From its founding in 1960, Grant Prideco has become the world's technology leader for drill pipe and drill stem accessories. ... Whether manufacturing products for the simplest well or for drilling in the harshest environments, it is our mission to increase efficiency through improved performance to reduce lifted cost per barrel. From the design room to the wellsite, we produce the industry’s most innovative drill stem technologies to help you achieve lasting success. Our offerings include a full range of proprietary and API rotary shouldered connections for drill pipe, drill collars, heavy weight drill pipe, and other drill stem components. We combine an integrated supply chain, worldwide operations, expert engineering and design resources coupled with a global network of Licensees to repair connection and build accessories, to meet your operational needs. Connection Technologies A wide portfolio of connections allows you to select the best suited solution for your particular drilling needs. Optimize the balance between performance (torque, hydraulics, tensile capacity) and total cost of ownership. With four generations of double-shouldered connections, we have developed technologies to meet the demands of every drilling challenge. Grade Technologies The development of proprietary materials specific to industry needs means we have developed purpose engineered drill pipe resulting in improved product performance and integrity. Our high-strength grades are particularly for Landing Strings and pipe for deep drilling, which require high tensile capacity. Our sour service grades optimize performance in the balance between sulfide stress cracking (SSC) resistance and product performance (torque/tension/hydraulics). Custom Engineered Products In addition to a complete line of drill stem products and accessories, we design, engineer, qualify, and produce solutions for specialized and unusually demanding field operations. read more
