摘要:
In combination, an inverted electric submersible pump (ESP) sized to fit within a downhole production path and a coiled tubing string. The coiled tubing string has an internal bore, and one or more supply lines housed within the internal bore and connected between surface and the inverted ESP. The inverted ESP has a pump section and a motor section, the motor section disposed above the pump section, and the pump section having one or more inlet ports and one or more outlet ports. At least one sealing element is positioned between the one or more inlet ports and the one or more outlet ports and is sized to seal against the downhole production path. A coiled tubing connection sealably connects the motor section to the coiled tubing string.
