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

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

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

Krigging Features

• Contouring Controls
• for map cross section views
• contour intervals
• colour formats

• Grid / Krig Controls
• grid construction
• krigging order and variogram slope control

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

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
