2Summary
- Simple concept
- Less simple in reality
- GIS is indispensable
- GIS-ready data very helpful
- Presentation is critical
- But it can be done!
3Proprietary GoM Dataset
- Small but deep dataset
- Small number of rows (prospects)
- Large number of attributes
- Spatial distribution also very important
- Attributes need to be apportioned by spatial
relationships - Example Volumes by ownership from leases
4Multi-variate dataset

5GIS Data AutomationSimple concept
Ownership based on geometry
Intersection
Blocks Leases
Prospect Outlines
6GIS Data AutomationSimple concept
Each lease can have multiple owners with varied
working interest
Owner 1 Owner 2 Owner 3
60 30 10
Aggregate ownership recalculated with changes in
outlines and leases
7Simple ?
- "I have yet to see any problem, however
complicated, which, when you looked at it in the
right way, did not become still more
complicated." -- Poul Anderson
8GIS model reality (not so simple)
Gather leases from state waters and onshore and
make them look like GOM3s federal offshore leases
Aggregate leases with blocks to capture open
areas where there are no leases
Pre-select only leases and blocks that intersect
prospect outlines to enhance performance
Calculate new category attributes (e.g.
Deepwater vs Shelf) and delete unwanted
attributes to reduce clutter
But it works!
9Now what?
- Ok, the calcuations are done
- What do we do with them?
- How can the trends, patterns, salient facts, and
interrelationships be communicated?
10Edward Tuftes Principles
- Show all the data
- Present lots of visual detail
- Show context
11Applying Tuftes Principles
- Poster not slides
- Large format
- Lots visual detail
- Non-linear
12Show your data
- "1. Never tell everything at once." --

15The Joys of Automation
- "The computer allows you to make mistakes faster
than any other invention, with the possible
exception of handguns and tequila." - Mitch
Ratcliffe
16Integration of data with GIS
Bathymetry contours
Leases
Fields
Air photos
Pipelines Platforms
GDE maps, Potential fields, playfairways,
competitor wells etc.
Shipping channels

18Final thought
- "Courage is what it takes to stand up and speak
courage is also what it takes to sit down and
listen." -- Winston Churchill
