Inflow control device in openhole horizontal well

An Inflow-control device (ICD) is a permanent completion hardware that is installed as part of well completions which often known as an equalizer or choking device. It offers numbers of unique benefits especially in the horizontal application, but it is not adjustable or non-retrievable hardware. Fr...
