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.
