to those in near Tbilisi area, and consist of fine-grained tuff-terrigenous rocks with interlayers of shale and marl. From the similar reservoirs of the Middle Eocene the oil is produced in Tarsdallar and Gurzundagh areas of Kur and Gabyrry oil-gas region.

For different low-productive deposits groups in the West Siberian oil and gas province Terrigenous reservoirs that are coming out of exploration, a methodical approach to individual problems solving in the drilling strategy search and justification, flooding systems, wells spacing system choosing, the need to use non-traditional approaches to flooding and production organization (the use of horizontal, multibranch, multilateral wells, etc.), optimal bottomhole pressures and operating modes for producing and injection wells with the aim of low profitability deposits’ active involvement in the development is proposed. The approach is based on the use of information on deposits that can in sufficient volume and with sufficient accuracy be obtained at the stage of geological exploration, when the use of hydrodynamic models is a matter of some difficulty. The necessity of a differentiated approach to solving problems using the analogy method is shown.
Keywords: withdrawal of deposits from exploration; low-productive deposits; analogy method; contour waterflooding.

In the article describes the studies carried out on the direct forecasting of hydrocarbon deposits by RWM of seismic exploration, high-precision gravity and magnetic survey in the Uchtol-Kutarma area of the southern side of the Fergana depression. Within the area studied, a number of anomalies associated with the presence of oil and gas deposits were identified, exploration drilling was recommended. According to the results of exploratory drilling of well No.1 in Kutarma area, the identified anomalies were partially confirmed.

The article presents the results of the effect of the sediment-forming composition on the heterogeneous reservoirs with high water-cut, which are at the last stage of development and contain large amounts of residual oil in the pores. The applied new composition, when interacting with stratal waters, as a result of coagulation and flocculation phenomena, forms stable sediments in the formation. These sediments, even at high pressures, retain their stability, penetrating into the pores of flooded formations (ie, they are not washed out of the pores). As a result, after the injection of the working agent, the coverage of low-permeable zones containing residual oil improves. And this allows you to increase the rate of displacement of oil using working agent.
Keywords: water shutoff; heterogeneous reservoir; new sediment-forming composition; porous media; permeability; high-permeable zone; low-permeable zone; residual oil; rim; alkaline water.
The highly-mineralized formation waters of oil fields impede the development of microbiological processes. In order to increase the efficiency of microbiological methods of influencing the formation and use them in formations having conditions, which are unfavourable for microorganism activities, a new microbiological method of oil recovery increase was developed in which a rim of low-saline flush fluid was used prior to the injection of organic substrate. As an organic substrate, a composition of two types of milk whey was used. In this case, an oil recovery factor of 74% was obtained. The developed method provides a means for effectively dealing with issues of non-waste technologies creation, and for the improvement of the ecological situation at developed deposits.
Keywords: biotechnology; oil recovery; highly-mineralized water; microorganisms; model; recovery factor.

An integral model is constructed and the related gas motion equations in the reservoir system are jointly solved taking into account the reservoir deformability. Based on this, the wellhead process parameters determine the pressure at the bottomhole and in the reservoir of wells and the flow of gas into the well per unit time.
Keywords: filtration; Laplace transformations; gas motion; gas flow; differential equation; deformable collector; elastic waves.

The paper presents the study results of the acoustic effect the oil well bottomhole zone by ultrasonic waves. The formulas allowing to estimate power density of an acoustic wave and its attenuation coefficient are received. Experimentally by three independent neutron logging methods, the acoustic effect effectiveness was shown to increase the bottomhole zone permeability. The experiments were conducted on oil facilities in Tatarstan and Western Siberia. The estimated data on the threshold intensity of the ultrasonic emitter in the well and depth of the effective acoustic impact on the oil reservoir are given.
Keywords: oil; well; penetration; flow rate; ultrasound; acoustic influence; neutron control.

Pipelines impose a regular constraint on the outgoing transport and downstream market of shale gas in its exploration and exploitation processes, thereby affecting its commercialization. Based on the current status of China’s oil and gas pipeline networks, this study presents an influencing factor index system based on the requirements for optimal outgoing pipeline routing. Specifically, this index system covers five aspects of influencing factors: engineering, economics, safety, environmental, and potential utility. After taking the related constraints into account, this study presents an optimal multi-attribute decision-making (MADM) method for outgoing pipeline routing program preference of shale gas based on intuitionistic fuzzy sets. Using the example of the alternative routing solutions for outgoing pipelines in a block, a decision-making process based on the MADM method is introduced.
Keywords: outgoing pipeline of shale gas; multi-attribute decision-making method; pipeline route layout; intuitionistic fuzzy set.

The use of modern information technologies, including the Internet of things, contributes to the effectiveness of industrial production in the oil and gas sector. Solutions in this area are constantly developing and provide great advantages in terms of increasing the speed of exploration and detection of oil and gas, increasing oil production and reducing risks to health, human security and environment. The
article is dedicated to the study of these issues and the development of a conceptual model of the system based on the industrial internet of things.
