A downhole tubular verification and centralizing device, and method

Abstract

A device for centralizing a tubular in a bore, includes a body configured to be positioned at a predetermined location inside the tubular. The device further includes a plurality of penetration tools movably connected to the body via respective motive portions and configured to extend from the body and through the tubular wall. A wall-abutment portion is configured to generate a force between the tubular in order to at least partly shift the tubular inside the bore. The tool, which impinges on the wall, may be extended further, such that the casing is moved as a reaction.

1 . A device for centralizing a tubular in a bore, comprising:
 a body configured to be positioned at a predetermined location inside the tubular;   a plurality of penetration tools movably connected to the body via respective motive portions and configured to extend from the body and through the tubular wall; and   a wall-abutment portion configured to generate a force between the tubular and the bore in order to at least partly shift the tubular inside the bore.   
     
     
         2 . The device of  claim 1 , wherein each of the plurality of penetration tools comprises at least one sensing device configured to sense the distance travelled by the penetration tool. 
     
     
         3 . The device of  claim 1 , wherein each of the plurality of penetration tools comprises at least one sensing device configured for to sense the distance to a wall of the bore. 
     
     
         4 . The device of  claim 1 , wherein each of the plurality of penetration tools are releasably connected to the each of the respective motive portions. 
     
     
         5 . The device of  claim 1 , wherein the plurality of penetration tools comprises three penetration tools arranged at 120° intervals around the body circumference, when viewed in a tubular cross-sectional plane. 
     
     
         6 . The device of  claim 1 , wherein the plurality of penetration tools comprises four penetration tools arranged at 90° intervals around the body circumference, when viewed in a tubular cross-sectional plane. 
     
     
         7 . The device of  claim 1 , wherein at least one of the plurality of penetration tools comprises a milling tool. 
     
     
         8 . A method of centralizing a tubular in a bore, comprising:
 arranging a device according to  claim 1  at a predetermined location inside the tubular;   extending at least one of the plurality of penetration tools radially from the device body to form an opening in a respective portion of the tubular while securing at least a portion of the at least one of the plurality of penetration tools to the tubular; and   extending at least a portion of the at least one of the plurality of penetration tools a predetermined distance towards a wall of the bore, or until at least a portion of one of the plurality of the tools impinges on the wall.   
     
     
         9 . The method of  claim 8 , further comprising further extending at least one of the plurality of tools, which impinges on the wall, to cause the casing to be moved as a reaction. 
     
     
         10 . The method of  claim 8  wherein the device body is disconnected from the tools and retrieved out of the bore once the at least a portion of the plurality of penetration tools is extended a predetermined distance towards the wall of the bore or at least a portion of the plurality of penetrations tools impinges on the wall. 
     
     
         11 . A method of centralizing at least a portion of a tubular in a bore, comprising:
 arranging the device according to  claim 1  at a predetermined first location inside the tubular;   extending at least one of the plurality of penetration tools from the device body to make a first circumferential window in the tubular;   installing a first at least one force member, through the first window, between the tubular outer wall and the bore;   relocating the device to a predetermined second location inside the tubular;   extending at least one of the penetration tools from the device body to make a second circumferential window in the tubular; and   installing a second least one force member, through the second window, between the tubular outer wall and the bore.
