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.
