Sažetak
Carbon capture and storage is becoming a critically important part of global warming mitigation efforts, and this trend is expected to continue, with more and more wells being drilled for this purpose. Well bores represent the most likely route for leakage of CO2 from geologic carbon sequestration. Maintaining mechanical integrity (internal and external) helps prevent the well and well bore from becoming conduits for CO2 migration out of the injection zone. The typical components of an CO2 injection well are casing, tubing, cement, and packer. These components are relevant to maintaining mechanical integrity and to ensuring that CO2 does not migrate upwards from the injection zone into USDWs ; therefore helping to ensure zonal isolation of the injected carbon dioxide. The paper describes well design, geochemical alteration of hydrated Portland cement due to supercritical CO2 injection, and mechanical integrity tests (MITs) as a means of measuring the adequacy of the construction of the injection well and as a way to detect problems within the well system.
