Reservoir-scale modeling and techno-economic analysis of in-situ hydrogen production from heavy oil reservoirs via cyclic air-steam injection

Key Points

• In-situ hydrogen production is feasible under specific conditions, leading to significant economic benefits.
• The analysis shows a potential cost reduction of up to 20% using cyclic air-steam injection methods.
• Reservoir-scale modeling assessed the interaction of heavy oil and injected gases, yielding promising output levels.
• Highlights the need for more comprehensive studies to validate the techno-economic benefits in real-world settings.
