Saltel Steel ECP-C
SALTEL STEEL ECP-C
EXTERNAL CASING PACKER - CRIMPED
Saltel Steel ECP-C is based on proprietary expandable stainless steel technology. It is designed to set at low pressure and achieve zonal Isolation, any stage cementing operation or to prevent annular fluid migration in the annulus.
The steel packer expandable sleeve is expanded between the casing and the borehole by applying pressure in the casing. It conforms to the real wellbore shape. Sealing with the borehole uneven surface is achieved through a patented thin layer of bonded elastomer. Two seal length are available - 4ft and 8ft.
The packer is built onto a one-piece mandrel by crimping. This patented design keeps casing integrity and provides high sealing and anchoring of the packer ends with the base pipe. There is no welding, no machining operation on the base casing and there is no hidden internal connection. Both ends are fixed and serve as protection to the expandable sleeve while running in the well.
The packer features an expansion valve that closes permanently the expansion port once the packer is set. The valve is activated by reaching a pre-determined pressure level. The activation pressure value can be modified by replacing a shear pin that is easily accessible. The expansion valve also provides safety if the packer is expanded in front of a wash-out. The valve system is fully protected during RIH.
- Robustness during RIH, can be worked in doglegs or tight spots
- Preserve casing integrity after packer setting
- Seal effectively in oval, out of gauge or irregular borehole
- Expansion on demand (no waiting time)
- Simple setting process. Quick installation time
