Remedial Cementing Packer (RCP)

IPI's retrievable Remedial Cementing Packer (RCP) is a field proven innovative inflatable

packer system designed for retrievability after remedial cementing. The retrievable RCP

features drillable residual components, which makes it the optimal solution for shutting-off

lost-circulation zones encountered during drilling operations.

The RCP is conveyed on workstring and allows circulation during deployment. The RCP

setting sequence starts by dropping and pressuring up against a phenolic ball. Once the RCP

is fully inflated, an over-pressure is applied, shearing out the setting ball and a drillable ball

seat sleeve, which can be captured in a tailpipe ball catcher. Once the RCP system is fully set,

remedial cementing operations can commence. After the remedial cement is set, the RCP can

be deflated by applying over-pull, which shears its release pins to enable RCP packer deflation.

Once deflated, further over-pull is required to break any remaining cement bond to the packer

assembly. A drillable plastic shroud located at the bottom of the packer element is the contact

point between the RCP body and the remedial cement. The RCP packer element plastic shroud

is designed to shear off if the RCP is cemented in place, minimizing risk of becoming stuck at

setting depth.
