Multiphase twin screw pumps are used by the oil and gas production industry to boost the
transport of hydrocarbons allowing for a greater field recovery and longer transport distances.
Since Multiphase pumps are considered for remote area and deepwater/ultradeepwater
applications, the pump components that are subjected to wear due to corrosion, erosion and
erosion-corrosion need to be optimized to insure long, uninterrupted periods of operation. This
paper presents the results of an investigation focused on the inhibiting quality of different oil
types due to sufficient entrainment of formation water. The corrosion activity in the clearance
spaces of a multiphase pump where the main metal loss occurs was measured using a single
screw pump model and two electrodes.
