The PSD plays a critical role in screen plugging. Fine-grained sand tends to clog the screen first (Underdown and Hopkins 2008). Larger particles are retained on the screen, while finer particles pass through the openings, as the fine sand is smaller than the weave void size (Wu et al. 2016b). Therefore, solid retention on a screen increases ...
