The hydraulic open hole packer is a completion element of the intervention tools, which provides the interval isolation for the hydraulic fracturing operation and production after reservoir stimulation. The hydraulic open hole packer can be installed into the production string. It is widely used in the horizontal well profiles. The hydraulic open hole packer provides the mechanical isolation between tubular and formation annulus with a high dierential pressure by compressing the packer elements. This packer type excludes the delay during its installation, and has a mechanism preventing unintended packer activation.
