Open Hole Centralizer

 

The KINGWELL Open Hole Centralizer is mainly used with KINGWELL Open Hole Packers, generally as part of the KINGWELL Multi-Stage Frac System. The Centralizer helps to protect the packers from damage during equipment installation in the open hole section of the well bore as well as helping to centralize the packers during the setting procedure. The Centralizer freely swivels to allow for rotation when running in the hole if required and has spiraled grooves to ensure good circulation.
