New developments in drill pipe and drill stem rotary-shouldered connections are rapidly evolving and represent enabling technologies for the industry’s continued advancement of drilling deeper, longer reach and more cost-effective wells.  The advent of high torsional capacity rotary shouldered connections is shrinking drill pipe geometrical constraints and allowing the industry to run larger pipe in smaller hole sizes, reducing time from spud to completion by delivering more hydraulic horsepower to the bit and minimizing the number of drill pipe sizes required for the well.  Enhanced drill pipe products providing more torque and tension capacity, improved hydraulics and full gas-tight pressure ratings are replacing commonly used completion tubing.  These products have been successfully used in Gulf of Mexico deepwater projects requiring up to 29,000 psi internal and 25,000 psi external pressure integrity with compression, bending and temperature.  Proprietary connections developed specifically for the BHA now offer at least nine times improved fatigue performance compared to currently used BHA API connections.  Fourth generation “casing friendly” hardfacings are now available and represent the first nanotechnology products offered for the drill stem.  The increasing desire to land heavy casing strings approaching 2 MM lbf in the deepwater environment has generated tubular design challenges that have been met with “out of the box” designs including heavy wall, Slip-Proof® sections, slip-less designs and double diameter tool joints.  This discussion will present the many completion and drill pipe technologies currently available and highlight methods to capitalize on their benefits.
