The article is devoted to the optimization of sea surface pollution control using the laser-fluorescence method. Two optimization variational problems for remote detection and assessment of sea surface pollution by oil and oil products have been compiled and solved using the fluorescence method. The solution of the first problem on the optimal choice of the wavelength of the emission signal was carried out according to the criterion of achieving maximum information content. The solution of this problem made it possible to determine the wavelength in multipoint laser sounding of sea waters. The solution of the second optimization problem made it possible to determine the optimal form of the dependence of the optical thickness of atmospheric aerosol in the used wavelength range of optical fluorescent emission.

The main problem in the development of the Priobskoye field is the search and implementation of technological solutions for the most efficient development of layers of ultra-low permeable reservoirs. A factor complicating the hydrocarbon production for such facilities is the low impact of flooding. These restrictions lead to high rates of decline in oil production, therefore, the most urgent issue is the search for an up-to-date technological solution aimed at improving the efficiency of field development. This article is devoted to improving the efficiency of the development system in areas with low filtration and capacitance properties. It presents the results of research on the study of the construction of horizontal wells longitudinally and transversely to regional stress, followed by multi-stage hydraulic fracturing in the conditions of one of the largest fields in Western Siberia. The results of the research made it possible to determine an effective strategy for designing development systems in future areas. The relevance of this work: the demand for the extraction of hard-to-recover reserves from reservoirs characterized by low permeability.

In the global pipeline transport, including main pipelines (MР) with a long service life (40 years or more), the reliability of operation is ensured by compliance with regulatory requirements. Calculations of the stress-strain state of gas pipelines, in particular, longitudinal stresses, are carried out in accordance with Standart SP 36.13330.2012 «Main pipelines», which does not take into account the life of the facilities. The analysis of SP 36.13330.2012 «Main pipelines» for the effect of the temperature factor on the magnitude of the longitudinal stresses of the gas pipeline section showed that the calculation of longitudinal stresses from the temperature difference ∆Т provides for taking into account four values: Тс – maximum and minimum temperatures during construction; Tр – the highest and lowest temperatures during operation. When considering the stages of construction of gas pipelines, it was established that during this period the pipeline experiences the action of four temperature regimes, and when put into operation, the fifth complex one: from the temperature and pressure of the gas, at which the consolidation of the main pipeline with the surrounding soil occurs predominantly in during which the linear-altitude position of the MР section with a minimum of stresses is predominantly formed. It has been proved that, in relation to the calculations of longitudinal stresses of gas pipelines with a long service life, it is necessary and sufficient to limit the calculated temperature difference by Tр. SP 36.13330.2012 is intended for calculations during the construction of new pipelines, and its use for long-term operated gas pipelines, taking into account the standard value of ∆Т, mainly leads to rejection, and, therefore, to repair. We believe that for the operation of MР with a long service life, for the calculation of thermal stresses, it is necessary to develop a standard that allows the calculation of the temperature difference ∆Т by the value of the operating temperature Tр.

Concrete production is one of the most power consuming processes in construction, which emits large amounts of CO2. The use of utilized carbon dioxide in concrete production can reduce the carbon trace of concrete production and therefore reduce its negative impact on the environment. The relevance of CO2 utilization in concrete production is due to several factors: 1. Environmental issues: Concrete production is one of the largest sources of carbon emissions. Therefore, the search for ways to reduce carbon emissions, including by CO2utilization, is relevant and obligatory. 2. Consumer Interest: An increasing number of consumers are oriented on environmentally friendly products and services, so the use of utilized CO2 in concrete production can increase the product attractiveness. 3. Starting the transition to a low carbon emitted economy: Due to growing global trendto carbon emission reduction, many countries and organizations are transiting to a low carbon emitted economy. New technologies such as the use of utilized CO2 in concrete production can contribute to this transition. The aim of research: the development of a pressurized concrete mixer. Object of research: concrete mixture with CO2. The article describes the design, principle of operation and schemes of a concrete mixer operating under pressure. This device was designed at the Almetyevsk State Institute in the laboratory of the Center for Scientific and Technical Research to conduct an experiment on concrete carbonization.

Oil in the northern regions has a positive solidification temperature, so it needs to be heated to ensure pumping. Oil must have a high positive temperature along the entire pipeline length, which leads to a number of issues related to maintaining a positive temperature of oil in the pipeline along its entire length. Taking into account all the geological and climatic features of the Far North, for reliable and safe operation of the oil pipeline it is necessary to ensure the required temperature of the transported product, preventing pumping stops and preventing energy consumption overruns. During the operation of pipelines with thermal insulation, moisture is formed in the thermal insulation layer for a number of reasons. Water gets under thermal insulation in two ways: as a result of condensation or comes from the outside. In addition, the thermal insulation itself can absorb and retain water, which subsequently turns out to be under insulation. Condensation may occur when the operating temperature of the surface changes. Prolonged exposure to leaked or condensed moisture on the outer wall of the pipeline is the cause of corrosion under thermal insulation. The development of the process is quite complex, and has a number of features that distinguish it from conventional corrosion. The nature, speed and degree of damage to the surface are strongly influenced not only by the characteristics of the aquatic environment (hydrogen index, composition and concentration of dissolved electrolytes, etc.), but also by the ability of the insulating layer to release corrosive agents – chlorides and sulfates under the influence of water. Chlorides and sulfates are water-soluble substances, their aqueous solutions have high electrical conductivity, which increases the corrosion intensity. Also the features of moisture accumulation of thermal insulation, which directly depends on the microstructure of the material are important. During operation, the outer surface of the insulated pipelines is inaccessible for visual inspection without opening the insulation, and the beginning of corrosion in this case is difficult to determine, as a result, severe corrosion may occur with subsequent loss of integrity of the pipeline wall. The aggressiveness of the environment under thermal insulation is due to several factors: high temperature, the presence of moisture and chemicals. The problem of metal corrosion is considered to be one of the most significant in safe operation of industrial facilities, as well as reducing the damage to the economics and the environment. Corrosion protection under thermal insulation is a serious problem requiring special attention.

The assets of Rosneft Oil Company PJSC include oil and gas reservoir that have not been put into development, in addition, the resource base is being replenished through geological exploration. The use of new technologies in exploration and production, the introduction of new software modules for calculations, tax regimes for oil production create prospects for increasing production from oil and gas reservoir that have not been put into development in the whole of the Russian Federation. At the stage of decision-making on putting new assets into development, it is required to be able to conduct an express assessment of technological indicators. This paper presents the results of the formation of analytical approaches for carrying out express calculations of the development indicators of oil and gas, gas-oil and oil-gas condensate reservoir that have not been put into development. The calculations are based on the use of a set of pre-calculated displacement characteristics and the material balance equation of hydrocarbon reservoir. All developed algorithms are implemented in a new software module, which is an integral part of the RN-KIN corporate information system, the main tool for a development engineer at Rosneft Oil Company PJSC. This paper reflects the mathematical description of the algorithm for the express calculation of development indicators, the main tasks that were solved in the course of the work, and the results obtained.

Gas hydrates are the object of continuous research in the oil and gas industry. Gas hydrates can form in gas production systems: in the bottomhole zone, in the wellbores, in plumes and infield reservoirs, in gas treatment systems, as well as in main gas transport systems, causing serious problems associated with the disruption of these processes. However, recently, the gas industry has found new uses for hydrates (for example, energy recovery, separation, storage, and transportation of gas) prompting scientists to conduct new and more detailed studies of the hydrate formation process. Understanding the conditions and mechanisms of hydrate formation makes an engineer able to control this process. Therefore, in practice, simplified models are often required to predict hydrate formation. This paper presents various correlations that are widely used in the oil and gas industry to determine the temperature of hydrate formation. The accuracy of the presented models is compared. The influence of the features of the gas composition on the conditions for the hydrates formation is studied. It is shown that for the considered gases, the most accurate results can be obtained using the G.V. Ponomarev correlation. When the relative density of gases is greater than 0.6, it is possible to use the Towler and Bahadori correlations. Correlations proposed by Hammerschmidt, Mottie and Berge show the worst results. Since the temperature of hydrate formation in the considered correlations does not depend on the gas composition, but only on the relative density, the influence of the content of non-hydrocarbon components on the temperature of hydrate formation was studied in this work. It was found that the content of hydrogen sulfide has the greatest influence. Moreover, at high contents of hydrogen sulfide in the gas composition, the temperature of hydrate formation shifts towards higher values. The content of nitrogen and carbon dioxide to a lesser extent affect the value of the temperature of hydrate formation.

One of the most common types of ecotoxicants are petroleum products - an unidentified group of petroleum hydrocarbons and products of its processing. In this regard, the development of technology for obtaining new highly efficient and inexpensive sorbents for wastewater treatment from petroleum products (including those based on industrial waste) is an urgent problem. In this paper, a method of wastewater treatment from petroleum products using composite sorbents based on waste-tailings of Uchalinsky (SU), Buribaevsky (SB), Sibaysky (SS) mining and processing (GOK), and clay of the Talalaevsky deposit (G) and sodium humates (GN) obtained from the waste of the Tyulgan brown coal. The efficiency plants of purification was investigated using these sorbents of model wastewater contaminated with oil from the Vozeyskoye field of Usinsk Neftegaz LLC and real wastewater from the Ufa refinery of ANC Bashneft. It is shown that the efficiency of purification and the rate of adsorption of model wastewater containing petroleum products (8-50 mg/dm3) increases in a number of sorbents BAU - A < CC + G < SB ++ G < SU + G SU + G + GN (where BAU - A sorbent of comparison, activated carbon) and are maximal for GOK covered with GN. For real wastewater containing petroleum products of the Ufa refinery (3-625 mg/dm3), the adsorption activity increases in the series CC + G < SB ++ G < SU + G. Thus, the most effective sorbents for real and model wastewater containing oil and petroleum products are sorbents based on Uchalinsky GOK waste in a composition with clay (degree of purification 96.1 %), as well as SU modified GN (98.2 %).
最常见的生态毒物之一是石油产品——一组未识别的石油碳氢化合物及其加工产品。在这方面，开发从石油产品(包括以工业废料为基础的产品)中获得新型高效廉价的废水处理吸附剂的技术是一个迫切的问题。本文研究了以Uchalinsky (SU)、Buribaevsky (SB)、Sibaysky (SS)开采加工(GOK)的废尾矿、Talalaevsky矿床(G)的粘土和Tyulgan褐煤废料中腐植酸钠(GN)为基础的复合吸附剂处理石油产品废水的方法。利用这些吸附剂对Usinsk Neftegaz LLC的Vozeyskoye油田的模拟废水和ANC Bashneft的Ufa炼油厂的实际废水进行了高效净化装置的研究。结果表明，BAU - a < CC + G < SB ++ G < SU + G SU + G + GN(其中BAU - a为对照吸附剂，活性炭)对含石油产品模型废水(8 ~ 50 mg/dm3)的净化效率和吸附速率均有提高，且对GN覆盖的GOK的净化效率和吸附速率最大。对于乌法炼油厂含石油产品的真实废水(3 ~ 625 mg/dm3)，吸附活性在CC + G < SB ++ G < SU + G系列中增加，因此，对含石油和石油产品的真实废水和模型废水最有效的吸附剂是含粘土的乌chalinsky GOK废物(净化度为96.1%)和SU改性GN(净化度为98.2%)。

In this regard, the development of technology for obtaining new highly efficient and inexpensive sorbents for wastewater treatment from petroleum products (including those based on industrial waste) is an urgent problem. In this paper, a method of wastewater treatment from petroleum products using composite sorbents based on waste-tailings of Uchalinsky (SU), Buribaevsky (SB), Sibaysky (SS) mining and processing (GOK), and clay of the Talalaevsky deposit (G) and sodium humates (GN) obtained from the waste of the Tyulgan brown coal. The efficiency plants of purification was investigated using these sorbents of model wastewater contaminated with oil from the Vozeyskoye field of Usinsk Neftegaz LLC and real wastewater from the Ufa refinery of ANC Bashneft. It is shown that the efficiency of purification and the rate of adsorption of model wastewater containing petroleum products (8-50 mg/dm3) increases in a number of sorbents BAU - A < CC + G < SB ++ G < SU + G SU + G + GN (where BAU - A sorbent of comparison, activated carbon) and are maximal for GOK covered with GN. For real wastewater containing petroleum products of the Ufa refinery (3-625 mg/dm3), the adsorption activity increases in the series CC + G < SB ++ G < SU + G.

Monitoring the condition of pipelines and site facilities of the oil and gas trunk transportation system, as well as other facilities of the oil and gas complex, allows you to collect the necessary information quickly, getting into hard-to-reach places where land transport or a person cannot get to, and reduce the response time to emergency situations and eliminate their consequences. The paper considers the existing designs of unmanned aerial vehicles used in systems for remote monitoring of technological facilities, analyzes their advantages and disadvantages while inspecting the linear part of the trunk pipeline. Two variants for automated platforms placing along the route for taking off and recharging unmanned aerial vehicles are proposed. The first variant allows more thorough inspection while flying around, the second one allows using fewer platforms and longer inspection area.

The article deals with the formation of flooded development objects at oil fields in the West Siberian sedimentary-rock megabasin. They are a direct result of the vigorous activity of geological processes in the bowels of the earth. A detailed analysis of the primary geological and field materials carried out by the authors of the article clearly showed that they began to form as a result of forced exploitation of deposits, when the current water cut of production wells sharply increases. As a result of the studies performed, the causes of watering of productive formations were identified and practical recommendations were proposed for conducting technological studies to reduce the watering of the well.
