ABSTRACT:
A liner (L) includes a well tool, or liner portion (LP) which may be connected anywhere in the longitudinal extent of the liner (L) that is overlapped by a well bore tubular member. The well tool includes a liner hanger (LH) and packer (P) thereon which are releasable sequentially by manipulating the liner (L), or liner portion (LP) to secure the liner hanger (LH) with the well bore tubular member (C) without actuating the packer (P) until it is desired to do so, even though weight may be applied to the packer (P) during the above operations. The packer is set and secured below the cement which is above the packer by manipulating the liner.
