TOTAL conducts the first French pilot to demonstrate the technical feasibility and reliability of an integrated CO2 capture, transportation, injection and storage scheme from a boiler at a 30MWth scale. This pilot entails the conversion of an existing steam boiler into an oxy-fuel combustion unit, oxygen being used for combustion rather than air to obtain a more concentrated CO2 stream easier to capture. Then CO2 stream is compressed and conveyed via pipeline to the Rousse depleted gas field, 29 kilometers away, where it is injected into a deep carbonate reservoir. CO2 injection started earlier 2010 as all the proper official authorizations have been given. An appropriate monitoring plan is conducted to check the site integrity and storage performance. A preliminary baseline, conducted one year before the start of the injection is used as reference to detect any anomalous behavior which could be linked to any CO2 leakage. The aim of this paper is to present, the main lessons learned from the monitoring of the CCS pilot site of Lacq, after more than two years of injection and a year pre-injection baseline, in terms of monitoring-models offsets, security and risk analysis.
