4. Technology for a better society
• Methodology:
• Reliable sources of information
• Task force
• Several iterations with the working
group
SINTEF (Norway, Lead), IEN (Poland),
UKERC (UK), ECN, TNO (The Netherlands)
and LNEG (Portugal), Aarhus University
(Denmark), Helmholtz (Germany) and
lately IFPEN (France).

Working group participants and methodology

5. • EERA should form a JP on Shale Gas to ensure
• a common and independent EU knowledge and competence base
• to draw on for politicians and decision makers

VERSUS

9. • The JP has been unanimously accepted by all EERA ExCo
members with a special positive remark by the French
representative about the support on behalf of the French
government.

13. Common characteristics of gas shale reservoir
Technology for a better society
www.eera-set.eu
Heat
flow
 Direct production from source rock
 Low permeability

14. Keys to success of shale gas in USA
 Several extended horizontal wells from one surface frame
 Hydraulic fracturing

16. Objectives of SP2
Improve the efficiency and the recovery from shale gas
reservoirs
• Production parameters
• Increased knowledge based on logs and few samples
• Controlled fracturing process with minimum fluid use
• Increased learning from ongoing production monitoring
