Thus, risk of sand production increases. We consider a case study with UCS = 2450 psi, = 4000 psi. From Figure 10, we see that if the current reservoir pressure is 4000 psi, then the critical bottomhole pressure is 2020 psia. For sand production to not occur, the bottomhole pressure must be greater than 2020 psi.

Sand Control

If sand production is expected, flow velocities should be high enough to transport sand to the point where it can be separated from the produced fluids. A balance has to be found in sizing tubulars and flowlines as they are usually designed to minimise pressure rather than optimise transport velocities.
