<strong>Weatherford</strong>’s UltraPak U HPHT 15K production packer is a highperformance,<br />
permanent packer for environments with high differential<br />
pressures and temperatures up to 450°F (232°C). The packer can be set<br />
on wireline or with a hydraulic setting tool. The Aflas ® packing element<br />
system (patent pending) provides 360° casing contact to prevent element<br />
extrusion at high temperatures and pressures. The packer has passed<br />
rigorous ISO 14310 testing and is designed to withstand 15,000 psi (103<br />
MPa) of differential pressure above or below.<br />
Designed for stimulation jobs in high-pressure and high-temperature<br />
zones, the packer can also be used later to produce a zone by removing<br />
the plug with the production string and landing the seals. The packer can<br />
be converted to a bridge plug by setting a wireline plug in a profile nipple<br />
below the packer. The conversion enables the removal of the tubing string<br />
without killing the well. The lower zone can be produced later by removing<br />
the plug from the profile nipple.<br />
Applications<br />
• Stimulations in high-pressure and high-temperature zones<br />
• Lower-zone isolation, using the packer as a bridge plug<br />
Features, Advantages and Benefits<br />
• The packer is tested to ISO 14310 standards to deliver consistent<br />
performance within the API minimum and maximum casing weight<br />
parameters.<br />
• The packer has been tested in Q125 collapse-resistant casing to<br />
eliminate the need for carbide insert slips and reduce cost.<br />
• The upper-scoop head design enables the easy stabbing of seals into the<br />
packer in deviated wellbores, simplifying installation and saving valuable<br />
rig time and costs.<br />
• The patent-pending Aflas packing element system prevents rubber<br />
extrusion at high temperatures and pressures, which provides sealing<br />
reliability under extreme conditions.<br />
• One-piece slips prevent premature setting of the packer.<br />
• Ductile cast-iron full-strength, full-circle slips distribute the load evenly<br />
around the parent casing wall, maximizing the load rating and reliability.<br />
