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.
