The REBarrier packer is an elastomeric device built on a substrate that can be easily installed on your casing with set screws and then run into the well like any other casing joint. The packer activates through the swelling properties of the rubber element upon contact with the wellbore fluids. The element absorbs selected components of the wellbore fluids into the rubber matrix, which causes the outer diameter (OD) to swell and fill the annulus between the casing and the wellbore diameter. Swellable O-rings installed on the inner diameter (ID) of the REBarrier seal the annulus between the OD of the inner casing and the ID of the barrier. The swelling mechanism for the rubber O-ring and rubber element will continue to provide long-term annular debris management, even in sections where the annular area changes irregularly. The REBarrier packer’s swelling compounds were developed and tested to downhole conditions in various sizes and percentages of swell. Thousands of field runs have validated packer performance, and to ensure maximum isolation performance of the REBarrier packer after swelling, our packer experts stand ready to help you select the optimal element OD based on the respective drilled openhole ID as well as the intended casing OD, required element thickness, and length of the element.
