Setting mechanical barriers in a single run

Abstract

An operation may require isolation of a wellbore using multiple barriers. A single-run multiple barrier system may be deployed in a wellbore to position a first barrier at a first depth and a second barrier at second depth above the first barrier in the wellbore during a single run of a wellbore tubular string. The first barrier is coupled to a first miming tool. A wellbore tubular string segment couples the first miming tool is coupled to the second barrier. The second barrier is coupled to a second running tool that couples to the wellbore tubular string. The second barrier is locked until the first barrier is independently set at the first depth to prevent the second barrier from being set until the second depth is reached. Setting both barriers in a single run increases efficiency in an operation including reducing costs and time for completion of the operation.

What is claimed is: 
     
         1 . A method of setting a single-run multiple barrier system comprising:
 deploying a single-run multiple barrier system on a wellbore tubular string in a wellbore of a formation, wherein the single-run multiple barrier system comprises a deep set barrier system at a distal end of the wellbore tubular string and a shallow set barrier above the deep set barrier system;   determining if a first depth in the wellbore has been reached by the single-run multiple barrier system;   setting a first isolation device of the deep set barrier system, wherein the shallow set barrier system comprises a rupture disk that prevents a lug from moving within a continuous j-slot to prevent setting of the shallow set barrier system during setting of the first isolation device;   disconnecting the deep set barrier system from the wellbore tubular string;   retrieving the wellbore tubular string to a second depth;   setting a second isolation device of the shallow set barrier system; and   disconnecting the shallow set barrier system from the wellbore tubular string.   
     
     
         2 . The method of  claim 1 , wherein setting the second device comprises:
 rupturing the rupture disk;   allowing the lug to move within the continuous j-slot; and   lifting upward and pushing downward on the wellbore tubular string.   
     
     
         3 . The method of  claim 1 , wherein the first isolation device is coupled to a first running tool, and wherein disconnecting the deep set barrier system from the wellbore tubular string comprises disengaging the first running tool from the wellbore tubular string. 
     
     
         4 . The method of  claim 1 , wherein the shallow set barrier system is coupled to a second running tool, wherein the second running tool is coupled to the wellbore tubular string, and wherein disconnecting the shallow set barrier system from the wellbore tubular string comprises disengaging the second running tool from the wellbore tubular string. 
     
     
         5 . The method of  claim 1 , further comprising: extending one or more first projections of one or more first anchors of the deep set barrier system to contact at least one of the wellbore, an annulus disposed within the wellbore, and a casing disposed within the wellbore. 
     
     
         6 . The method of  claim 1 , further comprising: extending one or more second projections of one or more second anchors of the shallow set barrier system to contact at least one of the wellbore, an annulus disposed within the wellbore, and a casing disposed within the wellbore.

         9 . The method of  claim 1 , wherein at least one of the first setting depth and the second setting depth is based on one or more parameters of the formation. 
     
     
         10 . The method of  claim 1 , further comprising: retrieving the wellbore tubular string from the wellbore.

         12 . The single-run multiple barrier system of  claim 11 , wherein the locking assembly comprises a rupture disk that prevents a lug from moving within a continuous j-slot to prevent setting of the shallow set barrier system during setting of the first isolation device. 
     
     
         13 . The single-run multiple barrier system of  claim 12 , wherein the lug moves within the continuous j-slot when the rupture disk ruptures to set the second isolation device.
