Turborunner 5-in. completion reaming tools are newly introduced. The independently-powered high-speed tool was employed by CNR International in a horizontal application offshore in the central North Sea.
The completion-compatible reaming tool is engineered to aid first time placement of the completion or liners at target depth. It’s suited for all rigs and easy to deploy, declares the manufacturer. Turborunner is also designed to reduce risk at depth, time, and costs.
The 5-in. tool is specifically designed to support smaller open hole completion placement. It combines optimized washing with a rotational reaming capability, and avoids rotation of the completion string itself. The very low operating pressure is said to be especially suited for integration with completion systems.
In the North Sea project, placement of the liner was seen to be a significant risk due to the stability of the sand shale sequences in the long open hole section. CNR International’s drilling team selected Turborunner to provide an operational advantage in the event of difficulties in running the liner. The tool was run on a 5,500-ft-long 4 1/2-in. liner into a 6-in. open hole. Upon reaching planned depth, the tool and liner were successfully cemented in place.
A 7-in. version was successfully launched last year. Full details on the Turborunner tools suite is free.
