Swellable Packer

Mechanical packers have been used in non-cemented completions to create an annular seal between the open hole and the production casing for many years.

But in some cases such as slotted liners, it is not possible to pressure up and set the packers. This creates an opportunity for introducing Swellable Packers.


Description

Description

The swell packer system can be used either in cased or openhole wells. In some openhole applications, operator may be able to avoid cementing and perforating altogether, reducing the expense associated with these operations. By reducing well construction costs, saving rig time, and isolating producing zones, the Swell packer system attain previously unachievable levels of oilfield performance.


Depending on the characteristic of the natural rubber, it swells when exposed to hydrocarbon / water based fluid, the amount of swell depends on the chemistry of  the fluid and the temperature at which the exposure occurs. Fluid absorption into the swellable elastomer occurs through diffusion. It diffuses into the elastomer through the random thermal motion of the atoms that are in the fluid.
