Description
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
