Everybody knows that horizontal wells can increase the effective drainage area and thus increase the oil recovery factor (ORF). But the operation of horizontal wells with open trunk without the use of filter-casing packers may lead to sand, gas and water seepage. Which in turn will entail reductions in oil production at an early stage? To equalize the fluid flow is widely used device of the same name - an inflow control device (ICD), along with filters and behind-packers. This system allows you to increase the duration of the well with minimal water cut and gas breakthrough. But along with the ICD has modern device inflow control in horizontal wells developed by Russian companies.
