Abstract
A magnet shield for use with a magnetic scale inhibitor includes a barrier configured for positioning at a location between the magnetic scale inhibitor and a flowbore for at least a first time period. The flowbore is configured for flow of a fluid. The barrier is: degradable in the fluid, such that, after the first time period, the barrier is no longer present at the location; and/or shiftable, such that, after the first time period, the barrier can be shifted away from the location. During the first time period, the barrier reduces or eliminates attraction of ferromagnetic particles to magnets of the magnetic scale inhibitor. A magnetic scale inhibitor tool comprising the magnet shield and a methods of utilizing the magnet shield and the magnetic scale inhibitor tool comprising the magnet shield are also provided herein.
