Research On Optimizing Valuation And Control Management Of Productivity Construction Projects Of Oilfields

The productivity construction refers to the important activity of converting the oil&gas reserves to oil&gas production capacity via the prophases procedures of research and demonstration, drilling and completing wells, production work, and surface engineering construction. As the typical resource excavating industry, an oilfield development has to face an output digressive situation after its oil&gas output peak period. In order to maintain the sustainable development of the oilfield, it is necessary to conduct the production capacity construction to put the new exploration areas/blocks into production after their production capacity optimization and economic evaluation.On the research of analysis of activities of the productivity construction, the paper researches the project of productivity construction with theory and practice measures. In terms of the characteristics of high risks, high input and high return, concerned widely technical specialties, strong timely, the paper composes a set of practical overall optimization model for the productivity construction projects and establishes the inner system for economic evaluation controlling management based on ERP using project optimizing theory, economic valuation theory and controlling management of projects.The paper optimizes the project designs of the productivity construction, including four subsystems: reservoir engineering, drilling engineering, oil production engineering and surface engineering. With the consideration of all aspects of the oilfields development and establishment of the parameters optimization modules of the four subsystems, the overall optimization module for the productivity construction projects has been conducted by linking the sub-systems through the general target function.The paper appraises economic efficiency of the productivity construction, including financial valuation of project, national economic valuation, uncertainty analysis, and project risk valuation bases on DEA. As for project risk valuation of the productivity construction, it is the first time to apply this measure and model...
