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 Websiteor uploaded by the client (one person or a team) will be analyzed with an extensive suite of web-accessedanalytical 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.

GeminiWeb Programming
