Cementing ProductsSpiraGlider ™ Centralizer System Weatherford’s SpiraGlider centralizer allows for optimal mud displacement for vertical, inclined, and horizontal wells. The system consists of a steel centralizer and two asymmetrically beveled stop collars shaped to minimize running resistance. Special rounded blades reduce casing sliding friction while the stop collar performs as a positioning device. The stop collar also serves as a protection tool, producing a ramp (rather than a square shoulder) so that the centralizer can climb over restrictions in the wellbore. The SpiraGlider centralizer is available in heavy-duty (HD) or single-collar (SC) configurations with straight or spiral blades, and can be used along with standard centralizers or centralizer subs. The SpiraGlider HD system is recommended when extremely high axial loads are anticipated. The SpiraGlider SC for horizontal wells uses a single collar. Applications • Vertical, inclined, and horizontal wells • Extended-reach wells and wells with high dogleg severity Features, Advantages and Benefits • The steel centralizer’s design provides a bearing surface for lower drag forces, which requires less rotational torque than conventional centralizers, enhancing rotation and running efficiency. • Both spiral- and straight-blade configurations capitalize on the “sled effect” to minimize drag forces while running pipe. The blades glide smoothly on the low side of the borehole wall. Wide symmetrical fins, beveled smooth at both ends, glide easily over restrictions. weatherford.com 1 • The robust steel design—combined with modern manufacturing methods, including mechanical forming and robotic welding—makes this centralizer suitable for the most demanding well conditions, enabling its use in any well. • The hydrodynamic shape of the system’s spiral blades allows optimal mud displacement during the cementing process, minimizing pressure drop and local turbulences across the centralizer. © 2008­–2013 Weatherford.
