2 Bow Spring Centralizers 1 Piece Slip-on 1 Piece slip-on design Made to gauge hole size Extremely robust Tolerant to under gauge hole conditions flexible Zero weak points Double curvature bow Increase flow-by-area High restoring force Designed to compress virtually flat to casing ZERO starting and running force API 10D Rated Critical casing/liner runs ECD sensitive wellbores Recommended for use in deviated wellbores, ERD liner/casings and tortuous well paths 5

3 Bow Spring Centralizers Hinged, Welded & Non-weld Heat treated centralizer bows welded directly to Centralizer end ring End ring hinged together Various product types and size combinations Turbulator fins available Usually high restoring force, generated by the centralizer bow compressed into the casing or wellbore. This also provides Increased starting and running force expected API 10D Rated Cost sensitive wells Ran over casing coupling Recommended for use in vertical and slight well bore angles 6

4 Rigid Centralizer - Positive Bar Spiralizer Slip-on Welded Positive Spiralizer has formed positive bar blades welded directly onto the centralizer end bands or Slip-on Heavy Duty Positive Spiralizer is a solid one piece unit with blades welding to the body. Provides positive casing stand-off Spiral blades assist to break linear flow whilst displacing cementing fluids, aiding cement placement Not governed by API Used in all types of well designs Most suited for horizontal and directional well designs Recommended to be run between slip on set screw stop collar(s) or coupling Recommend running all rigids between stop collars to allow centralizer to function as a bearing and to reduce torque 7

5 Rigid Centralizer Slip-on, Composite Style Spiral Blade Manufactured from Thermoplastic Polymer Reduced Torque and Drag when running in hole Thermoplastic material provides lower friction factors Provides positive casing stand-off Spiral blades assist to break linear flow while displacing cementing fluids, aiding cement placement Not governed by API Recommended for use in deviated wellbores, ERD liner/casings and tortuous well paths Horizontal and directional well designs 8

6 Rigid Centralizers Slip-on, Welded Spiral & Straight Bar With and with out set screws Straight spiral direction options Provides positive casing stand-off Not governed by API Cost sensitive wells Used in all types of well designs Most suited for horizontal and directional well designs Favorable in cased hole situations 9
