Liner. Liner is a casing string that does not extend back to the wellhead but instead is hung from another casing string. Liners are used instead of full casing strings to reduce cost, improve hydraulic performance when drilling deeper, allow the use of larger tubing above the liner top, and not represent a tension limitation for a rig.

A liner is a short string of casing that does not reach the surface. The liner is hung from the bottom of the previous casing string using a liner hanger that grips the bottom of the previous casing with a set of slips. Figure 4.17.18 shows typical liner types. The liner is run into the borehole on the drillpipe and the cementing operation for the liner is carried out through the same drillpipe.
