       50 . The method of  claim 49 , wherein a plurality of discrete portions of the tubular liner are radially expanded into engagement with the wellbore casing.  
   
   
       51 . The method of  claim 49 , wherein the remaining portions of the tubular liner are not radially expanded.  
   
   
       52 . The method of  claim 49 , wherein the discrete portions of the tubular liner are radially expanded by injecting a fluidic material into the tubular liner.  
   
   
       53 . The method of  claim 49 , wherein the tubular liner comprises a plurality of expandable tubular members, 
 wherein one or more of the expandable tubular members are radially expanded into engagement with the wellbore casing, and    wherein a plurality of the expandable tubular members are not radially expanded into engagement with the wellbore casing.    
   
   
       54 . A system for lining a wellbore casing, comprising: 
 means for positioning a tubular liner within the wellbore casing; and    means for radially expanding one or more discrete portions of the tubular liner into engagement with the wellbore casing,    wherein the tubular liner comprises one or more expandable tubular members that each comprise:    a first tubular portion, a second tubular portion, and an intermediate tubular portion coupled between the first and second tubular portions; and    a sealing member coupled to the exterior surface of the intermediate tubular portion, and    wherein the inside diameters of the first and second tubular portions are greater than the inside diameter of the intermediate tubular portion.    
   
   
       55 . The system of  claim 54 , wherein a plurality of discrete portions of the tubular liner are radially expanded into engagement with the wellbore casing.  
   
   
       56 . The system of  claim 54 , wherein the remaining portions of the tubular liner are not radially expanded.  
   
   
       57 . The system of  claim 54 , wherein the discrete portions of the tubular liner are radially expanded by injecting a fluidic material into the tubular liner.  
   
   
       58 . The system of  claim 54 , wherein the tubular liner comprises a plurality of tubular members, 
 wherein one or more of the tubular members are radially expanded into engagement with the wellbore casing, and    wherein a plurality of the tubular members are not radially expanded into engagement with the wellbore casing.    
   
   
       59 . An apparatus, comprising: 
 a subterranean formation defining a borehole;    a casing positioned in and coupled to the borehole; and    a tubular liner positioned in and coupled to the casing at one or more discrete locations,    wherein the tubular liner comprises one or more radially expanded and plastically deformed tubular members that each comprise:    a first tubular portion, a second tubular portion, and an intermediate tubular portion coupled between the first and second tubular portions; and    a sealing member coupled to the exterior surface of the intermediate tubular portion that engages the interior surface of the casing,    wherein the intermediate tubular portion is radially expanded and plastically deformed, and    wherein the first and second tubular portions are not radially expanded and plastically deformed.    
   
   
       60 . The apparatus of  claim 59 , wherein the tubular liner comprises a plurality of the radially expanded and plastically deformed tubular members.  
   
   
       61 . The apparatus of  claim 60 , wherein the tubular liner further comprises one or more other tubular members, 
 and wherein the other tubular members are interleaved among the radially expanded and plastically deformed tubular members.    
   
   
       62 . A method of lining a wellbore casing, comprising: 
 positioning a tubular liner within the wellbore casing; and    radially expanding a plurality of discrete portions of the tubular liner into engagement with the wellbore casing,    wherein the tubular liner comprises one or more expandable tubular members that each comprise:    a first tubular portion, a second tubular portion, and an intermediate tubular portion coupled between the first and second tubular portions; and    a sealing member coupled to the exterior surface of the intermediate tubular portion, and    wherein the inside diameters of the first and second tubular portions are greater than the inside diameter of the intermediate tubular portion.    
   
   
       63 . The method of  claim 62 , wherein remaining portions of the tubular liner, other than the discrete portions, are not radially expanded.  
   
   
       64 . The method of  claim 62 , wherein the discrete portions of the tubular liner are radially expanded by injecting a fluidic material into the tubular liner.  
   
   
       65 . The method of  claim 62 , wherein one or more of the expandable tubular members are radially expanded into engagement with the wellbore casing, and 
 wherein a plurality of the expandable tubular members are not radially expanded into engagement with the wellbore casing.    
   
   
       66 . The method of  claim 62 , wherein one or more of the expandable tubular members are radially expanded into engagement with the wellbore casing, and 
 wherein the tubular liner comprises one or more other tubular members that are interleaved among the expandable tubular members.    
   
   
       67 . A system for lining a wellbore casing, comprising: 
 means for positioning a tubular liner within the wellbore casing; and    means for radially expanding a plurality of discrete portions of the tubular liner into engagement with the wellbore casing,    wherein the tubular liner comprises one or more expandable tubular members that each comprise:    a first tubular portion, a second tubular portion, and an intermediate tubular portion coupled between the first and second tubular portions; and    a sealing member coupled to the exterior surface of the intermediate tubular portion, and    wherein the inside diameters of the first and second tubular portions are greater than the inside diameter of the intermediate tubular portion.

       69 . The system of  claim 67 , wherein the discrete portions of the tubular liner are radially expanded by injecting a fluidic material into the tubular liner.  
   
   
       70 . The system of  claim 67 , wherein one or more of the expandable tubular members are radially expanded into engagement with the wellbore casing, and 
 wherein a plurality of the expandable tubular members are not radially expanded into engagement with the wellbore casing.    
   
   
       71 . The system of  claim 67 , wherein one or more of the expandable tubular members are radially expanded into engagement with the wellbore casing, 
 wherein the tubular liner comprises one or more other tubular members that are interleaved among the expandable tubular members.    
   
   
       72 . An apparatus, comprising: 
 a subterranean formation defining a borehole;    a casing positioned in and coupled to the borehole; and    a tubular liner positioned in and coupled to the casing at a plurality of discrete spaced apart locations,    wherein the tubular liner comprises one or more radially expanded and plastically deformed tubular members that each comprise:    a first tubular portion, a second tubular portion, and an intermediate tubular portion coupled between the first and second tubular portions; and    a sealing member coupled to the exterior surface of the intermediate tubular portion that engages the interior surface of the casing,    wherein the intermediate tubular portion is radially expanded and plastically deformed, and    wherein the first and second tubular portions are not radially expanded and plastically deformed.
