VIEWLOG Borehole Data GIS VIEWLOG Systems

2 Earthfx Approach Data Management Visualization Analysis Modelling

3 Earthfx DMS Component Overview Open, SQL-based Relational Database Log Editor Mapping Cross Sections X-t Graphing SQL Queries for Filtering, Processing and Analysis MODFLOW Data entry, Reporting, Tracking 3-D Sitefx VIEWLOG Earthfx Data Model VIEWLOG/WebServer

4 Data Management Visualization Analysis Modelling 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

5 Visualization Data Management Visualization Analysis 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

6 Analysis Data Management Visualization Analysis 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

7 Modeling Data Management Visualization Analysis 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
