The large flow area past the Progressive Quarter- Turn Anchor (PQA) makes it ideal for use with the Progressive Chemical Injection Sub (CIS) in applications where chemical needs to be injected below the anchor via a capillary line banded to the outside of the tubing. Minimizing the movement needed to set the anchor (1⁄4 RH Turn) also minimizes the chances of damaging the capillary line experienced with traditional anchors, such as a C1 anchor, and makes the anchor easier to set in deviated or horizontal sections of the well.
