Corrosion issues recorded during start-up (nitric acid attack on third Corrosion issues recorded during start-up (nitric acid attack on third compressor stage) solved by :

- Lower cooling at DCC unit (30°C instead of 50°C) - Slight increase of the suction temperature

- Recycling dry CO2 at the inlet of compressor - Recycling dry CO2 at the inlet of compressor - Improvement of gas/liquid inter stage separators  No more issue

SUB-SURFACE FEEDBACK MONITORING:

FOCUS ON THE PILOT PERIOD

 Static reservoir pressure is increasing due to CO₂ injection. The reservoir pressure increase is as per the predictive model.

 Long term wiseg

CO₂ accumulates in low points of the reservoir, and CH₄ rich gas flows back up below the cap rock

CO2 remains primarily in the gas phase (minor dissolution / mineralization)

INJECTIVITY INDEX JANUARY 2010 TO JULY 2012 FEEDBACK

 There is no evidence of increasing or decreasing injectivity index

 In line with geochemistry studies , no modification of reservoir matrix

CONCLUSIONS

 Obj ti 1 Th t h i l f ibilit d li bilit f i t t d h C b

CONCLUSIONS

 Objective 1 : The technical feasibility and reliability of an integrated onshore Carbon Capture and Storage scheme for steam production at a reduced scale has been proved.  Objective 2 : Operational experience and data to up-scale the oxy-combustion

 Objective 2 : Operational experience and data to up-scale the oxy-combustion

technology from pilot (30MWth) to industrial scale (200MWth) are acquired. For CO2 from combustion in O&G sector, current cost evaluations for capture units of industrial size are still high

size are still high.

 Objective 3 : Reservoir and well performance are in line with the models. The demonstration of the site integrity and absence of environmental impact is done.

 Objective 4 : The monitoring program deployed at Rousse is very large and innovative. New tools have been successfully tested. The “optimal” long term post-injection

it i l i ll d t h i ll i bl i b i d fi d b d i k

monitoring plan economically and technically viable is being defined based on risk analysis update. It will have to be validated by French Administration.

 Positive public perception : “Transparency” in communication with local communities  Positive public perception : Transparency in communication with local communities

is one of the key factor to reach the public acceptance. It remains a permanent “concern” to be taken into account during the whole life of a CCS experimentation
