Est POSC-Caesar

Significance:  Technical innovations  Keep Kansas competitive  Web-based business transactions  Incubate entrepreneurial teams  Optimize time and funds  Produce quantitative results  Increase integrated studies  Improve success GEMINI Framework

Gemini (Geo-Engineering Modeling through Internet Informatics) is an interactive, integrated Website designed to construct real-time geo-engineering reservoir models. Information assembled form the Website or uploaded by the client (one person or a team) will be analyzed with an extensive suite of web-accessed analytical software using intelligent interfaces and tutorial support to accomplish project development. Project can range from regional to local and span problems from complex to simple.

Gemini Web Programming Java Applets –Graphical User Interfaces Java Servlets –Bridge between Applets and Database & Files ORACLE Database & Electronic Files –Well Header & Core Library Database Tables –Digital LAS Files

Gemini User/Project Area Java Applet Gemini User Creates Personal Work Area on Kansas Geological Survey’s Database. Gemini User Identifies Region of Interest, i.e. Oil & Gas Well Location and Formation Gemini User Selects Oil & Gas Wells. Gemini User Saves their Data and Work in Kansas Geological Survey’s Database.
