Abstract
An expandable tubing (12) for a well bore hole (14) in which selected length portions (24, 26, 28) are weakened by a slot configuration (FIGS. 2, 3, 4) to obtain predetermined expansion characteristics. The slot configurations are tailored or selected for a predetermined bore hole length and may be expanded to different radial diameters to conform generally to the peripheral contour of the bore hole. Tubing portions (29) between the slotted length potions (24, 26, 28) are unweakened.
