“…Research is underway to develop innovative hydrate management techniques, such as the use of hydrate inhibitors and heat exchange systems to maintain optimal conditions. E.H. Al Munif et al (2023) determined that downhole gas-liquid separators are important equipment in the oil and gas industry designed to efficiently separate and treat the gas-liquid mixture produced from wells. In unconventional formations, such as shale or high-viscosity hydrocarbon formations, special solutions are required to ensure optimal separator performance.…”

“…The functional approach provided an understanding of the internal dynamics of the system, which played a key role in optimising and improving each stage of the hydrocarbon production process while reflecting the overall objective of the study to improve the performance of this technology. The formulae used in this study were (1)(2)(3)(4)(5)(6)(7)(8): production methods face the challenges of effective management of multilayer reservoirs, which emphasises the need for a better understanding of the processes involved in lifting production. Developing optimal pressure, flow and control parameters for each reservoir is a key aspect, and successfully addressing this issue can significantly improve field stability and performance in today's energy resource recovery environment.…”

In the context of the active development of gas condensate fields with several reservoirs in the Gogrendag-Ekerem Upland (Korpedje, South Gamyshlja), the study of its technologies is an important area of work. The study aims to optimise the technology of simultaneously separating two gas condensate reservoirs by lifting products with one tubing string to increase hydrocarbon production efficiency. The methods used include the analytical method, functional method, statistical method, synthesis method, and others. In the course of the study, an innovative methodology was developed for the dual completion operation (DCO) of two gas condensate reservoirs, which involves lifting products with a single tubing string. The key element is the refinement of the calculations made. A detailed analysis of the equipment used in the Gogrendag-Ekerem area showed that it can also be effectively used in other regional fields, ensuring the proper functioning of each element above the packer level. At the same time, it is necessary to pay attention to the various individual characteristics of the field to achieve a truly effective configuration of this technology. The new technology incorporates optimised pressure, flow, and control parameters for each reservoir, resulting in increased production efficiency and reduced energy costs. A significant reduction in the negative impact on the environment and an increase in the overall sustainability of the production process have been identified. These features make the proposed technology an important contribution to the development of the oil and gas industry, contributing to more efficient and environmentally sustainable hydrocarbon production and highlighting its potential for application in modern field development. The practical significance of the research lies in the creation of a more efficient and sustainable hydrocarbon production technology, which not only helps to optimise production processes and reduce environmental impact but also provides the industry with a valuable tool to improve overall energy efficiency and sustainability in the face of ever-changing energy requirements and challenges

The relevance of developing analytical methods for studying the stability of root crop cleaners on tractors is determined by the need to improve the efficiency and quality of root crop head cleaning, as this affects the quality of the final product and its marketable properties. The research aims to increase the stability of the cleaner movement by constructing a mathematical model of its oscillatory motion in the longitudinal-vertical plane and its numerical solution to determine the influence of parameters in response to external disturbances. To achieve this goal, a new theory of the movement of a root crop head cleaner in the longitudinal-vertical plane, mounted behind a wheeled tractor, under the influence of the disturbing effect of irregularities in the longitudinal profile of the soil surface on the amplitude and phase frequency characteristics of its angular oscillations was developed. Using numerical calculations carried out on a personal computer, the conditions were found under which the stability of the cleaner's movement in the specified plane will increase when the stiffness coefficient of the pneumatic tyres of the doubler wheels is 315 kN•m -1 .• This result is achieved when the pressure in the pneumatic wheel tyres is 135 kPa. As for the damping characteristics of the doubler wheel tyres, which are determined by the coefficient μ, it was found that when it changes from 350 N•s•m -1 to 1350 N•s•m -1 , there is an invariance of the delay in the reaction of the cleaner to the disturbing effect when its frequencies change from 0 to 24 s -1 . It was also found that the influence of the geometric dimensions of the cleaner is insignificant in the range of frequencies of oscillations of the ordinates of the longitudinal profile of soil surface irregularities from 0 to 24 s -1 . This follows from the nature of changes in the obtained amplitude-frequency and phase-frequency characteristics. The methodology for constructing a mathematical model of the plane-parallel oscillatory motion of the cleaner can be used in similar analytical studies of other agricultural machines mounted on a wheeled aggregating tractor

Artificial lift systems, such as electrical submersible pumps and sucker rod pumps, frequently encounter operational challenges due to high gas–oil ratios, leading to premature tool failure and increased downtime. Effective upstream gas separation is critical to maintain continuous operation. This study aims to predict the efficiency of downhole gas separator using machine learning models trained on data from a centrifugal separator and tested on data from a gravity separator (blind test). A comprehensive experimental setup included a multiphase flow system with horizontal (31 ft. (9.4 m)) and vertical (27 ft. (8.2 m)) sections to facilitate the tests. Seven regression models—multilinear regression, random forest, support vector machine, ridge, lasso, k-nearest neighbor, and XGBoost—were evaluated using performance metrics like RMSE, MAPE, and R-squared. In-depth exploratory data analysis and data preprocessing identified inlet liquid and gas volume flows as key predictors for gas volume flow per minute at the outlet (GVFO). Among the models, random forest was most effective, exhibiting an R-squared of 96% and an RMSE of 112. This model, followed by KNN, showed great promise in accurately predicting gas separation efficiency, aided by rigorous hyperparameter tuning and cross-validation to prevent overfitting. This research offers a robust machine learning workflow for predicting gas separation efficiency across different types of downhole gas separators, providing valuable insights for optimizing the performance of artificial lift systems.
