Pressure testing barriers in P&A applications is a vital element to ensure integrity in the final stage of the well lifecycle.
The CX-SVE is a robust and fully drillable cement retainer run on drill pipe and set using Coretrax’s mechanical setting tool. The device incorporates a sliding valve mechanism which allows circulation through the cement retainer when the mechanical setting tool is stung in.
This tool is ideally suited to several applications including squeeze cementing and providing a pressure-tested barrier for P&A applications. It can also be used to assist with the restoration of annular cement.
The mechanical setting tool has a snap latch stinger which creates a seal with the sliding valve of the cement retainer. This is used to function the sliding valve within the CX-SVE whilst maintaining a pressure seal between the stinger and plug.
