The system of claim 54, wherein one of the discrete portions of the tubular liner is radially expanded by injecting a fluidic material into the tubular liner; and wherein the other discrete portions of the tubular liner are radially expanded by pulling an expansion cone through the other discrete portions of the tubular liner.
58. The system of claim 54, wherein the tubular liner comprises a plurality of tubular members; and wherein one or more of the tubular members are radially expanded into engagement with the borehole and one or more of the tubular members are not radially expanded into engagement with the borehole.
59. The system of claim 54, wherein the tubular members that are radially expanded into engagement with the borehole comprise a portion that is radially expanded into engagement with the borehole and a portion that is not radially expanded into engagement with the borehole.
60. The system of claim 54, wherein prior to the radial expansion the tubular PATENT
liner comprises:
one or more expandable tubular members that each comprise:
a tubular body comprising an intermediate portion and first and second expanded end portions coupled to opposing ends of the intermediate portion; and a sealing member coupled to the exterior surface of the intermediate portion; and one or more slotted tubular members coupled to the expandable tubular members;
wherein the inside diameters of the slotted tubular members are greater than or equal to the maximum inside diameters of the expandable tubular members.
