Outflow Control Device

Variperm’s Q-Distributor™ is used for optimal steam injection distribution control. Multiple device deployment on a single injection string can enhance the distribution with specific injection placements. Wellbore modelling software can be used to optimize placement and rates. The Q-Distributor is tubing deployed and can be customized for flow and pressure drop requirements in terms of two-position (2P) sleeve option with multiple ports. The Q-Distributor can be opened or closed in one trip via coiled tubing.
