European Unconventional Oil and Gas Assessment
The
EUOGA
Project
Funded by DG JRC and DG RTD via Horizon2020
By Peter Britze GEUS
EUOGA Objectives
European Unconventional Oil and Gas Assessment (EUOGA) is an inventory of existing
published knowledge on shale oil and gas resources in Europe.
The project will:
• Compile data from the European countries
• Define a common resource assessment methodology
• Assess European shale gas and oil resources
• Make results available in an interactive GIS system
Duration: September 1st 2015 to March 31st 2017
National Geological Surveys participating in the EUOGA project
Information on shale gas and oil resources for 26 countries are included in EUOGA . Germany (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) is not a member of the EUOGA project consortium. The status and categorisation given for the situation in Germany reflects the authors judgements based on public documents, especially the report of Schieferöl und Schiefergas in Deutschland (BGR 2016) and personal communication.

Conclusions
• 82 hydrocarbon bearing shale formations within 21 countries were assessed for their resource potential.
• A stochastic volumetric assessment could be carried out for 49 formations.
15 hold both shale gas and shale oil resources,
26 only gas resources
8 only oil resources
Conclusions cont.
• The participating NGS’ in the EUOGA project provided public data and information available from their respective countries.
• Common description template developed by the EUOGA project team members.
• A full bibliographic reference database >240 references comprising the current state of the art of scientific research of European shale gas and oil.
Conclusions cont.
• The total resource estimation (P50) for all assessed shale formations in Europe amounts to 89.23 tcm of gas and 31.4 billion barrels of oil in place.
• All analytical results delivered into an EGDI compliant GIS database
• All EUOGA results are feed into the OpenECHO portal.
Recommendations
A consistent and reliable assessment of the European geo-energy resources are the basis for making informed social, political and commercial decisions.
Thus we recommend (through e.g. GeoEra, which will pursue this activity further)
• Maintain and develop the data base build in EUOGA and applied into OpenECHO.
• The same methodology developed in EOUGA is implemented in future Geo-energy assessment studies. These geo-energy topics are:
Geothermal resource assessment (including EGS)
Resource assessment of shale gas and shale oil in offshore basins
Assessment of conventional HC resources
CO2 storage potential assessment
Coal resource assessment
Heat storage assessment
