Abstract
A subsea injection system may include one or more filter stages to filter seawater and output filtered seawater and waste seawater. The waste seawater may include particles removed from the filtered seawater. The subsea injection system may also include a combined pump having an injection pump to motivate the filtered seawater into a reservoir of a geological formation. The combined pump may also include a filter pump to motivate the seawater through the filter stages and a motor to drive the injection pump and the filter pump. The motor may drive the filter pump via an indirect coupling such that the motor is sealed from the filter pump at the indirect coupling.
