The Project
• Factors incorporated in determining risk level:
• Depth of well
• Amount of oil or natural gas produced per well
• Proximity to major cities
• Proximity to water sources:
• Streams
• lakes and reservoirs
• “principal aquifers” (defined by the USGS)
• Proximity to water sources with existing levels of pollution
Rationale and Potential Use
• Financial and practical purposes for federal/ state Departments of
Environmental Protection
Step 1: Refine the Variables
Step 2: Define “Dangerous” Criterion
• Water Sources:
• Streams:
• Close to stream = < 800 Meters (about
0.5 miles) from stream
• Lakes:
• On lake = < 1 Meter from lake
• Close to Lake = < 1610 meters (about 1
mile) from lake
• Aquifers:
• Close to aquifer = 0 meters from aquifer
• Internal Well Characteristics and Proximity to Major
Cities
• Deep well
• A well that is more than 12,000 feet deep
• High Producing well
• A one-mile radius with more than 129
producing wells
• Proximity to Major Cities
• Close to major city = < 32,200 meters
(about 20 miles) from major city
Step 3: Convert the Data Into The Same Projection System
• (WGS 1984 and NAD 80 USA Contiguous Albers Equal Area Conic USGS Version)
Step 4: Select by Attribute: All Wells into Deep Wells
Step 4 (Continued) Select by Attributes: All Wells into High Producing Wells
Step 5: Merge of High Producing and Deep Wells
Step 6: Use of Near Tool
Final Results
