The WellEnTech Mechanical Bow Spring Centraliser is assembled as part of a Coiled Tubing BHA. It is fitted to the BHA in the desired position and run in hole. Because it is a mechanical tool, there is no flow required to enable it to operate. The leaf springs provide centralisation as soon as the BHA enters the well bore. To redress, the bottom sub is backed off and the springs along with the spring supports can be removed.
