Transcription

1 European Unconventional Oil and Gas Assessment Funded by DG JRC and DG RTD via Horizon2020 The Project By Peter Britze GEUS 40 Years Listening to the Beat of the Earth

2 Objectives European Unconventional Oil and Gas Assessment () is an inventory of existing published knowledge on oil and gas resources in Europe. The project will: Compile data from the European countries Define a common resource assessment methodology Assess European gas and oil resources Make results available in an interactive GIS system Duration: September 1 st 2015 to March 31 st 2017

3 National Geological Surveys participating in the project Information on gas and oil resources for 26 countries are included in. Germany (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) is not a member of the 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.

7 Ranking of gas and oil Shale ranking/pre-screening criteria used. From task 2b report.

8 Basin classification according to ranking Basin classified according to the ranking/prescreening criteria. See Figure 3 for definition.

9 Overview of all 21 EU basins Outline of plays identified within the project. From task 7b report.

10 Shale Gas and Shale Oil in place resources in Europe From Task 7b report.

12 map compared to EIA map Overview of all 21 EU basins with outline of plays identified and classified within the project compared with one of the existing gas and oil maps.

13 Conclusions 82 hydrocarbon bearing formations within 21 countries were assessed for their resource potential. A stochastic volumetric assessment could be carried out for 49 formations. 15 hold both gas and oil resources, 26 only gas resources 8 only oil resources

14 Conclusions cont. The participating NGS in the project provided public data and information available from their respective countries. Common description template developed by the project team members. A full bibliographic reference database >240 references comprising the current state of the art of scientific research of European gas and oil.

15 Conclusions cont. The total resource estimation (P50) for all assessed formations in Europe amounts to tcm of gas and 31.4 billion barrels of oil in place. All analytical results delivered into an EGDI compliant GIS database All results are feed into the OpenECHO portal.

16 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 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 gas and oil in offshore basins Assessment of conventional HC resources CO2 storage potential assessment Coal resource assessment Heat storage assessment
