The urgent global need to mitigate climate change by significantly reducing greenhouse gas emissions has driven the adoption of innovative solutions in the energy sector. Implementing CCS/CCUS operations is one way the energy sector can contribute to cutting emissions. CO? injection is a core component of CCS/CCUS operations, aimed at reducing greenhouse gas emissions by storing CO? underground. Well G, currently a suspended gas production well in the X Field, is planned for conversion into a CO2 injection well for Carbon Capture and Storage (CCS). Prior to initiating CO2 injection operations, several critical analyses must be conducted to assess the tubing's suitability, including corrosion rate, risk of failure, material selection, and tubing stress analysis. These evaluations are essential to ensure safe and seamless CO2 injection operations without potential issues. The tubing analysis indicates that the 5½” x 3½” tubing, made of L80 grade material with 13Cr, is deemed safe for CO2 injection at a rate of 59 MMSCFD, with a corrosion rate of 1.66 mm over a 12-year injection period. For enhanced material strength and durability, the use of at least Super 13Cr material is recommended. Tubing stress analysis confirms that the selected tubing, with its specified weight, grade, and connection, can withstand various loads and operational conditions. This study evaluates the feasibility of converting a gas producer well into a CO2 injection well for CCS operations.
