“…As can be observed from the above equations, the movement of oil in the structural regime is not amenable to analytical solution and requires a search for empirical formulas for hydraulic calculations. To determine the Ilyushin criterion, it is necessary to study the rheological characteristics of oil, which will determine the law of change in rheological characteristics, depending on the temperature and mode of motion [27][28][29][30][31].…”

This article analyzes the dependence of the choice of the method of transportation of high-viscosity oil on the rheological characteristics of the oil in question. An analysis of existing rheological models of high-viscosity oil was carried out, and it was found that a number of models have certain features (model coefficients, their purpose, quantity) that affect the choice of a rheological model of oil. The dependences for determining the coefficient of dynamic viscosity when pumping high-viscosity oil with the addition of pour-point depressants were studied, and the dependence of the hydraulic resistance coefficient when depressants are added to the oil was obtained. A method for choosing a rational oil heating temperature and diluent concentration to achieve the maximum pipeline performance is substantiated.

“…The quality of motor fuels determines the operational and environmental characteristics of vehicles (4)(5)(6). The group chemical composition of motor fuels is the determining factor in the formation of their quality indicators and operational properties (7,8). To search the individual hydrocarbon composition of light motor fuels (petrol, paraffin, diesel fuel), the method of gas chromatography-mass spectrometry (GC-MS) is quite effective.…”

This article presents the results of engine and laboratory tests with fuel before and after treatment with a heavy particle generator. The results of the research have shown that in the course of conducted research the impact of heavy particle generator on fuel during engine tests leads to an increase in its detonation resistance and a reduction in fuel consumption (up to 15%), as well as significantly improves the environmental performance of the engine. The reduction in concentration of carbon monoxide (CO) from 0.09% to 0.03%, carbon dioxide -by 6% and nitrogen oxides -by 7%. The results of research of hydrocarbon composition of fuels by GC-MS method have shown that the impact of heavy particles generator have a favorable effect on the octane number of gasoline, as well as low-temperature properties of diesel fuel. The change of engine operation parameters after the impact of heavy particles generator is established. The change can occur as a result of complex influence on fuel and engine systems, and as a result of influence on a single factor, which is the root cause of the subsequent change of parameters.

“…Drilling wells is necessary to extract oil and gas from productive formations located deep underground (1)(2)(3). Drilling fluids play an essential role in the drilling process as they perform many functions, such as removing drill cuttings and controlling well pressure (4,5). Several chemicals are often used as additivies to the drilling mud.…”

Drilling muds play the essential role the drilling process as they perform many functions, such as the removing of drill cuttings and controlling well pressure. Water-based drilling muds, through the use of more environmentally friendly additives, can meet increased environmental requirements. Many researchers have studied the effects of different natural materials on drilling mud to find environmentally friendly and effective drilling mud materials. The popularity of using waste materials is mainly due to their cost and favourable environmental impact. Performed literature review showed that the rheological and filtration characteristics of water-based drilling muds are enhanced with the addition of leaves of various plants and trees. This article presents investigations of clay-free drilling mud with the addition of birch and aspen leaf powder. This is relevant in the autumn period, since fallen leaves are solid municipal waste and should be disposed of by removal to landfills. The obtained data indicate the possibility of using leaf powder in the drilling mud composition. Addition of leaf powder to the base mud increases the gel strength and plastic viscosity of the mud. In an extent reduces the yield point and filtration index. Rheological parameters increase by 10-30% and filtration index decreases up to 15-17%.
