The Snapset II Packer is a compression
set tool requiring only straight set down
weight to pack-off. This packer is run
above another compression set packer
(such as the AS-III Packer) to selectively
treat, produce or inject in multiple zone
completions. This packer is also used to
isolate casing hole perforations.
This packer features a large by-pass
area to prevent swabbing when running
and retrieving. Once the packer is set,
pressure from above or below acts down
on the valve to maintain the seal and
prevent upward movement of the tubing. When releasing, the valve allows debris
to be washed from the upper slips. This
packer is equipped with an internal latch
to prevent setting prematurely when
running in the hole. When releasing,
the latch re-engages to allow movement
downhole.
