Abstract
A process for controlling the production of loose sand particles within an underground formation through the use of magnetic forces is provided. The loose sand particles are magnetized and then subjected to a magnetic field of sufficient strength such that the operator can control the movement of the loose sand particles within the underground formation. In some instances, the present invention can provide an efficient process for keeping the loose sand particles within the formation, and thereby prolonging the useful life of the downhole equipment. In other instances, the present invention can provide an efficient process for sweeping the loose sand particles out of the underground formation in a controlled fashion. The present invention includes at least three embodiments for magnetizing the loose sand particles, including direct magnetization, contacting the sand particles with a magnetizing reagent, and contacting the sand particles with paramagnetic nanoparticles.
