Experimental simulation of wormhole sanding cavity pattern
The sand production prediction model that varies with the production period was designed to calculate the critical drawdown under different water-bearing saturation states (Du et al. 2009). The above sand production mechanism and prediction methods are mainly based on the rock damage criterion from the macroscopic perspective.

Rock Fractures and Fluid Flow: Practical Problems
Fractures are mechanical breaks in rocks; they originate from strains that arise from stress concentrations around flaws, heterogeneities, and physical discontinuities.They form in response to lithostatic, tectonic, and thermal stresses and high fluid pressures. They occur at a variety of scales, from microscopic to continental.

Sand production: A smart control framework for risk mitigation
As a result, most of production wells have a critical flow rate, which is below pressure frictional loss and frictional forces are not high enough to exceed the compressive strength of the formation and leads to sand production. The critical flow rate is obtained through increasing the production rate slowly till the production of sand is detected.

Review of Sand Production Prediction Models
Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold governed by factors such as consistency of the reservoir rock, stress state and the type of completion used around the well. The amount of solids can be less than a few grams per cubic meter of reservoir fluid, posing only minor problems, or a substantial amount over a …

Sand control techniques
Restricting the well's flow rate to a level that reduces sand production is a method used occasionally. The point of the procedure is to sequentially reduce or increase the flow rate until an acceptable value of sand production is achieved. The object of this technique is to attempt to establish the maximum sand-free flow rate.

But when the gas flow rate reached 3.87–8.58 L/min, pore throats were blocked by sand particles of large sizes. When all sand particles were carried away by the gas flow, no sand production occurred and the rock permeability remained unchanged. In this experiment, the critical pressure difference was 5 MPa.
