Retrievable Packer
The retrievable packers are used for achieving temporary isolation for performing intervention activities. They are available in different differential pressure and temperature ratings, but are normally used for less severe well conditions. Retrievable packers are available with different setting mechanism like mechanical set or hydrostatic set options. Similarly, the release options could be either pull to release, cut to release etc. Retrievable packers offer flexibility and cost benefit in cases where removal is anticipated in the short term, or require repeated setting and unsetting or packer. Retrievable packers have more complex design than permanent packers due to setting and retrieving mechanism built inside the packer.
