Swellable and Expandable Packers

Overview Library

Simple, cost-effective zonal isolation

ResPack swellable bonded-to-pipe and ResPack Slip swellable slip-on packers consist of an elastomer that swells on contact with wellbore fluids (water or oil). Saltel expandable steel packers expand between the casing and the borehole when pressure is applied in the casing. In all cases, the expansion seals the annulus around the pipe in open or cased holes. With no moving parts, these packers provide a simple, one-trip solution for effective zonal isolation, saving you rig time and costs.

A wide range of applications 

Schlumberger swellable and expandable packers are available for a wide range of applications, from well construction to well completion. Our packers are engineered from complex polymers or expandable steel that are suitable for high-pressure applications, such as multistage fracturing, and also for sealing in flowing wells, such as when inflow control devices (ICDs) are used. At the same time, the polymers and steel are pliant enough to accommodate washouts and irregular wellbores.

Stringent qualification at downhole conditions

Our packers undergo full-scale highly accelerated lifecycle testing and are qualified to rigorous standards. Elastomers are tested in high concentrations of hydrogen sulfide (H2S), hydrochloric acid (HCl), and carbon dioxide (CO2) at simulated downhole temperatures and pressures.

Packers are available in sizes ranging from 2 3/8 in to 13 3/8 in, for operating temperatures from 100 degF [37 degC] to 365 degF [185 degC], and with differential pressure ratings up to 15,000 psi [103 MPa].

Differential-Pressure Rating of ResPack Swellable Bonded-to-Pipe Packers

The differential-pressure rating of oil-swellable ResPack packers is a function of the swell time and the element length. The differential-pressure rating of water (brine)-swellable ResPack packers is a function of the swell time and the element length.
