Permanent Completions<br />
UltraPak U Permanent Sealbore Packer<br />
12 © 2005-2010 <strong>Weatherford</strong>. All rights reserved.<br />
<strong>Weatherford</strong>’s UltraPak U permanent sealbore packer is a robust, highperformance,<br />
permanent packer designed for high differential pressure in<br />
single- or multiple-zone applications in straight or highly deviated wellbores.<br />
The packer features a large upper bore that permits completions with<br />
large-ID tubing in wells with high production rates. This packer can be run<br />
with tubing anchored in the upper bore or with a polished bore receptacle<br />
(PBR) above the packer for completions requiring tubing movement<br />
compensation.<br />
The UltraPak U packer has passed rigorous ISO 14310 testing and has<br />
been tested in Q125 casing. Performance-rating envelopes, developed for<br />
each size, display combination loading from pressure and axial loads.<br />
The packer is available with materials tailored for hostile environments,<br />
including premium elastomers rated up to 350°F (177°C).<br />
Applications<br />
• High-pressure production or testing<br />
• Fracture stimulation jobs with anchored or floating tubing strings<br />
• Lower-zone isolation, using the packer as a bridge plug<br />
• Upper-completion workover without the need to unseat the packer<br />
Features, Advantages and Benefits<br />
• The packer is fully envelope-tested to ISO 14310, ensuring extra security<br />
in high-risk gas wells.<br />
• The large upper bore allows completions with large-ID tubing to maximize<br />
flow rates and improve access to the reservoir by wireline tools.<br />
• The upper-scoop head design allows easy stabbing of seals into the<br />
packer in deviated wellbores, simplifying installation and saving valuable<br />
rig time and costs.<br />
• The packer has been tested in Q125 collapse-resistant casing to<br />
eliminate the need for carbide insert slips and reduce costs.<br />
• The packer is available with materials and elastomers designed for<br />
hostile environments, providing flexibility in wellbore applications.<br />
• Ductile, cast-iron, full-strength, full-circle slips distribute the load evenly<br />
around the parent casing wall, maximizing load rating and reliability.
