Earth Vision addresses the connectivity issue (September 1996)

California-based Dynamic Graphics Dynamic Graphics has just released version 3.1 of its EarthVision integrated family of geospatial analysis software for the earth sciences.

Highlights of the release, according to the company, are the new mapping and export capabilities from the Geologic Structure Builder (GSB) and the Geostatistics module which incorporates capabilities from Stanford University's GSLIB geostatistics software library. Launching the new product, Art Paradis, company president, said that one of the ways Dynamic Graphics was working to make its clients' lives easier was to address the connectivity issues between the industry's leading 3D reservoir models and other widely used software. Paradis claimed "Moving EarthVision models to the simulation phase of a project should be significantly smoother with our new GSB export capabilities." GSB constructs 3D models of complex layered, faulted and non-faulted areas based on scattered data, surfaces, 3D grids and a fault hierarchy. GSB structure and property distribution models can now be exported to formats suitable for upscaling/upgridding software including the Grid program from GeoQuest Reservoir Technologies and the GridGenr and GeoLink programs from Landmark. Complex horizons from GSB models can also be exported to 2D grids providing a link for post-processing of precise EarthVision model components using other software.


The geostatistics model incorporates the ordinary kriging modeling algorithm from Stanford's GSLIB geostatistics software library. Graphical data preview and variogram generation capabilities are available to set up and optimize model calculation. Variance models can be calculated to help quantify model accuracy, this in addition to the 2D and 3D models produced.

Well planning

Dynamic Graphics has added two visual techniques to the EarthVision3D viewer for well planning activities. The Snap to Surface function provides the 3D co-ordinates of a feature of interest picked on a model surface. The Extend Well function calculates the relative azimuth, relative inclination and extension distance from the endpoint of an existing well to a graphically-picked extension point. Another analytical feature provides isochore maps based on 3D GSB models offering information for reserve calculations.


Other enhancements being promoted by the company include a significant increase in project size to 2 million input scattered data points and 2 million 3D grid nodes, a pre-release of a new 3D viewer which is said to provide up to 300% improvement, additional local faults for intermediate surfaces calculated by GBS Horizon Gridder, new formula, processor functions, perspective views of 2D surface-based projects and the EarthVision Notebook, described as an interactive program that can store a detailed record of processing steps and workflow during a project. The release is available immediately for Silicon Graphics, IBM RISC System/6000 and Sun workstations. The new geostatistics module is initially available for Silicon Graphics and IBM and will be ported to other platforms in due course. The four basic systems are priced in the US from $12,500 to $70 000. Any system can have a Network License Controller module which allows a software seat
