Inflow and Outflow Control Device
Q-SelectorVariperm’s Q-Selector is a liner deployed flow control device (FCD) for new well completions with a simple inner port tube and an outer screen. The Q-Selector can improve the distribution into the target formation and control the inflow of produced fluids.

For injection, the Q-Selector provides choked flow and can be designed to allow for higher injection pressures, which may provide strategic fracturing of the reservoir sand for specific exploitation applications. For production, oil is preferentially produced over steam, water, and gas. Each Q-Selector is completed and custom designed with Variperm’s screen technologies, resulting in large openflow areas for optimal exposure to the reservoir. 

The Q-Selector is manufactured in an API Q1™ Certified facility.
