Abstract

A method may include injecting a sealing material into an annulus formed between a tubular and a wellbore wall. The sealing material is configured to surround at least a portion of a control line disposed in the annulus. Further, the method includes making at least one orbital cut, via a cutting device, through the tubular, the sealing material in the annulus, and the control line surrounded by the sealing material. Additionally, the method includes filling the at least one orbital cut and at least a portion of a central bore of the tubular with additional sealing material to seal the wellbore.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method, comprising:
 running a primary plug into a wellbore to a sealing position in a tubular disposed in the wellbore;   perforating the tubular above the primary plug, via a perforating device, to open a first fluid path and a second fluid path each extending between a central bore of the tubular and an annulus formed between the tubular and a wellbore wall, wherein the first fluid path and the second fluid path are axially offset from each other along the wellbore;   running a secondary plug into the wellbore to a position between the first fluid path and the second fluid path;   injecting a sealing material, via a conveyance, through the secondary plug and into the annulus via the first fluid path from the central bore of the tubular, wherein the sealing material is configured flow into the annulus to a position uphole from the secondary plug in the central bore to surround at least a portion of a control line disposed uphole from the secondary plug, and   making at least one orbital cut through the tubular, the sealing material in the annulus, and the control line surrounded by the sealing material, via a cutting device, at a position uphole the secondary plug; and   injecting sealing material into the wellbore to fill areas removed by the cutting device to seal the wellbore.   
     
     
         2 . The method of  claim 1 , wherein the perforating device is configured to perforate the tubular to form a first perforation zone comprising the first fluid path and to form a second perforation zone comprising the second fluid path, and wherein a non-perforated zone is disposed between the first perforation zone and the second perforation zone. 
     
     
         3 . The method of  claim 2 , wherein the secondary plug is configured to be positioned in the non-perforated zone between the first perforation zone and the second perforation zone. 
     
     
         4 . The method of  claim 1 , wherein a portion of the sealing material is configured to flow from the annulus into the central bore, via the second fluid path, in response to injecting the sealing material. 
     
     
         5 . The method of  claim 4 , further comprising:
 removing the conveyance from the wellbore after injecting the sealing material through the secondary plug and into the annulus; and   circulating fluid in the central bore to remove the sealing material disposed in the central bore above the secondary plug.   
     
     
         6 . The method of  claim 1 , wherein the cutting device comprises an abrasive jetting device, a blade cutter, a reamer, a plasma torch, or some combination thereof. 
     
     
         7 . The method of  claim 1 , wherein the perforating device comprises a perforating gun having shaped charges configured to detonate in a substantially radially outward direction to perforate the tubular above the primary plug to open the first fluid path and the second fluid path. 
     
     
         8 . The method of  claim 1 , wherein the perforating device comprises an abrasive jetting device, a blade cutter, a reamer, a plasma torch, or some combination thereof, and wherein the cutting device is configured to perforate the tubular above the primary plug to open the first fluid path and the second fluid path. 
     
     
         9 . The method of  claim 1 , wherein the sealing material is injected into the annulus in at least a partially liquid state, and wherein the sealing material is configured to solidify in the annulus to restrain lateral movement of the control line. 
     
     
         10 . The method of  claim 1 , wherein the sealing material comprises cement, plastic, resin, or some combination thereof. 
     
     
         11 . The method of  claim 1 , wherein the secondary plug include a check-valve configured to restrain fluid flow in the uphole direction, and wherein the sealing material is configured to be injected through the check-valve of the secondary plug. 
     
     
         12 . The method of  claim 1 , further comprising running the cutting device to a position between the secondary plug and the second fluid path, and wherein the at least one orbital cut is made at the position between the secondary plug and the second fluid path. 
     
     
         13 . The method of  claim 1 , wherein the cutting device is run-in-hole via a cutting device conveyance, wherein the cutting device conveyance comprises a slickline, a wireline, coiled tubing, drill pipe, or some combination thereof. 
     
     
         14 . A method, comprising:
 running a primary plug into a wellbore to a sealing position in a tubular disposed in the wellbore;   perforating the tubular above the primary plug, via a perforating gun, to open at least one fluid path between a central bore of the tubular and an annulus formed between the tubular and a wellbore wall;   running a secondary plug into the wellbore to a position above the at least one fluid path;   injecting cement through the secondary plug and into the annulus via the at least one fluid path from the central bore of the tubular, wherein the cement is configured flow into the annulus to a position uphole from the secondary plug in the central bore to surround at least a portion of a control line disposed uphole from the secondary plug;   making at least one orbital cut at a position uphole the secondary plug, via a cutting device, through the tubular, the cement in the annulus, and the control line surrounded by the cement; and   injecting additional cement into the wellbore to fill areas removed by the cutting device to seal the wellbore.   
     
     
         15 . The method of  claim 14 , wherein the secondary plug comprises a check-valve configured to restrain fluid flow in an uphole direction. 
     
     
         16 . The method of  claim 14 , wherein the cement is pushed downhole through the secondary plug via a dart driven downhole with fluid pressure from a cleaning fluid. 
     
     
         17 . The method of  claim 14 , wherein the cement is injected through the secondary plug via an injection conveyance, wherein the injection conveyance comprises drill pipe, coiled tubing, or some combination thereof. 
     
     
         18 . The method of  claim 17 , further comprising pulling the injection conveyance out-of-hole and running high pressure fluid into the tubular to remove the cement disposed uphole from the secondary plug. 
     
     
         19 . A method, comprising:
 running a primary plug into a wellbore to a sealing position in a tubular disposed in the wellbore;   perforating the tubular above the primary plug, via a perforating gun, to open a first fluid path and a second fluid path each extending between a central bore of the tubular and an annulus formed between the tubular and a wellbore wall, wherein the first fluid path and the second fluid path are axially offset from each other along the wellbore;   running a secondary plug into the wellbore to a position between the first fluid path and the second fluid path;   injecting cement, via a conveyance, through the secondary plug and into the annulus via the first fluid path from the central bore of the tubular, wherein the cement is configured flow into the annulus to a position uphole from the secondary plug in the central bore to surround at least a portion of a control line disposed uphole from the secondary plug, and wherein a portion of the cement is configured to flow from the annulus into the central bore via the second fluid path;   removing the conveyance from the wellbore;   circulating fluid in the central bore to remove the cement disposed in the central bore above the secondary plug;   making at least one orbital cut through the tubular, the cement in the annulus, and the control line surrounded by the cement, via a cutting device, at a position uphole the secondary plug; and   injecting cement into the wellbore to fill areas removed by the cutting device to seal the wellbore.
