Total, oil and gas producer, is also producing CO2Total operates a daily production of more than 2,5 Bboe/d worldwideTotal supplies 2% of heating and automotive fuels used worldwideCO2 emissions to the atmosphere are about 60MtCO2 equivalent per year
Our objective is to keep strengthening our portfolio while contributing to energy efficiency and limitation of CO2 emissions

Beyong the current solutions to reduce greenhouse gases emissions :Existing facilities gas flaring reductionImprovement of existing and new facilities energy efficiency
Carbon Capture and Storage is considered as a breakthroughtechnology to be promoted for high CO2 emissions facilitiesSustainable development of Extra Heavy Oil (inc. mining, hot production and upgradingDevelopment of very acid gas fields (high CO2 content i.e. >10%)Large LNG facilitiesNon conventional ressources (oil shales)Large refining and petrochemical complex
Carbon Capture and Storage (CCS) is one solution to reduce our CO2 emissions from our facilities

Targets for implementing CCS to be prioritised: high to very high CO2 content gas fields orhigh combustion CO2 emission intensity

Capture technologies are progressing and O&G producers are keen to promote technologies that are adapted to their specific needs
Large CO2 networks implementation similar to large historical oil and gas networks development
For CO2 storage, there is a significant know-how within the industry forSite characterisationDrilling and injectivity issues Reservoir simulation, monitoring techniques ....
CCS is a promising solution for the O&G industry
ButThe site qualification and integrity studies workflow and tools have to be tested on real cases and within different geological contexts (i.e. pilots)
Commercial storage will be only developped in several incremental steps
Well integrity understanding is still to be improved
Public acceptance is not granted and there is minimum geoscienceknowledge within the public

CO2 pilot at Lacq general objectives
Demonstrate the technical feasibility and reliability of an integrated CO2 capture, transportation, injection and storage onshore scheme for steam production at a reduced scale (1/10th of future facilities)
Design and operate a 30MWth oxycombustion boiler for CO2 capture 50% improvement of CO2 capture energy efficiency50% reduction of capture cost compared to classical post capture technologies
Develop and apply geological storage qualification methodologies, monitoring and verification techniques on a real operationnal case to prepare future larger scale long term storage projects

Public consultation and dialogue requiredObjectives:
Share the opportunity of having such project in Lacq area and provide technical information of the Lacq pilot itselfProvide a better understanding of CCS technology context, issues and therefore promote the CCS technology deploymentHave all questions raised to propose answers at different stepsProvide information on short and longer term scientific follow up(dedicated scientific committee appointed with external experts) and monitoringHelp identifying project possible contribution to local socio-economic developmentDemonstrate transparency and provide access to relevant information
Total's approachOpen dialogue with all stakeholders upstream permitting processSeveral public meetings open to public in 2007Transparency and access to detailed informationLocal follow up committee with stakeholders during construction,injection and monitoring phase
