ABSTRACT:
The present invention utilizes a centralizer having a plurality of segmented stress risers. The segmented stress risers are designed to allow sufficient strength to maintain the tubing in a centralized downhole location, while to allow for the stress relief grooves to be sheared off when a wash pipe or similar device is utilized to clean out any unwanted build up of material or deposits in the borehole. Once the segments have been sheared off they can be circulated out of borehole.
