SwellPLUS Packer

Swellable Zonal Isolation

The Packers Plus SwellPLUS™ packers provide an economical solution for achieving annular isolation in multi-stage completion systems. The elastomer element is specially designed to maintain a high pressure rating during stimulation and throughout the life of the well. This innovative, field-proven packer allows for effective zonal isolation regardless of well geometry. During setting operations, activation fluid is absorbed into the SwellPLUS packer over a period of time by diffusion, enabling the packer to swell and seal against the wellbore.

Because Packers Plus multi-stage completion systems are modular with regard to tool placement, SwellPLUS packers can be combined with a variety of Packers Plus tools and systems, enabling customized design for targeted delivery of the stimulation program.

The SwellPLUS packer offers many features and benefits:

–Single element
–Element bonded to mandrel
–No moving parts
–Ease of installation
–Application-specific elastomers
–Mandrel material can match completion tool string material
–Can accommodate a wide range of end connection
–Seals in irregular wellbore geometries
–Anti-extrusion rings hold element in place
Designed to withstand:
– Varying temperatures
– Temperature cycling during stimulation

The SwellPLUS packer can be used in many applications:

–Open and cased hole horizontal and vertical wells
–Multi-stage stimulation

SwellPLUS Packer

The SwellPLUS packer has no moving parts and the elastomer element expands upon contact with activation fluid, sealing against the wellbore. The time required for the packer to swell and hold the required pressure is determined by the downhole conditions, activation fluid composition and the element design. The specially designed elastomer element is capable of withstanding varying temperatures that ensures reliable zonal isolation during stimulation operations and throughout the life of the well.

Acid Isolation Sub-Assembly

The SwellPLUS Acid Isolation Sub-Assembly consists of two SwellPLUS packers and a single RockSEAL® H2 packer that is hydraulically set. The SwellPLUS Acid Isolation Sub-Assembly is specially designed to provide annular isolation in multi-stage completion systems, during stimulation and throughout the life of the well. The sub-assembly combines innovative elastomers from two different packer models to provide reliable high-pressure zonal isolation in the most challenging wellbore conditions.

See how the SwellPLUS packer works


The SwellPLUS packer is assembled in the completion tool string, according to the well requirements, and run into the wellbore to the
planned depth.


Activation fluid is absorbed into the SwellPLUS packer over a period of time by diffusion, enabling the packer to swell and seal against the wellbore.


Once the SwellPLUS packers are set the stimulation program can begin.

 Our commitment to quality

Packers Plus successful stimulation services begin with a fully integrated quality assurance and quality control (QA/QC) process that begins at the design stage and follows each tool through manufacturing, assembly, testing, shipping and installation. Automation and robotics are incorporated into our proven process to ensure consistency and repeatability of key criteria in each step as we design, develop and manufacture our patented tools and systems. As a commitment to quality and meeting stringent standards, Packers Plus has achieved ISO 9001 certification and  API Q1 Certification for our manufacturing and engineering operations in Edmonton, AB, and ISO 9001 in Houston, TX.
