`V Production Inflatable - BULLDOG“VI HD Inflate
`
`
`
`BULLDOG HD inflatable packers are a tough new breed of inflatable
`packers that provide reliable, consistent isolation protection and
`security, even under the extreme forces of fracing a well.
`
`Features/Benefits
`
`
`
`- The discontinuous-rib element provides superior openhole
`isolation by expanding up to 3.5 times its original diameter to
`conform to borehole irregularities and provide total contact with
`the formation.
`
`' The protective seal shield prevents premature element expansion
`during run-in.

`V Swellable Packer — What Is It?
`
`
`
`- A rubber that swells when immersed in well fluids (water, hydrocarbon, or
`mixture of both)
`
`' Rubber volume increases proportionally as liquid diffuses into rubber
`
`° Swell time and volume can be controlled
`
`Benefits of swellables
`
`— Will swell into over-sized or odd shape holes
`
`— As long as there is activation fluid, it will continue to re-seal
`— There are no mechanical parts
`— Simply place in the string where needed
`
`— Saves money on personnel

`Step #2 - Applied differential pressure at the packer unlocks the setting piston allowing the
`compression element to set. Force from the piston is applied to the compression element through a
`thin sleeve under the top swellable element.
`Step #3 - Compression element is set.
`Step #4 - Swellable element packs off against the wellbore using the well fluids to activate the

`packers.

`Substantially reduces the operational time normally

`
`A composite skin covers the ports to keep free of cement.
`
`A garage is used to reduce the possibility of sand in the
`HWB shifting tool
`
`
`
`Once the liner hanger is set, the cement is pumped
`through the tubing out the shoe. The wiper plugs
`used during cementing will not open the sleeves
`since all sleeves move down to close. Two hydraulic
`Weatherford (HWB) shifting tools are utilized to
`selectively open and close the sleeves before and
`after the fractures.
