5.Conclusion Remarks (1/2)

Tai-power’s Road Map for Carbon Sequestration Pilot Project is already set and aimed to complete in 2017.j y p

Core study is regarded as an important issue and abundant cores will be used to ensure the data confidence.

History matching works will be employed when upcoming injection test of CO2 begins in 2016.

Risk assessments play an crucial role to the public acceptance Risk assessments play an crucial role to the public acceptance in early phases of Tai-power’s carbon sequestration in deep saline aquifer. On-going efforts are being taken inside project.q g g g p j(to be continued)
