Design and Applications of Digital Oilfield

In this paper, the applications of Digital Earth in oil and gas exploration and production, oilfield management and decision-making, the Digital Oilfield are researched. The fundamental technologies of Digital Earth in development and application systems can be summarized as 4I, they are Immersive Visualization, Internet Enabled, Integrated Data warehousing, and Intelligent Modeling. Digital Earth is not just Web-GIS, VR-GIS, or online 3S system (GIS, GPS, RS). In order to extend Digital Earth to Digital Oilfield, the SIM (Subsurface Imaging and Modeling) is considered, then the Digital Earth will be used for scientific and industrial exploring from Earth surface to subsurface, even to Earth mantle and core, such as digital oilfield, digital lithosphere, and digital biosphere, for industrial and social information management, and for innovative ways of education and entertainment. The main improvement of Digital Oilfield in contrast to the original great computer center is that many oilfields have focused on oil and gas integrated forecasting, reservoir dynamic modeling,oilfield management and decision making, and exploration data warehousing. The immersive environment can provide stereoscopic 3D images of the complex data, which makes users easier to understand, easy to do collaborative teamwork, easy to interpret, easy to make decision, easy to manage, easy to do perceptual computing, and so on. A typical Digital Oilfield system can be divided into the following aspects: super workstation or computer cluster for computing and graphics generating, virtual reality and 3D projection systems for immersive visualization, wide band network, storage area network as Data warehouse, virtual reality system software, oilfield data processing software, develop software, data sharing software for multi-source and hetero-database seamless integration and so on. Suggestions on how to realize a Digital Oilfield system and its configuration are put forward. The key related technologies and applications of digital oilfield are analyzed in detail. Finally, we concluded that the only way to solve the problems that oil and gas department confronted with is to adopt new ideas, new theories and new technologies.
