Report WG1 - progress achieved so far, next steps
ANNUAL CONFERENCE European Science and Technology Network on Unconventional
Hydrocarbon Extraction
Working Group 1 (WG 1):
Exploration, demonstration and production projects in the EU
23rd February 2016
Brussels, Rue Froissart 36, Centre Borschette
Grzegorz Pieńkowski, Alwyn Hart
WG1 was created in order to create a database on
exploration, demonstration and production projects in the EU • GOALS:
• A comprehensive list of projects in the EU
• A comparative analysis based on the data collected.
For preparing the output, the WG1 was split into the following Tasks:
(A) Collation of existing and where relevant, planned unconventional
hydrocarbon exploration/production projects in the EU,
(B) Comparative assessment of environmental data gathered in the
database, including comparison at international level (beyond EU)
(C) Identification of gaps and R&D needs, building on assessment of
project specific data carried out,
(D) preparation of an annual conference and report

SHALE GAS - well-by-well dataset (well that have been drilled, with licenses
granted, fractured wells are marked; source – governmental)
Other well-specific datasets (composition of fracturing fluids) – International Association of Oil and Gas producers:
http://www.ngsfacts.org/findawell/ and OPPW website: http://www.opppw.pl/en/fracturing_fluid_composition/23
Recommendations/conclusions (PL reports): • Polish government and regulatory entities concluded on the basis of site specific study
(environmental impact assesment) , carried out at 7 shale gas exploration wells, that
hydraulic fracturing process does not pose long lasting, significant impact on environment, if
existing technical rules are observed.
• Special concern should be put on waste management, as high quantities of drilling wastes,
flowback and produced water might pose hazards to natural environment on site and
elsewhere.
• Ensuring safety of the environment and sufficient public perception and safety in production
areas will require an adequate control of technical operations and the establishment of
uniform, independent, long-term monitoring of the environment. Further
exploratory/production operations should be preceded by:
- site specific water supply study (incl. alternative water sources)
- baseline status of surface and groundwater (quality and quantity),
- background concentrations of methane in groundwater,
• baseline concentrations of methane in soil gas – accurate measurement of thermogenic
methane emission still remains difficult. Differentiation between different sources of
thermogenic methane is even more difficult, if possible at all
Environmental impact assessment can be seen as assessing the consequences and
results following certain action and event – thus, such approach can offer verification of
environmental risk assesment.

UK Environment Agency, Onshore Oil & Gas Sector
Guidance, 2015
EU still in early exploration phase
EU shale drilling activity remains low
Drilling in the EU accounts for less than 3% of the shale wells drilled outside
North America
Hydraulic fracturing of horizontal wells has been limited
Main activity still in Poland, in future better perspectives in the UK, possibly
development in Germany and Romania
During the Working Group meetings it was noted that there is still an issue of
common language, particularly in the debate between NGOs, science and
industry, because some words used can be very misleading in a different
context – for example: definition of well integrity and its failure, magnitude of
eathquakes, mixing different types of subsurface activities.
GENERAL CONCLUSIONS:
THE WG1 ACHIEVEMENTS:
The Workgroup 1 deliverables are products of the dialogue among Network experts and the collaboration between several internal services of the Commission regarding various environmental aspects of hydraulic fracturing, or by collating disparate information from public domain or grey literature.
There were created the following:
• The list of shale gas/oil exploration wells in EU – organised in a consistent manner having the well as central unit of assessment
• Preliminary list of tight gas and CBM (to be further developed); European unconventional hydrocarbons wells which was partially populated with the latest available information
• Collection of relevant references, organized in three cathegories: databases, reports, peer-reviewed papers. Additionaly, databases were complemented with two working worksheets (for user input), focusing on the environmental studies and relevant baselines/monitoring as established in the Commission Recommendation (2014/70/EU) – a matrix with various parameters to be filled in
• A GIS project assembling the information from all input files (wells list, environmental worksheets, database) into a geodatabase and presenting the content on geo-referenced maps; an online interactive database interface allowing basic operations like filtering, creating various infographics or conduct statistical analysis to be performed.
