Simulation of Sand Production in Unconsolidated Heavy

The production of sand may lead to the change of formation flow-related parameters such as permeability, porosity and mechanical parameters such as cohesion, and it also causes near wellbore stress redistribution. Thus, sand production is a very complicated process involving both fluid flow and geomechanical problems.

Sand Production Caused by Foamy Oil Flow SpringerLink

Fluid pressure in the foamy zone exhibits a steeper gradient, compared to the nonfoamy flow. The conditions of sand production instability via tensile failure at the foamy front are also determined, and this constitutes a condition for liquefaction and loss of effective stress in the granular medium.

Sediment Heterogeneity and Sand Production in Gas

Sand production in reservoirs at shallow depths and low confining stresses (less than 10 MPa) are likely to be influenced by fluid flow effects like those described by the Shields (1936) diagram. The relative density of the formation may also affect the nature of the sand production in these reservoirs.
