The issues of carrying out lidar measurements of methane concentration in oil production platform operation zones are analyzed. The issue of lidar re-calibration during methane measurements in the areas of oil platform operation zones in wind conditions is considered. It is noted that due to the low efficiency of gas flares, part of the methane does not burn and spreads in the atmosphere by wind. It is noted that in the presence of a headwind towards the meter, an increase in the concentration of not only methane, but also aerosol is observed. In this case, it becomes necessary to re-calibrate lidar for aerosol using the corresponding solar photometer readings.

Based on a review of the literature, it is shown that there are a large number of qualified specialists in the cultivation of microalgae to absorb carbon dioxide in the country, despite the apparent complexity of this method in comparison with the method of injecting it into the layer. Since the absorption by microalgae of the genus chlorella occurs using the energy of sunlight, then with a sufficient amount of it, emissions of additional carbon dioxide are dispensed with. This technology, like no other, depends on climatic conditions: in a climate with an average annual temperature below 0 °C, algae cultivation is impractical, here the only acceptable technology is carbon dioxide liquefaction and its injection into the layer. In a temperate climate, where the largest number of enterprises and cities in Europe and Russia are located, it is necessary to alternate technologies, that is, in summer, cultivate large areas of chlorella according to the technology proposed in the article, and in winter, reduce the area and pump some of carbon dioxide into storage.

The article discusses the processes of soil pollution by oil hydrocarbons in conditions of lens and permafrost. The authors use the methods of mathematical modeling, methods of experimental observations, comparative analysis. The risks of leaks and spills of oil hydrocarbons are indicated as an extremely important issue requiring study using various methods. Brief reviews of the results of studies of soil pollution by oil hydrocarbons are given. A brief analysis of the dynamics of soil pollution by oil hydrocarbons is presented. A hypothesis has been put forward that, when stability is disturbed in lens permafrost, the dynamics of pollutant distribution differs significantly from the dynamics of their distribution under normal conditions. Photographs, drawings, schemes of the distribution of pollutants within the lens and permafrost formations are given. The results of the initial modeling of the spreading of oil hydrocarbons within permafrost lens formations are presented. The process of modeling soil pollution with oil products in conditions of lens permafrost is divided into two stages: the primary modeling of pollution of the permafrost lens itself and the model of the secondary process, when pollutants bypass lens permafrost in the process of diffusion and enter non-frozen soil. The model involves the calculation of areas – pollution halos, as well as the calculation of the surface concentration of pollutants in them. It is concluded that the composition of oil sludge formed with the participation of pollutants is determined by many factors – climatic, physical and chemical, characteristics and composition of the soil. It is concluded that, due to climatic conditions and the state of island (lens) permafrost, the pollution process can differ significantly in dynamics.

To ensure safe and reliable operation of pipeline systems, it is necessary to regularly carry out work on technical diagnostics. Ultrasonic inspection is one of the most common methods for pipeline technical condition determining. It has many advantages over other control methods among which there can be distinguished accessibility, the absence of additional requirements for equipping the object under examination, the absence of an impact on the object of control itself, and safety. But ultrasonic inspection also has disadvantages some of which can be eliminated by using an individual piezo elements of multi-element transducer instead of simple single-element transducers. The method of pipeline wall thickness determining using piezo elements of a multi-element transducer, as well as searching for and identifying the type and size of the defect, is known as ultrasonic tomography. This paper presents the main features of the transducers used in ultrasonic tomography, possibilities of ultrasonic tomography when it is used in field pipeline diagnostics. The advantages of using the method of ultrasonic tomography in comparison with conventional ultrasonic control are considered.

In this paper, a mathematical model of the combustion process of a gas hydrate sample taking into account the non-equilibrium of its dissociation process is presented. The system of basic equations is built on the laws of conservation of mass (for the entire system and each of its components), energy and momentum, and is supplemented by conditions at the moving boundary of the phase transition. On the basis of a numerical solution based on the method of large particles, the fields of system temperature and gas mixture components concentrations are constructed. It has been established that with a decrease in the proportion of water turning into steam, there is an increase in temperature at the combustion front, as well as the speed of combustion front movement.

Pipeline operation in frost areas is essential thing in the present days. Changes of low-temperature profile of frozen soil along the length of a pipeline lead to changing conditions of the pipeline. That’s why it is vital to properly forecast and model thermo-hydraulics regimes and evaluate pipeline conditions to sustain correct positioning of the pipeline and to prevent incidents. That’s why this paper describes a simple forecasting method. It is based on heat balance equation, where coefficient k describing heat transfer from a pipeline to the environment considers that soil gets to technogenic state. Actual efficiency and temperature data from an active non-isothermal pipeline over 2 years period after its commissioning are used to derive actual value of the coefficient k. Pipeline type – underground, insulated, initial petrol temperature is up to 45 °С. Using Shukhov’s formula it is possible to calculate average value of the coefficient k. Based on this coefficient we can then derive forecasted values and get the following data: temperature profile, temperature value at specific points and cross sections of a pipeline, thawing area, critical locations of a pipeline. This method allows to timely evaluate conditions of a pipeline in permanent frost soil. Results can be used to forecast and predict thermo-hydraulics regimes not only for a specific pipeline but also for other Northern ones. It also allows to evaluate conditions of critical parts of a pipeline when taking in account actual size of thawing areas.

Most of Russia's recoverable oil reserves are hard-to-recover reserves. One of the key technologies for the development of these reservoirs is the use of a reservoir pressure maintenance system. The evolution of the development of flood control methods does not stand still. Today, the issue of studying the propagation of self-induced hydraulic fracturing cracks is one of the most important challenges. Over time, as the transition to the development of zones with low permeability values and an increase in down hole pressure in injection wells, the manifestation of the self-induced hydraulic fracturing effect began to be widespread. This was confirmed not only by the dynamics of the water content of products with an increase in the pick-up of neighboring injection wells, but also by hydrodynamic studies of wells, tracer studies, adaptation of the hydrodynamic model taking into account the cracks of the self-induced hydraulic fracturing. Over time, according to the results of studies of geomechanical properties in the deposits of Western Siberia, the direction of the regionally stressed state was established, which coincides with the azimuthal direction of the development of self-induced hydraulic fracturing cracks. Modern development systems take into account the direction of the regional stress state. These systems are mainly located parallel to the cracks of the self-induced hydraulic fracturing to exclude breakthroughs from injection wells to producing wells. Estimation of the parameters of auto-fracturing fractures depending on the injectionmodes is an urgent task that requires the creation of appropriate calculation methods. Control of the waterflood modes for a group of injection wells under conditions of critical bottomhole pressures exceeding the value of the rock fracture pressure is the purpose of this work. A method for estimating the parameters of man-caused fracture from given initial parameters is proposed.

The gas-liquid mixture flow along an oil and gas field pipeline is a complex process, the parameters of which, as a rule, are not determined along its length. Pressure and temperature of water-oil emulsion decrease along the pipeline length, pressure and temperature conditions of separation from oil both light components in the form of associated petroleum gas and heavy components – in the form of asphaltenes, resins, paraffins and mechanical impurities – change. Two techniques for deposit quantitative diagnostics in the pipeline are discussed in the article. Viscosity and velocity of injected reference fluid in the pipeline section complicated by deposits are considered as informative parameters when using pressure sensors and ultrasonic flowmeter. Technologies for the quantitative assessment of deposits in oilfield pipelines based on the control of the movement of a fluid with a reference property different from the property of the pipeline fluid are proposed. According to the first technology, the viscosity of the liquid is changed and the pressure difference at the beginning and at the end of the pipeline with deposits is fixed in time. According to the second technology, the value of the increased velocity of fluid movement in places where the pipeline is narrowed due to the presence of deposits is measured. The theoretical basis of the processes occurring with liquids in pipeline transport is substantiated. With an increase in the viscosity of the reference liquid, the degree of compression of the liquid increases and, as a result, the frequency of vibrations of the liquid molecules increases. With a decrease in the viscosity of the reference liquid, the reverse picture is observed.

The modern structure of industry, outdated technologies form a wide range of environmental problems and sharply worsen the ecological situation. Various methods are used to clean water sources from oil spills: mechanical, thermal, physicochemical, biological. Among the available alternatives, oil sorbents are considered as one the most economical, efficient and environmentally friendly materials because oils can be properly absorbed by oil sorbents without causing secondary water pollution. The purpose of the research is to study the possibility of obtaining an effective magnetically controlled sorption material for cleaning the water surface from oil spills. Research objectives are to analyze the composition of electric arc steel-smelting furnaces (EASSF) dust; conduct research on the hydrophobization EASSF dust with paraffin; determine the optimal proportions of dust and hydrophobizator, which allow the material to maintain buoyancy and magnetic susceptibility; evaluate the interaction of the obtained material with an oil spills on water surface. The dust sample elemental composition was obtained using the ARL9900 Intellipower Workstation. The sorption material was prepared as follows: the EASSF dust was mixed with a sample of paraffin, then it was heated to 105 °C in an oven, mixed, and cooled to a temperature of 20 °C. The true density was determined by the pycnometric method. The method ASTM D2854-70 «Standard Test Method for Apparent Density of Activated Carbons» was used to determine the bulk density. Electric steelmaking waste was used as a magnetically susceptible component. Studies have been carried out on its hydrophobization with paraffin for possible use in water treatment. With the waste : paraffin ratio of 1 : 0.07, a material with high hydrophobicity and buoyancy was obtained. Tests for thickening and extracting a crude oil spill from water surface proved the promise of using the obtained material for cleaning water from oil pollution.

Various methods are used to clean water sources from oil spills: mechanical, thermal, physicochemical, biological. Among the available alternatives, oil sorbents are considered as one the most economical, efficient and environmentally friendly materials because oils can be properly absorbed by oil sorbents without causing secondary water pollution. \u0000The purpose of the research is to study the possibility of obtaining an effective magnetically controlled sorption material for cleaning the water surface from oil spills. \u0000Research objectives are to analyze the composition of electric arc steel-smelting furnaces (EASSF) dust; conduct research on the hydrophobization EASSF dust with paraffin; determine the optimal proportions of dust and hydrophobizator, which allow the material to maintain buoyancy and magnetic susceptibility; evaluate the interaction of the obtained material with an oil spills on water surface. \u0000The dust sample elemental composition was obtained using the ARL9900 Intellipower Workstation. \u0000The sorption material was prepared as follows: the EASSF dust was mixed with a sample of paraffin, then it was heated to 105 °C in an oven, mixed, and cooled to a temperature of 20 °C. \u0000The true density was determined by the pycnometric method.
