"Improving the efficiency of operation of complicated oil and gas wells" is relevant in the context of the modern oil and gas industry, where there is a growing need to optimize the processes of production and operation of wells to ensure sustainable and efficient production of hydrocarbons.The research is aimed at identifying innovative approaches and technologies that can improve the efficiency of oil and gas wells, especially those characterized by complicated geological conditions, high fluid viscosity, the presence of aggressive components and other difficulties.The study includes an analysis of existing technologies, methods and tools used in oil and gas production in
order to identify their shortcomings and opportunities for optimization. Particular attention is paid to the development of integrated management and monitoring systems capable of providing well operators with up-to-date information for quick decision-making.
In the course of the research, it is also expected to develop new technological solutions aimed at reducing costs and increasing the efficiency of hydrocarbon production. This may include the creation of new materials for casing pipes, the use of advanced methods of geological structure research, as well as the optimization of production intensification methods.
The results of this study can be used not only in the oil and gas production industry, but also in the development of energy policy aimed at sustainable and efficient use of energy resources.
