The increasing demand for effective CCS solutions necessitates the development of robust well casing design for injection. This thesis emphasizes the critical parameters of grade, thickness, casing weight, and material selection. By assessing the unique challenges posed by the corrosive nature of , the thesis aims to establish guidelines for optimizing well casing integrity and performance in highpressure environments. To achieve reliable design, the study identifies suitable grades of steel to withstand harsh conditions associated with injection. Furthermore, the analysis includes detailed calculations of casing thickness and weight, ensuring that the selected design meets safety and operational standards. The result shows that there are 6 casing strings with each respective depth and pressure. The casing strings have diameter liner. Selected grade with X- N-80, 13 L- - -110, and -125. The material that is suitable for liners when subjected to corrosive components such as CO2, H2S, and water is Nickel-Chromium-Molybdenum Alloy.
