• Designed to be FULLY LINKED to a database– Only one copy of the data is stored: easy update/backup/tracking– Access, Oracle or SQL Server

• Open Database Design– Dynamically choose which tables and fields to display– Use Access and VIEWLOG at the same time (Alt-tab)– Add your own tables and fields– Includes a powerful, free, groundwater “Data Model”

• Powerful Borehole “Data Source” object– Ties together well header details, logs, well construction and geology

• Tabular data display, with 2-way interactive editing– Includes a query builder and a dynamic filter tool

Modelling

• Integrated Display, Editing and Processing environment• Extensive GIS functionality

– Full layer management– Dynamic (on demand) linking to shape files– Polyline attributes can be used to define grid cell properties– Completely grid independent property management

• All visualization display types– 2D GIS mapping, 2D Sections, 3D Real-time, 1D logs

• Very powerful cross section interpretation tools– Dynamic cross sections: shift sections/ change borehole offset– On-section layer picking and 3D horizon line drawing

• Extensive well log editing and processing capabilities– Support for borehole geophysics, logs, FW sonic

Modelling

• Powerful “Data Parameter” object for gridded surface management– Brings together database query, well source and all display properties– Open, unlimited number of data parameters – Project manager system for parameter organization

• Extensive grid data processing tools– Support for multiple grid definitions in one project (TMR)– All grids can be variable cell sized (MODFLOW compatible)– Support for huge grids (32k x 32k r x c)– Grid equation processor (including conditional equations and scripts)

• Powerful Constrained Gridding and Geologic Modelling– Merge picks, 3D constraint lines and manual contours– Powerful surface linking and conditional volumetrics– Extensive 3D variogram and 3D gridding– 3D Tinning

Modelling

• Completely grid independent model property assignment– Individual or group assignment of properties

– Full layer based polygon management

– Also support for “zone-based” parameters • Zone data read from database or spreadsheet

• Open “plug in” system for model input parameters– Change selected inputs, and compare multiple scenarios

• Powerful grid independent stream flow property assignment– Proven with models with over 70,000 stream segments!!

• Model output fully integrated with all database information
