Ensures zonal isolation during hydraulic fracturing.
Eliminates intentional setting by applying of overpull or by slacking-off.
Setting options: production string or open hole, it offers broad range of applications in horizontal wells.
Can also be used as a packer for collar cementing in protected configuration (after setting the activation pressure to the required value).
Non-extrusion system increases rated ID range of the open hole where the packer provides zonal isolation with max. acceptable differential pressure.
