1. Introduction
It is used to stabilize the production and control the water by adjusting the flow area to balance the production drawdown pressure and fluid production in each section and also adjusting the pressure profile of horizontal section to delay the edge and bottom water invasion.
If specialized water control screen is used with gravel pack together, better result would be achieved.

2. Features
■ The flow path is designed on the basis of reservoir properties, horizontal length  and productivity of each well.
■ Drawdown pressure profile and fluid production profile can be balanced automatically along the entire horizontal section.
■ Delay the edge and bottom water invasion and extend the well life.
■ Realize production stabilization and water control after water breakthrough. and restrict water discharge by flow channel, reducing the water cut..
■ Balanced oil production along the whole horizontal section, with less dead oil area and higher oil production and recovery.
■ Uniform acidizing can be achieved through the flow channels.
■ Combine sand control, oil production stabilization, water control and acid stimulation together, simple to operate, and cost-effective.
