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

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

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

Assembly of Well Log Data
Query A select corebreaks and fractures
Minor Geology table
Query B select conductivity data
Query C select stratigraphy

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

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

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
