Patent ID: 8915303

Claim:
A method of servicing an electric submersible pump in a well having a positive wellhead pressure, the well comprising a casing and a wellhead mounted to the casing, the wellhead having a sealable injection port and at least one production port, the method comprising the steps of: providing: a production path in the casing such that production fluids flow up the production path; a coiled tubing string having an electric submersible pump at a downhole end of the coiled tubing string and at least one supply line through the coiled tubing string connected to the electric submersible pump, the electric submersible pump comprising a pump section, a motor section, and a thrust chamber; and a pump-receiving housing above the wellhead and the injection port and seal of the wellhead, the pump-receiving housing being separate and distinct from the seal, the pump-receiving housing being large enough to receive the electric submersible pump, the pump-receiving housing being sealed to atmosphere when the injection port is open, and openable to atmosphere when the injection port is sealed; sealing the pump receiving housing simultaneously above and below the electric submersible pump when the electric submersible pump is received within the pump-receiving housing; sealing the injection port by closing the seal and opening the pump-receiving housing to atmosphere to insert or remove the electric submersible pump from the pump-receiving housing; and with the pump-receiving housing closed to atmosphere and the injection port open, moving the electric submersible pump using a coiled tubing injector to the production path in the well from a position fully received within the pump-receiving housing or from the production path in the well to a position fully received within the pump-receiving housing.
