INTRODUCTION: WHAT DOES SCHUEPBACH ENERGY DO?
• Early history:
• Shale Gas in Marcellus (divested)
• Various shale gas projects in Europe:
• France (legal action)
• Switzerland (active)
• Denmark (technically unsuccessful)
• Current:
• Focus on conventional exploration:
• Spain
• Activities with focus on conventional exploration and, as a second step, possible unconventional
exploration (upside potential) (Parana Basin)
• Exploration in untested basins, or limited tested, where the conventional plays are much more
economic and feasible
• Unconventional plays are more difficult and expensive to prove; lack of equipment

IMPORTANT GENERAL AND TECHNICAL REMARKS
• Water:
• Very sensitive topic for the public
• Most people are of the opinion that - like air - it belongs to everybody
• Proper well construction isolates aquifer (conventional and unconventional wells)
• Fracing operations are well below the aquifer
• Percentage of water usage for fracing is minimal compared to other usages

LANDSCAPE AND FOOTPRINT
• Well pads with up to 16 horizontal wells
• Surface area needed for production facilities is only 0.02% of the drainage area of 16 wells
• Impact on landscape minimal compared to wind turbines

WHY IS SHALE GAS SO SUCCESSFUL IN THE US AND NOT IN OTHER COUNTRIES?
• Shale gas/shale oil was initially developed by independents rather than by
major corporations
• Accept higher risks
• “No gain without pain”
• Constantly applying and developing new techniques
• Availability of land
• Oil/gas rights belong to individuals (mineral owners, who are usually also
the landowner) and not the State
• Negotiations are conducted directly with the mineral owner rather than
the State
• Win – win situation; both sides make money (lease bonus + royalties)
• Availability of equipment
• State governments are familiar with gas/oil operations; regulations exists
• Willingness of the government to provide affordable energy and supply security
• Decreasing carbon is not the main objective

RESULTS IN THE US
• Drastic increase of reserves and production (liquids production have now surpassed Saudi Arabia and Russia)
• Increased employment opportunities
• Low energy prices (various industries returning to the US; increased manufacturing)
• Higher tax revenues
• Supply and security
EUROPE
13
• Compared to US:
• High unemployment
• High energy prices
• Supply and security problems
• What to do?
• Allow shale gas/oil production is one solution
• Focus on affordability and supply security, not on carbon foot print
• Provide a win – win situation for local governments and land owners in form of a royalty
• Streamline environmental permitting
• New techniques like propane fracing

Shale gas offsets declines in other U.S. supply to meet consumption growth and lower import need.

OPPOSITION
• Against fracing • 200,000 fracs per year in the States with no major environmental or health problem
• Against any hydrocarbon exploration/production • Natural Gas is a transition energy, much cleaner than coal
• Concern that a dramatic increase in oil/gas reserves extends the life of these reserves and decreases the incentive to find alternative energy sources
