Carbon Capture and Storage (CCS) is a sequence of activities that comprises of capturing CO2, transporting CO2, and storing by injecting it into porous formation known as reservoir. CO2 resource may come from atmosphere, manufacture industries, or from subsurface, as an impurity from oil and gas production. <br /> <br /> <br /> Main issue of this activity is well integrity, which the fluid itself has corrosive characteristic, this increases the complexity related to corrosion. The existing injection well candidate. Well X, is a conventional exploration well which is temporarily abandoned. To make sure the feasibility of this well to be converted to CO2 injection well, series of studies were done related to well integrity. Previous study shows that with current specification, Well X with carbon steel material specification is not proper to be converted as CO2 injection as the corrosion rate to be encountered is very high, thus, tubing with Corrosion Resistant Alloy (CRA) specification is required. <br /> <br /> <br /> This thesis covers discussion about material feasibility and selection for tubing that will be evaluated using ECE® software, the standard refers to ECE® and ISO 15156-3 evaluation rules. Well components namely wellhead, packers, nipple, valves, and seals, are selected refers to American Petroleum Institute (API) Spec 6A, API Spec 5CT, API Spec 11D1, API Spec 14L, API Std 622, and API Std 624 literatures. Proposed method of material selection optimization consist of segmenting the well into several segments and material selection that will be done discretely. The idea is different, which the popular method is evaluating material based on well optimum condition. Correction on injection pressure on previous study will be explained in this thesis. <br /> <br /> <br /> Optimized Corrosion Resistant Alloy (CRA) selection based on ECE® evaluation rule recommends the application of 13 Cr as minimum specification for tubing material, while ISO 15156-3 evaluation rule recommends the application of 22Cr Duplex. In addition, according to API Spec 6A, the wellhead also must be upgraded from BB class to HH class.
