OFH is an industry standard, fully hydrostatic, hydraulic set and shear release single string retrievable packer. The packer is hydraulically activated by applying tubing pressure against a underneath plugging device. The packer requires only straight pull to release.
Features/Benefits:
- Operationally simple.
- Hydraulically activated, hydrostatic set-low pressure, rig pump capable activation.
- Field adjustable shear release.
- Built-in un-loader and bypass to aid in releasing and retrieving.
- Pack-off is mechanically locked constantly reinforced by hydrostatic pressure.
Triple seal multiple duro meter elements ensure pressure integrity over a wide range of temperatures and conform easily to casing irregularities.
- No mandrel movement during setting allows stacked packer application.
- Hydraulic set for low hydrostatic head wells.
- Straight pull or optional rotational release.
- Hydraulic hold-down for differential pressure from below.
Application:
- Production, injection and zonal isolation.
- Single string selective completions or dual string completions with multiple packers.
- Deviated wells or other application where no rotation for installation or removal is desired.
- Application where displacing and setting after the well is flanged up is desirable.
- Test the tubing string before packer setting or to independently set and test individual packer in multiple packer completion.
- Hydraulic hold-down buttons actuated by differential pressure from below & provide Double-Grip mechanism
