Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.
