Optimization methods for well designs, drilling and well completion technologies

Background. The task of increasing the efficiency of well construction, reducing the labor- and financial costs involved, and achieving the maximum operational characteristics of oil and gas wells requires the application of the most recent technologies and technological solutions for well drilling and well completion.Aim. Review and analysis of the implementation and development of promising technologies for well drilling and well completion in the Russian Federation to identify those capable of optimizing well designs, improving the efficiency of technological processes for drilling and completion of exploration and production wells.Materials and methods. An analysis of accumulated experience, generalization of the results of implementation of modern solutions and technologies for drilling and completion of wells by oil- and gas-producing enterprises of the Russian Federation.Results. The relevant tasks and directions for improving drilling and well completion technologies and using state-of-the-art equipment are outlined. These solutions can contribute to increasing the efficiency of well construction, reducing the drilling duration of oil and gas wells, and ensuring technological sovereignty.Conclusion. The considered directions and technologies, as well as their composite tasks and methodological, engineering, and software implementation aspects, can become a subject for research, project, and engineering works, as well as for final qualifying works of students and dissertations.
