ICD Screen

The ICD (Inflow Control Device) screen is designed to balance the producing profiles and delay the water influx of horizontal wells by regulating flow entrance through orifices.

The device includes a nozzle joint with a MGC (Multi-Grade Combined) screen joint, various amount (2-8) of nozzles could be installed onto one joint according to the completion design. The nozzles are made of tungsten-cobalt alloy with high anti­abrasion capacity, the diameters of nozzles ranges from 1.6mm to 5.0mm, enabling a wide range of pressure drop design.

The MGC screen is designed to provide maximum anti-plugging performance, according to the sand control requirements, it could be replaced with premium screens or other types of screens.

The whole screen device contains no moving parts and is robust enough for long term service.

Features

● High strength tungsten-cobalt alloy nozzle

● Screen made of 316L steel

● Various nozzle diameters and amount per joint available

Benefits

● Maximum robustness with anti-abrasion nozzles and high strength screens

● Reliable inflow control performance

Applications

Sand control and inflow control in horizontal wells

Pressure and Flow Data

A large number of tests were carried out on the change of ICD screen pressure with flow rate using the flow resistance test device, and the test medium included water and white oil, and the test results are as follows. ICD faucets produce similar pressure drops to oil and water, with slightly less resistance to oil than water, and the smaller the faucet, the smaller the difference in flow limits. Tests can be customized according to the site conditions to determine a more accurate ICD completion design.
