The 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 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.
