Enhancing CO2 Injector Well Performance with GRE Lined Tubing: A Technical Evaluation

Abstract Carbon capture and storage (CCS) technology has emerged as a pivotal strategy in mitigating greenhouse gas emissions and combatting climate change. An integral component of CCS systems is the injection of captured carbon dioxide (CO2) into geologic formations, often via dedicated injector wells. The efficiency and safety of these injector wells are of paramount importance. This technical paper presents a comprehensive study on the application of Glass-Reinforced Epoxy (GRE) lined tubing to enhance the performance and longevity of CO2 injector wells. The use of GRE lined tubing has gained traction in various industrial applications due to its exceptional corrosion resistance, mechanical strength, and long-term durability. This paper outlines the material properties and manufacturing processes associated with GRE lined tubing, emphasizing its suitability for the harsh conditions encountered in CO2 injection wells. Key aspects of the study include: Material Selection: A detailed analysis of GRE lined tubing's chemical resistance and mechanical properties in the context of CO2 injection environments, highlighting its advantages over traditional materials. Corrosion Resistance: A comprehensive investigation into GRE lined tubing's resistance to CO2-induced corrosion, offering insights into the potential for reduced maintenance and increased operational lifespans. Hydraulic Performance: Assessment of the tubing's hydraulic properties, including flow rate and pressure drop characteristics, to ensure efficient CO2 injection. Long-Term Reliability: A discussion of GRE lined tubing's resilience to cyclic loading, temperature fluctuations, and exposure to high-pressure CO2, demonstrating its suitability for extended service life. Safety Considerations: An examination of safety implications and regulatory compliance associated with using GRE lined tubing in CO2 injector wells, focusing on leakage prevention and environmental protection. Case Studies: Real-world examples and case studies showcasing successful implementations of GRE lined tubing in CO2 injector wells, highlighting improved operational efficiency and reduced downtime. The findings from this study offer valuable insights into the benefits of employing GRE lined tubing in CO2 injector wells. By enhancing corrosion resistance, improving hydraulic performance, and ensuring long-term reliability, this innovative material can contribute to the efficiency and sustainability of CCS systems, ultimately advancing efforts to reduce carbon emissions and combat climate change.
