Abstract	The collapse resistance of casing is influenced by many factors, among which the level of residual stresses is an essential one. This paper presents the results of research activities aimed to determine such stress level in seamless tube specimens made of grade N80 steel. These activities included: the selection – based on experimental and theoretical studies – of the most adequate method to determine the residual circumferential stresses in tubes for well casing; a series of experimental tests to define the level of such residual stresses and its variation across the tube thickness; finally, an evaluation of the influence of such stresses upon the value of the collapse pressure of casing.
