摘要

A method of installing a liner in a drilled bore below a section of bore previously lined with casing comprises the steps of: running a length of lin er into the bore such that at least an upper end of the liner is positioned in overlapping relation with at least a lower end of the casing; and plasticall y deforming a portion of the liner such that an external face of the portion forms an interference fit with an internal face of a portion of the casing. The interference fit preferably provides both hanging support for the liner and a fluid-tight seal between the liner and casing.
