Geosteering system is an advanced multi-disciplin e applied science drilling and Geology research technology which use the real-time formation information returned by the survey tool that was installed near by the drilling bit underground to adjust drilling parameters in order to keep drilling trajectory in the oilgas production layer as long as possible.Geosteering real-time system can transfer real-time data from drilling site to remote research center and help engineer’ s decision analysis.Oracle instead trigger can solve Application problems multiply data source and heterogeneous database during the data receive and date application processes.
