Single run system for running liner and suspension plug down hole and method of using same

Abstract

A system and method for running a liner and suspension plug into a wellbore in one run is provided. The single run system features an up hole end and down hole end and comprises a running tool, a suspension plug setting tool, and a plug section. The running tool further comprises a packer assembly which includes at least a packer element and a liner connection. The single run system is run down hole to position the liner and the packer element is activated to secure the liner. The plug running tool detaches from the liner and packer element and is pulled up hole to position the plug section above the liner and packer element. The plug section comprises a suspension plug which is set in the casing above the liner. The remaining elements of the single run system are released from the plug section and pulled up hole.

We claim: 
     
         1 . A single run system for use in setting a liner and a suspension plug in a wellbore comprising:
 a running tool having a downhole end;   a liner releasably connected to the running tool;   a suspension plug setting tool having an up hole end and a downhole end and connected to the downhole end of the running tool via its up hole end; and   a plug section connected to the downhole end of the suspension plug setting tool.   
     
     
         2 . The single run system of  claim 1 , wherein the running tool comprises a setting piston, a locking collet, a ball seat shear sleeve, and tubing flow valve and a packer assembly. 
     
     
         3 . The single run system of  claim 2 , wherein the packer assembly comprises an activation housing and a mandrel. 
     
     
         4 . The single run system of  claim 1 , wherein the plug section comprises a suspension packer, an inflatable packer, a bridge plug or a completion packer. 
     
     
         5 . The single run system of  claim 1 , wherein the plug section comprises a bull plug. 
     
     
         6 . The single run system of  claim 1 , wherein the suspension plug setting tool comprises a top sub and a bottom sub, wherein the top sub and the bottom sub detach when activated. 
     
     
         7 . The single run system of  claim 1 , wherein the suspension plug setting tool is a hydraulic piston style setting tool which shears away from the suspension plug when activated. 
     
     
         8 . A method of setting a liner and a suspension plug in a wellbore having a casing, the method comprising:
 providing a single run system comprising a running tool with a downhole end and comprising a packer assembly, a liner releasably connected to the running tool, a suspension plug setting tool having an up hole end and a downhole end and connected to the downhole end of the running tool via its up hole end, a plug section connected to the downhole end of the suspension plug setting tool;   running the single run system into the wellbore;   activating the running tool to set the packer assembly and install the liner in the wellbore;   detaching the single run system from the liner and the packer assembly, leaving a suspension plug running tool moveable within the wellbore;   pulling the suspension plug running tool up hole such that the suspension plug is positioned above the liner and the packer assembly; and   activating the suspension plug running tool to set the suspension plug inside the casing.   
     
     
         9 . The method of  claim 8 , wherein fluid is able to circulate through the single run system during the running in process. 
     
     
         10 . The method of  claim 8 , wherein the running tool is pressure activated to set the packer assembly and liner. 
     
     
         11 . The method of  claim 8 , wherein the running tool is activated by mechanical means to set the packer assembly and liner. 
     
     
         12 . The method of  claim 8 , wherein the suspension plug is actuated from an unset position to a set position using pressure. 
     
     
         13 . The method of  claim 8 , wherein the suspension plug is actuated from an unset position to a set position using mechanical means. 
     
     
         14 . The method of  claim 8 , wherein the suspension plug setting tool has a top sub and a bottom sub and further comprising activating the suspension plug setting tool to detach the top sub from the bottom sub. 
     
     
         15 . The method of  claim 8 , wherein the suspension plug setting tool completely disconnects from the suspension plug when activated.
