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.

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.
APPLICATIONS:
■
Shut-off lost-circulation zones without running and cementing casing
Test, squeeze and treat operations
Vertical, inclined and horizontal wells
Workover/Well intervention with a Retrievable Inflatable Bridge Plug (RIBP) as a pair
■
■
■
■
FEATURES:
■ Stand-alone retrievable treatment while drilling to eliminate the need for a drillable or
permanent system
Conveyed on workstring
Allows circulation during deployment
Optional short fiberglass pipe stinger below the packer as an easily drillable tailpipe
Optional tailpipe ball catcher
Optional shearable plastic shroud located at the bottom of the RCP packer element,
minimizing the risk of tool becoming stuck at setting depth
