Shale Gas Analysis

These are notes from Shale Gas EIA Study

• Review of Shale Gas and Shale Oil
• Background
• hydraulic fracturing and horizontal drilling have greatly expanded the profitability of natural gas
• started to grow in 1950s
• mid 1970s partnership of DOE (Department of Energy) and GRI (Gas Research Institute)
• grew technologies
• large scale production in shale occurred with Mitchell Energy and Development Corporation
• EIA and NEMS(National Energy Modeling System) presented Shale in mid 1990s, only a game changer for the past 5 years
• Scope and Results
• shale resources 

• total 750 trillion cubic feet technically recoverable
• 86 percent located in northeast and southwest and gulf coast
• 23.9 billion barrels onshore in lower 48 states
• Major areas onshore current development
• Monterey, Santa Maria, San Joaquin Basin, Bakken and Eagle Ford
• Methodology
• INTEK shale report made from public company data and commercial databases
• Issues and Concerns
• gas and oil wells for shale are new and untested for long term production
• production located to sweet spots of highest production
• shale plays are very large only portions have been tested
• Can have more production with technical advances and untested methods
• Resource estimation still evolving
