Advancements in currently available modeling and digitization technologies offer new opportunities for development of investment programs and revitalization of oil production from mature oil fields. Integration and combination of reservoir engineering and operation solutions by multidisciplinary expert teams, modeling and digital technology specialists substantially improve the efficiency of investment projects while reducing geological, technological and subjective judgment risks. The resultant suite of solutions for producing fields is synergistic (interconnected) on the one hand, and a flexible tool for field development planning and management, on the other hand. Application of end-to-end processes with participation of specialists involved in well logging, seismic survey, geological exploration, reservoir engineering, modeling and digital operations allows for more thorough analysis of input data to identify bypassed oil reserves and reduces the risk of overestimation of depleted reservoir zones, while interrelated project solutions enable synergetic effect from various operations. Integration of digital tools into production processes, as well as the development of big data and predictive analytics tools for designing of investment projects allow upscaling of originally complex research methods for selection and evaluation of activities at the scale of company's group of assets and shifting of human resource functions to intelligent operations. Favorable results from investments, confirmed by the successful production enhancement operations in mature fields carried out by the authors, on the one hand, reveal the potential of Russian oil industry trends, and on the other hand, highlight the necessity to reconsider the required expertise of managing staff and project team participants to improve their understanding of related industry applications and up-to-date digital tools.
