Outflow Control Device

Variperm's Q-Enforcer™ is a tubing deployed flow control device (FCD) used to maximize production efficiency by improving injection characteristics. The device’s flow conditioning extends the injecting zone length, reduces openhole erosion and casing damage, while optimizing custom injection rates with a uniform injection profile.

The Q-Enforcer maximizes injection efficiencies along the well by exit flow conditioning. The device’s laminar exit flow extends the thermal reach beyond traditional injecting zones, thus reducing the number of installations required. This increases injection efficiency at the delivery point.

This device offers operational flexibility for controlling the number of exit port numbers. The Q-Enforcer comes with two-position sliding sleeve technology and can be selectively shifted opened or closed.

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