摘要
A method of servicing an electric submersible pump in a well with a positive wellhead pressure includes providing production tubing in the well casing, a coil tubing string within the production tubing having an electric submersible pump at a downhole end of the coil tubing string, and a pump-receiving housing above the injection port of the wellhead. With the injection port sealed and the pump-receiving housing opened, the electric submersible pump may be inserted or removed from the pump-receiving housing. With the pump-receiving housing closed and the injection port opened, the electric submersible pump may be moved to or from the production tubing in the well.
