Opportunities to improve rig floor safety, reduce risks and re duce costs have motivated operators to utilize-the top, drive for casing running operations. Simple and easy approaches for applying make-up torque and hoisting loads to the casing string have been used with some success, but in some applications performing these functions safely, economically and without connection damage has not been trivial. Operational logistics, management of loads that cause casing thread damage and prevention of pipe body damage are examples of challenges requiring sound technical solution. Pipe handling logistics, including engagement of the casing grip, must be executed efficiently without damaging casing threads or scaling surfaces. Similarly, bending loads resulting from rig misalignment or casing curvature can initiate thread damage if uncertainties remain unmanaged. Finally, local cold working of pipe body material increases stress cracking susceptibility, particularly on inner surfaces, and may reduce casing string reliability. Successful use of casing running technology depends on selecting a system that meets the technical requirements of the application. A sound understanding of casing thread make-up, drilling rig operations and the interaction between the two en ables critical evaluation of emerging technologies and reduces. This paper the risk of commercial failure resents the background behind such evaluation and discusses a range of technologies in the context of that background.
