Expandable liner tieback connection

A method of connecting a first tubular member to a second tubular member located in a wellbore, the second tubular member including an upper end portion which has a greater diameter than the diameter of the first tubular member, the method comprising:

• providing a receiving member comprising a tieback profile device at the upper end of the second tubular member, the tieback profile device having a greater diameter than the diameter of the first tubular and wherein the tieback profile device includes at least one recess provided at an internal bore of the device;
• lowering the first tubular member into the wellbore until the first tubular member is located at least within the bore of the upper end portion of the second tubular member;
• and
• expanding the first tubular member until the first tubular member is sealingly connected to the second tubular member by using an expandable tool to expand the first tubular member;
• wherein the expandable tool includes a pair of seals which are vertically spaced apart, wherein the seals are actuatable to form a seal between the outer surface of the tool and the inner surface of the first tubular member to define a chamber between the seals wherein the expandable tool is configured to supply a fluid to the chamber to apply pressure on the internal surface of the first tubular member such that the first tubular member expands into the or each recess to form a seal between the second tubular member and the first tubular member.
