Adsorption and retention behavior of clean fracturing fluids in deep coal nanopores from a molecular perspective: Effect of rock and fluid properties

Key Points

• Adsorption of fracturing fluids in nanopores is influenced by both rock and fluid properties, enhancing performance.
• Key metrics indicate that certain fluid properties increase retention rates by up to 45% as compared to others.
• Observational analysis explores the molecular interactions between fluids and coal nanopores, revealing significant insights into retention behavior.
• Understanding these interactions may enable better fluid design strategies for enhanced coal extraction efficiency.
