The paper addresses these running and handling issues and provides guidelines to mitigate these problems. Excessive tool joint and drillpipe body wear have also been...

... applications, but it also has some disadvantages. It has relatively low yield strength of approximately 69,000 psi (highest yield strength alloy used for drill pipe). Consequently, it has a lower strength to weight ratio in air than ultra-high strength steel drill pipe when factoring in the steel tool joints...

The system is virtually transparent to standard rig procedures and offers robust, reliable operation. The new system has successfully demonstrated...
