Operating Principle

A downhole flow-control valve can be configured to control or redirect fluid flow within the tool string. In one common intervention design, normal circulation can flow through the coiled tubing/tool string, while increasing flow rate causes the valve to divert flow through a secondary flow path at a predetermined pressure. Reducing the flow rate allows the tool-string pressure to bleed down.

This type of arrangement can be used to:

Control circulation during intervention

Apply pressure to downstream tools

Protect BHA components from premature activation

Control fluid delivery to downhole tools

Support inflatable-element BHA operations

Key Features

High reliability

Downhole flow regulation

Pressure/flow-responsive operation

Robust high-strength construction

High-pressure wellbore capability

Configurable connection sizes

H₂S-service configurations available where specified

Replaceable/redressable components on applicable designs

Remote-operation options

Suitable for demanding well-intervention environments

Commercial downhole flow-control valves are available in different outside diameters, operating pressures, flow areas and thread configurations. For example, one established intervention design offers 1.688", 2.125" and 2.875" OD configurations with pressure settings up to 2,000 psi. These figures are reference examples, not specifications for the Driscoil-listed unit.
