The method of Arps fall curve as an effective method that allows reliable and efficient prediction of well flow, a necessary parameter for optimal and correct choice of well operation is considered in the article. Forecasting the flow rate of wells in fields with high-viscosity oil stocks is one of the most difficult tasks in the development of oil fields. It is proved that the use of the Arps method simplifies this task, as it gives the correct results quickly and easily. The importance of the choice of well operation methods is analyzed. It has been proven that the analysis of reduced production is a means of identifying productivity problems in wells to assess their future productivity and expected service life. The use of the Harmony Enterprise platform is designed to analyze the performance of oil and gas wells and inventory assessment, to create common corporate work processes, use technical knowledge and exchange interpretations, which allows you to identify promising assets, evaluation and development strategy. The results of this work are very important and necessary for further research and analysis of the fall in production and analysis of the well.

The article presents the results of the analysis of the operation of a heat pump in the system of low-temperature rectification of a propane-butane mixture. High-purity propane is obtained from a propane-butane mixture. A "rectification column-heat pump" system is proposed, which transforms the heat removed during the cooling of the component in the upper part of the column into heat absorbed during heating of the bottoms. In accordance with the energy balance of the system, it has been established that part of the heat pump condensation is not used in the distillation column, but is removed to the environment. The heat pump flow diagram contains one evaporator and two condensers. The operation of the heat pump is evaluated from the standpoint of thermodynamics – by the method of energy analysis of the cycle with R134 and R290 working substances, It has been established that the low thermodynamic efficiency of the heat pump is determined by external irreversible losses in the condensers and the evaporator The advantages of R290 as a working substance of the heat pump have been proved and the required theoretical volumetric capacity of the compressor has been determined.

Modern trends in the creation of drinks provide for the use of various infusions, plant extracts, as well as vitamin and mineral complexes, organic acids and polysaccharides as part of their bases, which allows to ensure the normalization of physiological and metabolic processes in the human body and prevent a number of diseases and syndromes that lead to a decrease in working capacity. The main problems in the creation of various drinking forms are associated with the purification and preparation of water, the dissolution of components and their possible interaction with each other in the packaging unit during storage. Considering the above, it is relevant to create dry concentrates of health-improving drinks with long shelf life. The developed approach and technology is a promising form of drinks to improve the living standards of the population of Ukraine and other countries. The developed products will improve immunity, prevent a number of nutritional diseases, improve dietary intake during diet therapy and help restore micronutrient balance in the human body. It has been established that the physiological value of dry drinks according to the described production method is preserved in finished product forms (sticks with a metallized backing, sachets, sachets with a “zip-fastener” and a metallized inlay, plastic cans with a screw cap and with polymer backing as a control against preliminary opening) the entire recommended shelf life is from 12 to 24 months. The mixture is a convenient form for transportation and preparation. When diluted in liquid media (purified drinking water, mineral water, milk, fermented milk drinks, drinks based on plants, cereals, legumes, tea, coffee, cocoa), the specified functional properties are preserved and improved due to the activation of biologically active substances contained in the mixture and dilution media. The novelty of individual technological solutions and the indicated physiological and functional properties lies in the use of extracts of plants, fruits, berries, vegetables, as well as additionally introduced vitamins, mineral salts, amino acids, hydrolysates and isolates of plant proteins, natural bioenhancers and bioactiators with unique anti -age "effects.

The object of the thesis is the use of steganographic methods for organizing a covert communication channel in a public channel, providing resistance to lossy compression. The aim of the thesis is to develop an algorithm for embedding data into bitmap images that is resistant to JPEG compression and attacks on the container. In this thesis, the features of the JPEG algorithm are investigated, steganographic methods of information protection are analyzed, and a steganographic algorithm is designed that is resistant to JPEG compression and attacks on the container. Additional security is provided by the polyalphabetic substitution cipher and user secret key used to encrypt the original message. The algorithm was developed using the Python 3 programming language, the NumPy, SciPy, MatPlotLib libraries and the Jupyter Lab package. The task was completed using standard mathematical and statistical methods and tools of the high-level programming language Python 3.

The object of the work is the technology of manufacturing radio-absorbing ceramics on the basis of facing tiles with the addition of silicon carbide. The method of hydrostatic weighing in water was used to determine the physical properties. X-ray phase analysis and spectral characteristics - transmission and reflection coefficients, in the frequency range 25.8 – 37.5 GHz were also determined. Tiles consist of two layers. First, separately obtain a press powder for the I and II layer of raw materials in a given amount, which were weighed, moistened, ground in a ball mill; the slip was dried in an oven, then ground and passed through a suitable sieve. The moistened press powder for the first layer was weighed and poured into a mold for pressing, after which the moistened press powder for the second layer was weighed and poured into the mold for pressing. The resulting raw material was dried. The semi-finished product was covered with watering and placed in an oven. The finished semi-finished product was fired in a silite furnace. The two-layer tile with an irrigated covering made on the developed technology was characterized by the following characteristics: water absorption – 9,8 %, imaginary density – 1,90 g/cm3. The developed ceramics, according to the classification, can be referred to the class of radio-absorbing ceramics.

The materials of the article consider the effectiveness of additives for stabilization and dilution of clay-free slippers. For theproduction of radio-transparent ceramic materials of Celsius-Willemite composition, the most efficient and energy-saving methodof production is the method of slip casting. According to the charge composition, this technology is complicated by the lack of claycomponents, which shows the need to use impurities to improve the rheology of such a slip. The main characteristics of aqueousceramic slippers are density, humidity, fluidity, viscosity, density factor, rate of mass accumulation. The slip must meet thefollowing requirements: be free from foam and gas inclusions, have satisfactory fluidity under low viscosity; be aggregativelystable (characterized by the absence of aggregation, coagulation and sedimentation of solid phase particles); have a high filteringcapacity to ensure fast and defect-free weight gain; to be chemically inert, to provide sufficient strength and low shrinkage of semifinished products, as well as the possibility of their easy release from the mold.
