Description
The GeoGLIDERTM XTREME centralizer is a low-friction centralizer irrespective of the material it is made of. It can be manufactured out of aluminum or zinc alloy, steel, or composite.
Metal variants are made by casting and can be coated with PTFE to further reduce initial frictional losses during deployment.
The composite is injection molded and further coated with PTFE and coupled with the much-reduced contact area and offset touch points, the result is exceptionally low frictional losses in the wellbore.
Features
- Offset touch contact points
- Smaller hydraulic diameter
- Smaller cross-sectional area
- Stand-off uncompromised - Total contact area < 5 in
- Less than 20% of the contact area of the industry
- standard centralizers
- Lower area susceptible to surface roughness
- No sharp edges on blades or leading edge
Advantages
- Easier to work through tight spots or borehole restrictions
- Lower ECDs when displacing fluids
- Much lower frictional losses.
- Friction factors as low as 0.05 have been achieved consistently in the field in the open hole with proper string design
- Average friction factor of +/- 0.15 is normal with a maximum of +/-0.2 seen in strings with poor centralization. - Available in sizes up to 20" casing on request.
