The paper describes a computer-aided approach to generation of multiple oil field development scenarios. Evaluation of production performance and economic efficiency of various development scenarios is performed on proxy models of LAZURIT Workstation. Production enhancement operations comprise vertical and horizontal drilling, sidetracking, recompletion of existing wells, and application of dual-completion production systems. The workflow of generation of multiple development scenarios begins from creation of a field-wide model, which integrates LAZURIT proxy models for individual production targets. Then appropriate production enhancement operations are selected. Step-wise introduction of proposed operations is provided for considering geological, operational, and economic constraints. This stage is followed by ranking of the proposed production enhancement operations by eight criteria and year-wise distribution of the proposed production enhancement operations. Key performance indicators are calculated for the entire field by each development scenario. The results obtained for all generated development scenarios are recorded and stored for further analysis and selection of optimal solutions for long-term investment planning. The workflow terminates once development scenarios for all fields have been generated. The described method has been tested using an integrated LAZURIT proxy model for Abdrakhmanovskaya area of the Romashkinskoye field comprising eight production targets of Leninogorskneft Oil-and Gas Production Department. Production enhancement operations under consideration included vertical and sidetrack drilling as well as recompletion. The paper illustrates three scenario generation modes: regular distribution of operations by years, descending ladder method and the best of 500 scenarios according to cumulative production with random distribution of operations. The created tool for computer-aided generation of development scenarios for mature fields significantly improves production of residual oil reserves. Acknowledgement.
