Comprehensive evaluation of carbon capture and storage (CCS) in X field, Vietnam: A technical, economic, and sensitivity analysis

Abstract

This paper explores the feasibility of deploying Carbon Capture and Storage (CCS) in X Field, located in Vietnam's Cuu Long Basin. Geological analysis reveals that Miocene sandstone formations with high porosity and secure shale caprock make X Field ideal for storing up to 39 million tonnes of CO2. Integrating CCS with Enhanced Oil Recovery (EOR) boosts economic viability by generating significant revenue from increased oil production, enhancing both financial returns and energy security.The project's success depends on effectively managing key factors like oil prices, CO2 capture costs, and storage efficiency. Strong regulatory frameworks and active public engagement are also essential. CCS in X Field presents a strategic opportunity for Vietnam to achieve its climate targets while driving economic growth and ensuring energy stability.
