• Green River Basin of SW Wyoming
• Approx 30 miles long by 5 miles wide
• 198,000 Acres• 80% of acreage is Federal BLM• 2nd largest gas resource in U.S.*
(20-25 Recoverable TCF)• 3,000 to 6,000 ft of highly
discontinuous, tight sand• Producing depths of 7,000 to
14,000 ft.

• Production Geologists• Rig Planners• Drilling Engineers• Surveyors• Permitting • Well Logging
We plan approximately 750 wells per year and drill approximately100 wells per year. Current unitization - 10 acre spacing (16 wells/qtr section)
5 acre pilots (32 wells/qtr section)
Well Planning & Execution Team

4/6/2009
Well Planning takes too much time(3-5 months per ¼ section-16-32 wells)
• Develop a standard process
• Transition from traditional methods (Excel, Canvas, MapTech)
• Provide timely access to decision support information
Well Planning is not integrated with other data or processes
• Provide dynamic information access
• Provide integrated data sources
• Provides access to other disciplines
Business Drivers / Solutions
4
4/6/2009
Well Planning has questionable accuracy
• Assure accurate and reliable data by utilizing a spatial component
• Provide high quality deliverables
Well Planning needs to be automated
• Accomplish more work with fewer resources
• Provide automated tools for time consuming tasks
• Empower users with intuitive interface

Data Created from Toolset1. Well Planning Dataset
Proposed Drainage EllipsesOrientation is based on induced hydrologic fracturesresulting in an elliptical rather than a circular pattern
Major/Minor Axis defines the elliptical pattern (4:1) based on micro-seismic information
Area is based on optimal production (10 acre vs 5 acre)
Target Areas – 80’ radius around well point
Proposed Wells – Standardized Well Name and StatusCall-outs – Require format = Distance from N/S & E/W Section Line
