Method and system for running barrier valve on production string

Abstract

A completion system, including a lower completion initially fluidly open. A production string is included having a removable plug configured to impede fluid flow through the production string. The removable plug is run in with the production string. An intermediate completion assembly is included that couples the lower completion to the production string. The intermediate completion assembly has a packer device and a barrier valve. The packer device is operatively arranged to be set by pressurizing fluid in the production string against the removable plug. The barrier valve is operatively arranged for selectively impeding fluid flow between the production string and the lower completion after the removable plug is removed. A method of completing a borehole is also included.

What is claimed is: 
     
         1 . A completion system, comprising:
 a lower completion initially fluidly open;   a production string having a removable plug configured to impede fluid flow through the production string, the removable plug being run in with the production string; and   an intermediate completion assembly coupling the lower completion to the production string, the intermediate completion assembly having a packer device and a barrier valve, the packer device operatively arranged to be set by pressurizing fluid in the production string against the removable plug, the barrier valve operatively arranged for selectively impeding fluid flow between the production string and the lower completion after the removable plug is removed.   
     
     
         2 . The completion system of  claim 1 , wherein the removable plug is operatively arranged to be removed by exposure to a downhole fluid. 
     
     
         3 . The completion system of  claim 1 , wherein the downhole fluid comprises brine, acid, water, oil, or a combination including at least one of the foregoing. 
     
     
         4 . The completion system of  claim 1 , wherein the production string comprises an artificial lift system. 
     
     
         5 . The completion system of  claim 1 , wherein the production string includes at least one component prohibiting passage of a plugging implement therethrough. 
     
     
         6 . The completion system of  claim 1 , wherein the barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitioning to a closed position via the upper completion string when the upper completion string is pulled out of the borehole. 
     
     
         7 . The completion system of  claim 1 , further comprising a subsequent intermediate assembly stacked with the intermediate completion assembly, the subsequent intermediate assembly having a subsequent barrier valve and a subsequent packer device for functionally replacing the intermediate completion assembly. 
     
     
         8 . The completion system of  claim 7 , wherein the intermediate completion assembly is engaged between the subsequent intermediate assembly and the lower completion and the subsequent intermediate assembly is engaged between the intermediate completion assembly and the production string. 
     
     
         9 . The completion system of  claim 8 , wherein the production string includes a first tool operatively arranged for enabling the subsequent barrier valve to transition between open and closed positions and the subsequent intermediate assembly is arranged with a second tool for holding the barrier valve in its open position while the subsequent intermediate completion assembly is engaged with the first intermediate assembly. 
     
     
         10 . The completion system of  claim 1 , wherein the intermediate completion assembly includes a shroud enclosing a housing of the barrier valve. 
     
     
         11 . A method of completing a borehole comprising:
 running a production string having a removable plug disposed therewith downhole, an intermediate completion assembly disposed with the production string;   coupling the production string to a lower completion with the intermediate completion assembly, the lower completion initially fluidly open;   impeding fluid flow between the production string and the lower completion with the removable plug;   setting a packer device by pressurizing fluid in the production string against the removable plug;   removing the removable plug; and   impeding fluid flow between the production string and the lower completion with a barrier valve of the intermediate completion assembly.   
     
     
         12 . The method of  claim 11 , further comprising exposing the removable plug to a downhole fluid for removing the removable plug. 
     
     
         13 . The method of  claim 11 , wherein the downhole fluid comprises brine, acid, water, oil, or a combination including at least one of the foregoing. 
     
     
         14 . The method of  claim 11 , wherein the production string comprises an artificial lift system. 
     
     
         15 . The method of  claim 11 , wherein the production string includes at least one component prohibiting passage of a plugging implement therethrough. 
     
     
         16 . The method of  claim 11 , wherein the barrier valve is operatively arranged to be transitionable to an open position when engaged with the upper completion string and transitioning to a closed position via the upper completion string when the upper completion string is pulled out of the borehole. 
     
     
         17 . The method of  claim 11 , further comprising running in a subsequent intermediate assembly and stacking the subsequent intermediate assembly with the intermediate completion assembly, the subsequent intermediate assembly having a subsequent barrier valve and a subsequent packer device for functionally replacing the intermediate completion assembly. 
     
     
         18 . The system of  claim 17 , wherein the intermediate completion assembly is engaged between the subsequent intermediate assembly and the lower completion and the subsequent intermediate assembly is engaged between the intermediate completion assembly and the production string. 
     
     
         19 . The system of  claim 18 , wherein the production string includes a first tool operatively arranged for enabling the subsequent barrier valve to transition between open and closed positions and the subsequent intermediate assembly is arranged with a second tool for holding the barrier valve in its open position while the subsequent intermediate completion assembly is engaged with the first intermediate assembly.
