Abstract
A method of forming a wellbore casing within a borehole that traverses a subterranean formation includes the steps of assembling a tubular liner by coupling a threaded portion of a first tubular member to a threaded portion of a second tubular member and coupling a tubular sleeve to the threaded portions of the first and second tubular members. The method further includes positioning the wellbore casing within the borehole and radially expanding and plastically deforming the wellbore casing assembly within the borehole. The step of coupling the tubular sleeve through the threaded portions of the and second tubular members includes applying impulsive magnetic energy to the tubular sleeve.
