Fluid Properties Effects on Sand Production using Discrete

sand production strongly depends on the flow rate and also the confining pressure (i.e., in-situ stresses). Kaffash and Shadizadeh [8] developed a model for SP rate prediction by coupling fluid flow, particles erosion, and mechanical defor-mation using finite difference method (FDM). Shirinabadi et al. [9] investigated the SP mecha-
