State of the Art in Geothemal Field Visualisation

Abstract

FieldGL, a graphical three-dimensional (3D) inteface for the GDManager integrated geothermal database system is presented. The interÄace allows the user to interactively view and explore wells, data related to wells, and other subsurface information. It can also be used to view and graphically modify a computer model and then to view the results of a simulation. The interface is written with Borland Delphi and utilises the accelerated graphics rendering tools available in standard GLScene and OpenGL graphical libraries. As the interface library is object orientated it is readily extendable and has since been incorporated into the Automated Well Test and Analysis System (AWTAS) and WELLSIM softwares developed conjointly by PB Power, Genzl Division and UniServices. This library is an attractive alternative to existing 3D packages for displaying information within a geothermal field.
