Abstract: The downhole electromagnetic pump includes a pumping chamber that is provided with a throughbore through which fluid may be pumped. An electrode arrangement is provided in order to produce an electro-hydro-dynamic force on fluids within the pump such that fluid may be pumped through the pump in a desired direction. A method of utilizing the downhole electromagnetic pump in order to pump fluids in a downhole environment is also provided.

Abstract: The invention relates to a method of positioning a pump in a well in order to create artificial lift. The method involves frictionally engaging a portion of the pump with a portion of the well, such that the pump is retained in a starting position. In order to progress the pump into the well, the pressure differential across the pump is increased, and then, when the pump is in a finishing position, the pressure differential across the pump is reduced such that the pump is once again retained in the finishing position by the frictional engagement between the pump and the well. A pump for use in the above method of deployment is also provided.
