Method and system for positioning a magnetic fluid conditioner

Abstract

This disclosure presents methods and systems for positioning a magnetic fluid conditioner in a well. One or more magnetic fluid conditioners are attached to a coupling mandrel operable to engage with the tubing of a well, either with an existing completion component or directly with the tubing. The coupling mandrel includes a locking mechanism, such as keys or dogs, for setting the mandrel to the profile nipple. The coupling mandrel further includes a packing stack or an expandable element that seals with the completion component or the tubing. The seal directs oil through the mandrel and thus, through the magnetic fluid conditioners. In some embodiments, multiple magnetic fluid conditioners are attached in tandem for more effective conditioning operations. The magnetic fluid conditioners can condition the oil to inhibit the formation of paraffin therein.

What is claimed is: 
     
         1 . A method for positioning a magnetic fluid conditioner in a tubing positioned within a casing of a producing well, the tubing having a completion component having at least a tubular wall with an internal surface to provide a seal area, the method comprising:
 inserting a coupling mandrel having the magnetic fluid conditioner coupled at a distal portion of the coupling mandrel into the tubing positioned within the casing of the well;   positioning the coupling mandrel at least partially within the completion component, wherein the completion component of the tubing interfaces at least partially with the coupling mandrel to position the magnetic fluid conditioner within an internal volume of the tubing and radially surrounded by the tubing; and   sealing the coupling mandrel with the tubing such that when fluids are flowing from below from the producing well, these fluids are directed to flow through the magnetic fluid conditioner and at least a portion of the coupling mandrel such that these fluids cannot flow through the tubing past the seal area without flowing through the magnetic fluid conditioner.   
     
     
         2 . The method of  claim 1 , further comprising locking the coupling mandrel at a locking profile of the completion component, wherein locking the coupling mandrel to the locking profile comprises expanding a set of locking keys of the coupling mandrel to engage the locking profile of the completion component. 
     
     
         3 . The method of  claim 1 , wherein sealing the coupling mandrel with the tubing includes using the seal area of the completion component and comprises placing a packing stack in contact with the seal area, wherein the seal area provides a sealable portion to receive the packing stack. 
     
     
         4 . The method of  claim 1 , wherein the completion component is a profile nipple placed at a desired position of the well to allow accurate placement of the magnetic fluid conditioner. 
     
     
         5 . The method of  claim 2 , wherein locking the coupling mandrel to the locking profile comprises engaging the locking profile via a spring-loaded locking dog on the coupling mandrel when the spring-loaded locking dog is adjacent the locking profile. 
     
     
         6 . The method of  claim 1 , wherein sealing the coupling mandrel with the tubing includes sealing the coupling mandrel with at least a section of tubular wall of the completion component with an internal surface of the tubing to provide the seal area. 
     
     
         7 . The method of  claim 1 , wherein positioning the coupling mandrel at least partially within the completion component comprises positioning the coupling mandrel such that the magnetic fluid conditioner is not in direct contact with the tubing. 
     
     
         8 . A method for positioning a magnetic fluid conditioner in a tubing positioned within a casing of a well, the method comprising:
 inserting a mandrel into the tubing positioned within the casing of the well;   positioning the mandrel with the magnetic fluid conditioner such that the magnetic fluid conditioner is positioned in an internal volume of the tubing and is positioned below a distal portion of the mandrel further into the tubing of the well;   expanding a plurality of locking members of the mandrel to engage internal walls of the tubing when the mandrel is at a desired position in the tubing; and   sealing the mandrel with respect to the internal walls of the tubing such that when fluids are flowing from below from the well, these fluids are directed to flow through the magnetic fluid conditioner and the mandrel, wherein the magnetic fluid conditioner is in fluid communication with the mandrel within the internal volume of the tubing.   
     
     
         9 . The method of  claim 8 , wherein expanding the plurality of locking members of the mandrel further comprises pulling up the distal portion of the mandrel to displace a plurality of slips surrounding the distal portion of the mandrel as to expand the plurality of slips and the plurality of locking members thereon to bite against the internal walls of the tubing. 
     
     
         10 . The method of  claim 8 , wherein the mandrel with the magnetic fluid conditioner includes more than one magnetic fluid conditioner coupled in tandem. 
     
     
         11 . The method of  claim 8 , wherein the fluids directed to flow through the magnetic fluid conditioner further comprises conditioning the fluids to inhibit the formation of paraffin. 
     
     
         12 . The method of  claim 8 , wherein the desired position of the mandrel in the tubing is provided using a profile nipple positioned inside the tubing. 
     
     
         13 . The method of  claim 8 , wherein inserting the mandrel into the tubing of the well comprises lowering the mandrel into the tubing using a slick line (wire line), an E line, or a coil tubing connected to a fishing neck of the mandrel. 
     
     
         14 . A system for positioning a magnetic fluid conditioner in a tubing positioned within a casing of a well, the system comprising:
 a completion component positioned at a first location of the tubing, the completion component comprising at least a portion of tubular wall with a locking profile;   a coupling mandrel configured to be connected to the magnetic fluid conditioner, the magnetic fluid conditioner in fluid communication with the coupling mandrel at a distal portion of the coupling mandrel and below the coupling mandrel, the completion component configured to position the coupling mandrel with the magnetic fluid conditioner connected to the coupling mandrel; and   wherein a portion of the coupling mandrel is configured to be sealed against a seal area of the tubing and is configured to direct fluids below the seal area to flow through the magnetic fluid conditioner for magnetic conditioning of the fluids.
