Abstract:
1. A subsea system for use in treating seawater for injection into a subterranean formation comprising: a fluid treatment module comprising a fluid inlet, a first fluid outlet for treated seawater with a reduced concentration of a selected component, and a second fluid outlet for treated seawater with an increased concentration of the selected component; an educator having a motive fluid port, a delivery port, and a suction port; a pump having an inlet and an outlet; wherein the delivery port of the educator is in fluid communication with the fluid inlet of the fluid treatment module; wherein the second fluid outlet of the fluid treatment module is configured for disposal of the treated seawater with the increased concentration of the selected component into the ambient sea, and the suction port of the educator is configured to received ambient seawater from the ambient sea; wherein the pump inlet is in fluid communication with the first fluid outlet of the fluid treatment module for receiving the treated seawater with the reduced concentration of the selected component; and wherein the subsea system is configured for communication of the treated seawater with the reduced concentration of the selected component from the pump outlet to a subterranean formation and for communication of the treated seawater with the reduced concentration of the selected component from the pump outlet to the motive fluid port of the educator so as to entrain seawater from the ambient sea through the suction port of the educator for delivery through the delivery port of the educator to the fluid inlet of the fluid treatment module at a pressure which is greater than a pressure of the ambient sea.
