Abstract
A system and method for producing fluid from a subterranean wellbore that includes an electrical submersible pump (“ESP”) system and a receptacle. The ESP system is landed in the receptacle while sensing the presence of the ESP system with respect to the receptacle. The ESP system includes a motor, a pump, a monitoring sub, and a stinger on the lower end of the pump. A sensor on the receptacle detects the position of the stinger within the receptacle, and provides an indication that the stinger has inserted a designated length into the receptacle so that a fluid tight seal is formed between the stinger and receptacle.
Claims18
A system for producing fluid from a subterranean wellbore comprising:
- an electrical submersible pump (“ESP”) system comprising a pump, a motor mechanically coupled with the pump, a monitoring sub, and a stinger projecting axially away from the pump;
- a receptacle comprising an annular member mounted to a tubular disposed in the wellbore;
- and
- a sensor that selectively emits a signal representing a distance between the stinger and receptacle.
A method for producing fluid from a subterranean wellbore comprising:
- deploying in the wellbore an electrical submersible pumping (“ESP”) system that comprises a motor that is coupled to a pump;
- lowering the ESP system within the wellbore and towards a receptacle;
- sensing a distance between a location on the ESP system and a location in the receptacle;
- and
- pressurizing fluid within the wellbore with the pump when the distance between the end of the ESP system and receptacle is within a designated distance.
