Few data about permeability of Upper
Triassic reservoir. Excellent cap-rock,
(Dagorda Formation), but unsure about the
quality of the reservoir.
Lower Cretaceous is a good reservoir,
However, uncertainty about the cap-rock

Seismic exploration
However, there is not a scientific/technical community permanently engaged in CCS
R&D! Having concluded their tasks all researchers went back to their primary line of
research.
A CO2 injection pilot could represent a lighthouse project, an opportunity
to consistently build capacity amongst a body of young researchers.
Are seismicity and induced seismicity a problem?
Seismic hazard higher along the
southeast coast - Central and
South Lusitanian basin and in
the central and west Algarve
basin.
Porto
Eurasia and Africa plate
boundary south of Algarve
basin
SPAIN
Many active faults in the same
areas.

Are seismicity and induced seismicity a problem?
Seismicity and induced seismicity can become showstoppers for CCS in
Portugal unless it is clarified their importance – likely to be central issue
to public opinion.
Can we add value to other pilot sites in Europe?
Highly compartmentalized reservoir –
tectonics and structural geology play a role.
Challenge to define the boundaries and to
study pressure build-up;
Structure map – top of
the Triassic reservoir
Can we add value to other pilot sites in Europe?
Highly compartmentalized reservoir –
tectonics and structural geology play a role.
Challenge to define the boundaries and to
study pressure build-up;
- passive seismic monitoring, time-lapse ambient
noise interferometry, time reversal imaging using
microseismic events – techniques being
developed to characterise reservoirs and
monitor CO2 plumes.
An open laboratory to study the effects
of natural and induced seismicity on the
safety of the storage complex, and as
tools for characterize and monitoring, as
well as for studying complexities of CO2
injection in highly compartmentalized
reservoirs.
A phased approach
The concept of emerging site in the Euroscoops proposal was interesting
• time to build expertise;
•knowledge sharing from other pilot sites
investment costs are high, even for re-entering a well - best to apply to different funding
mechanisms for different phases
Phase 1
• Laying the
scientific basis
and building
expertise
• 2014 - 2016
Phase 1I
• Injection well and
reservoir
characterization
• 2016-2017
Phase III
• An open
laboratory
• 2018 onwards
Phase 1 – Laying the scientific basis (2014-2017)
FCT (Portuguese Foundation for Science and Technology) scientific project. 2-3 years
projects, with maximum budget from 200 k€ to 500 k€. Norwegian funding also
required, at least to cover the engagement of Norwegian partners.
9 Site qualification procedures (SINTEF?)
9Background data, monitoring of natural seismicity - monitoring networks.
9Assessing existing boreholes – downhole geophysics - to identify if any of the
boreholes is suitable for reopening. (STATOIL , SINTEF?)
9Static modeling and seismic model of the study area (SINTEF?)
9Simulating the effects of CO2 injection in induced seismicity and of natural seismicity in
the storage complex. (SINTEF?)
9Natural and induced seismicity as a tool for reservoir characterization and monitoring.
(STATOIL?)
9training of 3 grantees, (site qualification and static model, downhole geophysics and
monitoring, and on dynamic modeling of CO2 injection). (SINTEF?, STATOIL?)
Phase II – Reactivating an existing borehole and
reservoir characterization (2016-2017)
More costly than phase I, objectives probably not within the scope of a FCT project, but more
within the spirit of EEA grants or Norway grants
Works in this phase would include:
9Reentering an existing borehole (or if none suitable drilling a new borehole) (STATOIL?)
9Reservoir characterization by 3D seismics; (SINTEF?)
9 Storage complex characterization (hydraulic, mineralogical, pressure, geothermal, etc.
(SINTEF?)
9Monitoring equipment installation in the reentered borehole (STATOIL?)
9First induced microseismicity experiments would be made with hydraulic testing.
9Training of grantees – reservoir engineer and monitoring
9Public engagement plan
9Establishment of a research group/unit focused on CCS.
Phase III – Open laboratory (2018 onwards)
From 2018 onwards - full scale implementation.
9Deployment of the monitoring plan and drilling monitoring boreholes,
9CO2supply,
9construction of surface facilities for compression and injection,
9injection of CO2;
9 The programme for R&D on risk factors associated to natural and induced seismicity
9 development of site characterization tools
9 Public engagement.
Would possibly require a larger consortium, involving several European partners, much
like the Euroscoops proposal, and an application for an international funding
programme, possibly Horizon 2020.

High risk / high gain pilot project; could
develop into for a larger scale demonstration
project.
Highly compartmentalized, pressure build-up a
major subject of research
Excellent cap-rock conditions,
Focused on research that could be
extrapolated to offshore conditions
Would characterize the two main reservoirs
and cap-rocks that occur offshore;
Area is much less populated.
Suitable conditions for studying natural
seismicity and induced seismicity effects.
monitoring techniques could be more easily
implemented.
If cap-rock of Lower Cretaceous reservoir) is
proved adequate, would demonstrate that
Portugal can store up to 200 years of its
emissions.
Negative

‐
Considerable risks of not
finding
adequate
permeability as little is
known
about
the
reservoir in depth.
The Lower Cretaceous
reservoir would not be
tested in the area since it
outcrops.
Characterize a place not
to
be

for
demonstration in the
future.
Partners (phase I and II)
•Universidade de Évora
•LNEG
•SINTEF
•STATOIL
•DGEG?
•Stakeholders?
Short term action
•Start planning to write the proposal for phase I (FCT call likely to
be published soon (last year deadline was June)
•Identify sources of funding for Norwegian partners;
•Engage with DPEP to ensure access to existing boreholes and
data acquired in 2011 and 2012.
•Ongoing EEA and Norway grants programme finishes in 2014. If
there is going to be a new one, contacts need to be made to
include CCS in Portugal as a thematic priority.
•Negotiate with FCT a line for a call specific on CCS.
