Abstract:
1. A method of lining a wellbore, comprising: placing a first liner in the wellbore, the first liner having a lower section; placing a second liner in the wellbore, with an upper section of the second liner placed inside the lower section of the first liner; positioning an upper sealing member and a lower sealing member in the wellbore to form a pressure chamber, wherein the upper sealing member and the lower sealing member move axially away from one another, the axial movement causing the work string to move upward and pull the expander through a bore of the second liner; expanding the second liner using the pressure chamber; and positioning the upper and the lower sealing members in the first liner and above the second liner, thereby hydraulically isolating an inner bore of the second liner from the pressure chamber.
