can be coiled or jointed tubing the string 18 can also have either a round or folded cross section in fig2 the pressure has been applied as indicated by arrow 28 to move the string 18 in a downward direction such movement acts to enlarge the swages to their desired diameters for expansion the upper end 30 is not yet expanded leaving a gap 32 for fluid displacement when cementing begins as depicted in fig3 in fig3 the string 16 is tagged into a cement shoe that is not shown and cement is delivered into the annulus 34 at the conclusion of cementing in fig4 the string 16 is released from the shoe not shown and the swages 24 and 26 are raised in a manner that only swage 24 is deployed the cement in the unexpanded annulus 32 will remain in place until squeezed out of the liner top during liner lap expansion the swage 24 is either pulled by string 16 or is driven up by pressure delivered through string 16 to below swage 26 to drive the swages 24 and 26 out through the string 18 to close the gap 32 as shown in fig5 fig6 shows the expansion assembly removed and the resulting wellbore completed as a monobore with the.
