Review of characterization methods for shale wettability: advances, applications, and future perspectives
Xiaomei Zhou
Wettability significantly controls fluid distribution and mobility in shale reservoirs. Accurate characterization enables better reservoir management and improves shale oil recovery. This review systematically summarizes wettability characterization methods across four sample scales: core thin sections, core plugs, crushed rock samples, and digital cores. It aims to compare their advantages, limitations, and practical applicability. We analyze established techniques such as contact angle measure
