Implement of dynamic statistical graphics in Web
Only static text and data can be displayed using HTML.As the rapid development of Internet application and the usage of ASP and correlative ASP components has made it possible to display dynamic statistical graphic in browser.ActiveX Server Components ASPChart can be used to create statistical graphics.In this method,client programs use ADO to connect with server database and users can input conditions.The server applications use ASPChart to create statistical graphic and embed the graphic in HTML script,and at last issue it to the clients.The most special characteristic is that the graphics can be stored in disk and used repeatedly.
Time-lapse 3D seismic survey was conducted in the Japan Canada Oil Sands Limited (JACOS) Hangingstone steam-assisted gravity drainage (SAGD) operation area, Alberta, Canada. The objectives of the time-lapse survey were to delineate steam chambers and monitor their growth. A seismic modeling study based on well logs was also carried out to predict the changes in seismic response of the oil sands reservoir due to steam injection. The results of our seismic modeling indicate that the change of the reservoir P-wave velocity due to the steam injection is seismically detectable, and our time-lapse seismic data was consistent with the seismic modeling. The time-lapse seismic monitoring is expected to help better understanding of the heterogeneity of the reservoir sands by integrating the information of the steam chamber geometry and the seismic response analysis.
