  2. Drill Site Merits of One Copy Storage Laboratory Mapping Data Mapping Data Drill Site Field Crew Laboratory Field Crew BH logs Sample Results Data Management System Analysis Analysis Geophysical Data CAD/GIS Analysis Analysis Analysis Reporting Reporting • DMS • integrated data analysis • automated error trapping • single copy data storage • Traditional Data Handling • Isolated data analysis • limited error trapping • duplicate data storage

  3. VIEWLOG DMS Component Overview Data entry and Reporting Log Editor Mapping X-t Graphing Cross Sections 3-D SQL Queries for Filtering, Processing and Analysis Meta-Data(contouring parameters, colors, etc.) Open, SQL-based Relational Database

  4. Open, SQL-based Relational Database DMS User Groups • Data Entry • Technicians • Scientists • Managers • Clients Web Browser Reporting Module Data Entry Module VIEWLOG Component:

  5. VIEWLOGGeologic Data Management System

  6. VIEWLOG Design Goals • Integrated display and interpretation tools • GIS, with intelligent, geo-science based, data objects • Not just display, but meaningful interaction with the data • Scalable interpretation tools, from a single fracture to an entire watershed • Open, flexible, database design, with dynamic interaction with any table or query • Designed as a GIS/CAD companion tool VIEWLOG Systems

  7. Integrated Visualization & Analysis VIEWLOG provides integrated data management, visualization and analysis functions through the following tools: • Well Editor • Map/Drawing Editor • Cross Section Editor • Real-time 3-D Visualization Module

  8. Borehole Data Editor • Well Editor used to dynamically integrate well measurements, such as: • geology • geophysics • interval measurements • packer test results • fluid sample data • core photographs • Templates ensure consistent standard presentations

  9. Example Composite Borehole Log Stratigraphy filtered from Major Geology table in database Core Features filtered from Minor Geology table in database Geophysical Traces filtered from geophysical data files K Data filtered from Well Test table in database

  10. Assembly of Well Log Data Query A: select corebreaks and fractures Minor Geology table Query B: select conductivity data Query C: select stratigraphy Major Geology table VIEWLOG Well Tests table Geophysical Data files Composite Well logs

  11. Interpretation at Various Scales Zoom for detailed image of core

  12. VIEWLOG Map Editor • Geologic objects (boreholes, units) are stored as high level “intelligent” objects, with integrated data, processing and display properties • GIS style multi-layer working environment • DXF/CAD compatible • Page view / world view coordinates for enhanced printing “viewport” control

  13. Intelligent Map Objects • High level map objects, including: • Boreholes • Grids • Surfaces • retain links to the source data in the database

  14. Object Layering • Layering allows overlying of air photos, CAD drawings, posted data and kriged contours for rapid analysis • Dual coordinate (page/world) mapping system with easy Viewport window control

  15. Cross Sections • All interpretation performed in true x,y,z coordinates • Dynamically change vertical exaggeration • Direct links to data objects makes section updates easy • Includes drawing layer control and dual coordinate (page/world) system

  16. Cross Section with Water Levels Water table from water level data from all wells Geologic Structure krigged and contoured from well data Boreholes along cross section line Water table elevations

  17. Geological Modelling

  18. Krigging Features • Contouring Controls • for map & cross section views • contour intervals • colour formats • Grid / Krig Controls • grid construction • krigging order and variogram slope control

  19. 3-D Visualization

  20. 3-D Transparent Layers

  21. Interactive Cut-away Mode

  22. Fence Diagrams

  23. Integrated Flow Modelling

  24. VIEWLOG Internet Server • A browser independent, VIEWLOG client • VIEWLOG runs as an out-of process ActiveX Server using ASP and Microsoft IIS 4.0

  25. VIEWLOG Server: Sections • Web Server includes full support for cross sections

  26. VIEWLOG ActiveX Control • Control VIEWLOG as a programmable ActiveX object in other applications

  27. DMS Conclusions

  28. WHAT MAKES A DMS WORK? Structure: • Effective design of data storage structure Tools: • Tools to merge all data streams for storage and QA • Processing and analysis tools • Tools to retrieve, integrate and visualize data

  29. Benefits of a VIEWLOG Data Management System • One copy data storage for all users • Powerful searching tools to assemble data sets for analysis and interpretation • Coordinated visualization tools necessary to integrate and interpret earth science data
