Subsea well intervention

Abstract

A method is provided for at least one of evaluating and intervening in a subsea well. In one embodiment, the method includes providing a pipeline connecting a platform to the subsea well; coupling a locomotion module with one or more tools; activating the locomotion module to convey the one or more tools from the platform to the subsea well through the pipeline; and operating the one or more tools to perform at least one of an evaluation operation and an intervention operation on the subsea well.

       7 . The method of  claim 1 , wherein the central processing unit module comprises a processor and a memory having one or more program instructions executable by the processor to control operations of the one or more tools.  
   
   
       8 . The method of  claim 1 , wherein the pipeline comprises a bypass line.  
   
   
       9 . The method of  claim 8 , further comprising accessing the subsea well through the bypass line.  
   
   
       10 . The method of  claim 8 , wherein a portion of the bypass line that is coupled to a wellhead of the subsea well is at an obtuse angle with respect to a production tubing disposed inside the subsea well.  
   
   
       11 . The method of  claim 1 , wherein the locomotion module comprises a tractor.  
   
   
       12 . The method of  claim 1 , wherein the pipeline connects the platform to more than one subsea well  
   
   
       13 . A method for at least one of evaluating and intervening in a subsea well, comprising: 
 providing a pipeline connecting a platform to the subsea well;    placing an intervention system in the pipeline, wherein the intervention system comprises a locomotion module, a communication module and one or more intervention tools;    activating the locomotion module to convey the intervention system from the platform to the subsea well through the pipeline; and    operating the one or more tools to perform at least one of an evaluation operation and an intervention operation on the subsea well.    
   
   
       14 . The method of  claim 13 , wherein the communication module is operable to communicate between the one or more intervention tools and a controller disposed on the surface.  
   
   
       15 . The method of  claim 14 , further comprising coupling the communication module to a wireline.  
   
   
       16 . The method of  claim 14 , wherein wireless communication is enabled between the controller and the communication module.  
   
   
       17 . The method of  claim 16 , wherein the communication module is in communication with one or more wireless repeaters disposed along the pipeline.  
   
   
       18 . The method of  claim 13 , wherein the intervention system further comprises a central processing unit module that is operable to control the operation of the intervention tools.  
   
   
       19 . The method of  claim 18 , wherein the central processing unit module comprises a processor and a memory having one or more program instructions executable by the processor to control the operation of the intervention tools.  
   
   
       20 . The method of  claim 13 , wherein the pipeline comprises a bypass line.  
   
   
       21 . The method of  claim 20 , further comprising accessing the subsea well through the bypass line, and wherein a portion of the bypass line that is coupled to a wellhead of the subsea well is at an obtuse angle with respect to a production tubing disposed inside the subsea well.  
   
   
       22 . The method of  claim 20 , wherein a portion of the bypass line that is coupled to a wellhead of the subsea well is substantially in line with a production tubing disposed inside the subsea well.
