ABSTRACT:
A submersible pumping system for use downhole that includes a housing, a pump and gas separator within the housing, a motor for driving the pump and separator, and a foaming agent injection system. The foaming agent injection system injects a foaming agent upstream of the pump and optionally upstream of the separator. The foaming agent injection system comprises a foaming agent supply, an injection pump, and foaming agent injection line.
