What is a Packer?

Packers are devices that can be placed at a desired position within a well and then be expanded indiameter to seal off the well bore or casing string at that point. Some are designed to allow passage of smaller diameter production tubing through them such as production packer.

Tube griper packer

Tubing is run into the well (smaller diameter compared to production casing and removable) to serve as a way for oil or gas to flow to the surface.

Packer is attached to it just near the bottom.

Packer is placed at a depth just above the producing interval.

When the packer is expanded, it grips the wall of the production casing and forms a seal between outside of tubing and inside of casing

swellable packer It is located at bottom of the tubing in down of the wellbore or in the production zone . .

Selective production management in horizontal wellbores

Reliably control inflow or injection within selected sections of the wellbore

Wide range of open hole isolation

Why it Will?

Instant setting and sealing capabilities

High differential pressure ratings

Long term isolation reliability

Where it work1-Horizontal and vertical wells Open hole zonal isolation Selective production

2-Deepwater Gas or water shutoff Stimulation / fracturing

3-Mature fields Re-frac opportunities

Production packer production packer run integral to the production tubing to provide reservoir isolation in the casing annulus and production tubing anchoring capabilities.

Set using hydrostatic wellbore pressure and applied surface pressure without plugs

Packer design allows for the largest ID capable in a retrievable packer and is used extensively in deep water applications with a field-proven reliability track record
