SIMULATION OF SAND PARTICLE FLOW THROUGH SAND SCREEN IN OIL WELL

Sand production is a process occurs in oil and gas wells during the process of
drilling recovery hole. The sandstone being drilled is left unsupported next to the
cavity and dislodged sand grains can enter the oil recovery system. Sand production
can cause several problems such as clogging up of the well or damage the wall
equipment. Thus, the study of sand production is very important for safe and
economical oil and gas production. Most of numerical models to predict the behaviour
of sand in the well that have been used until now are continuum-based, but this
approach cannot easily capture the important properties or features of the sand
production problem and it is a difficult task due to the large number of interactions and
non-linearities intrinsic to the problem.
