Total Control NonStop Driller
The Total Control Non Stop Driller is a sub-based constant circulation system which enables the continuous circulation of drill fluids downhole while making or breaking drill pipe connections.
The system has been designed to address operator concerns including drilling efficiency, operational safety, hole condition and equipment integration.
With Canrig’s NSD system, continuous circulation and true constant bottom hole pressure while making connections is a reality. This improves wellbore stability and hole cleaning, reduces the risk of kicks, and optimizes drilling performance.
