Optimizing Carbon Capture and Storage (CCS) in Multiple Reservoirs: Advanced Completion Design with Flow Control Valves

Summary This paper investigates completion design options for Carbon Capture and Storage (CCS) wells, particularly focusing on multiple reservoir zones. It explores advanced strategies, such as the use of Flow Control Valves (FCVs), which challenge the industry’s conventional preference for simplicity. The study evaluates the project benefits and impact of complex completions aiming to enhance CO₂ storage capacity, reduce the Area of Review (AoR) extension, improve reservoir efficiency, and balance operational risks. Key analysis areas include: Challenges in CCS completion design Maximizing the capacity of multiple reservoir zones Project impact of advanced completions Risk management strategies Completion design workflow optimization. The paper advocates a paradigm shift in industry design practices suggesting that, in certain cases, advanced completions may offer superior outcomes, promoting more efficient and sustainable carbon storage.
