The paper discusses the ways of improving well intervention solutions for oil reservoirs by implementing advanced energy-saturated materials. The paper reviews issues encountered in a conventional tubing-based technique including long execution periods, shortage of well servicing crews, complexity of equipment transportation and maintenance, inadequate reliability and quality control of the operations performed. The authors offer an innovative technique involving application of a logging cable and the next-generation energy-saturated materials. The paper details the design and operating concept of the new technology, including application of thermal gas-generators based on energy-saturated materials which produce the required pressure for setting packers in the wellbores. Laboratory and field test data are presented indicating feasibility and efficiency of the proposed technique. Particular attention is given to the benefits of the proposed technique compared to a conventional tubing-based method, including a shorter execution period, reduced financial expenses, improved reliability and safety of operations. The authors present technical characteristics of the equipment in use and the materials for experimental studies, which confirm viability and practicability of the proposed technology. Moreover, the authors recognize the importance of further development of this technology and expansion of its applicability, emphasizing the necessity for further research studies and engineering-and-process solutions to exploit the full potential of the innovative technology. Thus, this paper contributes substantially to the development of efficient and cost-effective oil production technologies aimed at improvement of performance and environmental sustainability of oil and gas prospecting and development processes.
