What is GIS?

• GIS is computer software that links geographic
  information with descriptive information.
• GIS technology can integrate georeferenced
  imagery as data layers and link them to other
  data sets to produce geospatial representations
  of data.
• GIS can also help users anticipate future
  outcomes by depicting regression analysis for
  forecasting future events and processes. i.e.
  site hazard assessments.
• The ability of GIS to manage, correlate, predict,
  model, and share geographic information makes GIS
  an essential analytical tool.

3
Why Use GIS?

• Multiple data sources stored in a variety of
  formats in many locations.
• EORI Database
• WY Oil and Gas Conservation Commission
• WY Geographic Information Science Center
• WY Geographical Association
• WY Geographic Information Advisory Council
• WY State Geological Survey
• Data needs to be integrated so that it can be
  analyzed as a whole and on the basis of spatial
  relationships.
• Spatial data can then be leveraged to make
  critical business and planning decisions.

GIS Tasks

• General purpose GISs
• essentially perform five
• processes or tasks
• Input
• Manipulation
• Management
• Query and Analysis
• Visualization

Three Views of a GIS

• The Database View
• Not easy to interpret.
• The Map View
• Worth a thousand words.
• The Model View
• Derives new data sets from existing datasets.
• KEY CONCEPTS
• Maps and database are interactive.
• Multiple databases can be linked and related.

Needs Assessment for GIS

• Inventory of existing resources.
• Consulting with staff and outside resources.
• Potential applications of GIS technology.
• Database and system design.
• Implementation plan.

8
Implementation Plan

• A 1 year period divided into two 6 month phases.
• Phase I will include the following
• QA/QC data.
• Build geodatabase.
• QA/QC data in GIS.
• Base map design.
• Build database query tool.
• Design a volumetrics calculation tool for a
  single reservoir.
• As the GIS gets utilized, the need for additional
  tools will arise. Any data needed for those
  tools will be quality controlled and imported
  into a geodatabase.

9
Implementation Plan

• Phase II will include the following
• Development of the following tools
• Scoping tool.
• Modeling tool.
• Hyperlink tool.
• Photolink tool.
• Monte Carlo simulation.
• Electric document management system (eDMS).
• Further work on volumetrics calculation tool for
  multiple reservoirs within a field.

10
Possible Plans for the Future??

• Work in conjunction with other resources in order
  to provide the best enhanced oil recovery
  opportunities for the state of Wyoming.
• RMOTC Jeanette Buelt
• WYGISC Jeff Hamerlinck, Jim Oakleaf
• WYOGCC Rick Marvel
• Wyoming Pipeline Authority Brian Jeffries
• Internet mapping on EORI webpage

GIS for Enhanced Oil Recovery

• Enhanced decision making.
• Better understanding of the spatial distribution
  of reservoir characteristics and potentially
  their origin (pure research).
• Identify spatially related entities.
• Proximity to required resources (low-salinity).
• Proximity to other reservoirs with matching
  characteristics/potential EOR methods
  (sink clustering).
• More than 70 of all oil companies use GIS.
