Dynamic inflow control valve

Inflow control in horizontal oil wells under the conditions of changing the character of the zonal fluid inflow makes great impact on oil productivity. The manageable filter is a modification of the downhole filter, allowing the inflow regime to be switched by means of a special sliding sleeve.

AlphaPort allows operators to dynamically manage inflow profile along horizontal wells and achieve optimal well performance from reservoir intervals. The special valve can be switched for open or close position to do operations for inflow control for optimization pressure profile along the well.

AlfaPort is two-position valve specially designed for different applications to control inflow profile. The device can be equipped with special nozzles for inflow control.

AlfaPort can be integrated with different sand screens systems like wire wrapped screens.  We get complete solution in the combination of port and screen.

Operational solutions for switching AlfaPort devices can be accepted based on PLT data or chemical tracer technology monitoring data.
