Arrow-set I-X Mechanical Set Packer

Arrowset I-X Mechanical Set Packer


ASI-X  Packer  is  the  most  versatile  of  the  mechanically  set  retrievable  packers  and  may  be  used  in  any  production  application.  The  ASI-X  Packer  is  suited  for  treating, testing,  or  injection  applications,  in  pumping  or  flowing  wells,  either  deep  or  shallow.    The  packer  can  be  left  in  tension  or  compression,  depending  on  well  conditions  and  the  required  application.

A large internal by-pass reduces swabbing when running and retrieving.  The by-pass closes when the packer is set and opens prior to releasing the upper slips when retrieving to allow pressure equalization.  The J-Slot design allows easy setting and releasing; 1/4 turn right-hand set, right-hand release.

The  ASI-X  Packer  is  also  available  in  an  HP  version  which  can  withstand differential  pressures  up  to  10,000  PSI.

This  feature  allows  the  packer  to  be  utilized  in  completions  where  high  pressure  treating  operations  are  performed  and  it  is  desirable  to  leave  the tool in the well for production.

Features and Benefits

  • By-pass below upper slips to wash debris when valve is opened.
  • By-pass is opened before upper slips are released.
  • Can be set with tension for shallow well applications.
  • Can be left in tension, compression or neutral.
  • 1/4 turn right-hand set, 1/4 turn right-hand release.
  • Additional J-Slot arrangements available.
  • The packer can be run with on-off tool, which enables the tubing to be disconnected and retrieved without retrieving the packer.
  • Can be ordered 7,000 PSI or 10,000 PSI differential pressure above or below.




Packer-less Completion






Where conditions permit, the lowest cost completion with a tubing string leaves the tubing hanging from the wellhead with no packer used to isolate the casing annulus. This system allows production to flow up the tubing, the annulus, or both. The tubing string provides a means for the injection of inhibitors or the circulation of kill fluids. It typically includes a tubing retrievable safety valve with cement-through capability. In addition to the tubing, a seating nipple or a profile landing nipple can be providing for a standing valve or retrievable plug. The wireline entry guide will ensure reliable retrieval of wireline tools that might run past the tubing end.

Although this completion is economical, its use is limited by fl owing conditions and concern for protection of the tubular goods. Efficiency of fl ow can be compromised, and any leaks in the tubing or casing are difficult to detect. It also adds to the difficulty in gathering bottom hole pressure survey data.
