Drilling ultra-deep wells places significant requirements on the drillstring. Lengthy drillstrings lead to high tensile loads, which lead to slip-crushing, hoisting issues and drill pipe collapse capacity concerns at the [...]

Field use onshore and offshore has proven performance of relatively new 5 7/8-in. drill pipe in challenging wells. Design factors are overviewed for the drill pipe and important new deepwater [...]

ARCO Exploration and Production Technology has pioneered the use of probabilistic oil country tubular goods (OCTG) for at least eight years. Its experience has highlighted the project specifications that would benefit from this approach. OCTG is basically dependent on the preciseness of the measurement and interpretation of material and dimensional properties of collapse- and burst-driven tubulars. The availability of detailed pipe performance properties and field loads makes possible a cost-efficient and integrated methodology., Casing failure causes, focusing on operational problems and examples of successful applications, highlight need for different approach and potential benefits of non-conventional tubular design technology Probabilistic oil country tubular goods [...]
