摘要
A riser is installed which extends from a wellhead near the sea floor to near sea level. An electrical submersible pump assembly is suspended within the riser to pump well fluids up the riser. The electrical submersible pump includes impellers for displacing well fluids, and a base member having an intake port for receiving well fluid. The pump assembly can also include a separator for separating any gases from the well fluids, a packer for sealing the pump to the riser, coiled tubing from the pump to at least the upper end of the riser, or NPSH stages to aid in pumping a mixed flow of well fluids and gas.
