Key points of discussion Ressource estimates
o IEA, USGS Geological potential for shale gas in Denmark
o Alun shale studies Present exploration in Denmark
o Total in northern Jutland and in northern Zeeland, drilling postponed from 2013 to 2014
Political situationo Parliament discussions and questions, Government internally
(Environment versus Energy) versus local authorities, NGO’s International collaboration
o EuroGeoSurveys GeoEnergy Expert Group, continuation from conventional assessments with USGS, new Baltic study, new EERA, future NAG??

Ressources, EIA 2011
o No discoveries in Alun shale
o Ressources estimated by U.S. Energy Information Administration in 2011.
o 23 Tcf !!!
o Totally unrealistic, poor work compared to e.g. USGS assessments

• 13 000 Km2 large prospectivie onshore area with Alun shale
• 50% with high expectations
• 32% in optimal depht range between 1.5 and 5 km
Potential for shale gas in Denmark
• High chance for some potential in the Alun shale, but no drilling yet
• Potential is restricted to relatively small areas in Denmark
• An assessment will be completed in 2013, and most likely updated after the first wells
• No numbers yet, but likely to be much lower than the 2011 EIA study
General comments on shale gas in Denmark

Shale Gas research subjects
• Understand processes critical to formation, accumulation, occurrence, and alteration of shale gas resourceso GEUS: traditional petroleum-related research
• Conduct scientifically robust assessments of those resources o GEUS: collaboration and data input
• Study impact of shale gas resource occurrence, production and use on environmental and human healtho GEUS: groundwater, surface, seismicity

Shale gas in Baltikum (USGS)
• Pilot study of gas potential of the Lower Paleozoic Shales in the Baltic Basin together with USGS.
• The overall goal with this pilot study is get an independent, scientific based, assessment of the shale gas resources in the Baltic Basin.
• It includes on- and offshore areas in the following countries: Norway, Sweden, Denmark, Estonia, Latvia, Lithuania, Poland and Germany.
• The European geological surveys has the data and knowledge on the specific shale stratigraphy, sedimentology, petrography etc.
• By combining the knowledge from each survey into a basin wide synthesis, knowledge is shared and the end product improved.
• USGS has built up, through their work in the US, a vast experience in assessing the shale gas potential.
• It is hoped that the pilot will develop into a study, that covers the entire Europe, financed by the Horizon 2020.
