Abstract

A submersible pumping system for use in producing wellbore fluids from a wellbore within a subterranean formation includes a motor and a pump driven by the motor to produce the wellbore fluids. The pumping system further includes a self-supporting power cable connected to the pump. The self-supporting power cable includes a plurality of conductors and a plurality of strength members. A method of deploying and retrieving a submersible pumping system in a wellbore includes the steps of connecting a wireline to the submersible pumping system, connecting a self-supporting power cable to the submersible pumping system, lowering the submersible pumping system into the wellbore while the weight of the submersible pumping system is borne by the wireline. The method continues with the step of locating the submersible pumping system on a landing assembly, disconnecting the wireline from the submersible pumping system, and retrieving the wireline from the wellbore without removing the submersible pumping system from the wellbore.

First claim

What is claimed is:

1. A method of deploying and retrieving a submersible pumping system in production tubing within a wellbore, the method comprising the steps of:
connecting a wireline to the submersible pumping system;
lowering the submersible pumping system into the production tubing, wherein the weight of the submersible pumping system is borne by the wireline during the descent;
locating the submersible pumping system on a landing assembly;
disconnecting the wireline from the submersible pumping system;
retrieving the wireline from the submersible pumping system;
lowering a self-supporting power cable to the submersible pumping system;
connecting the self-supporting power cable to the submersible pumping system; and
providing electric current to the submersible pumping system through the self-supporting power cable.

2. The method of claim 1 , further comprising the step of retrieving the submersible pumping system from the wellbore.

3. The method of claim 2 , wherein the step of retrieving the submersible pumping system from the wellbore comprises the step of lifting the submersible pumping system with the self-supporting power cable.

4. The method of claim 2 , wherein the step of retrieving the submersible pumping system comprises:
lowering a wireline to the submersible pumping system;
connecting the wireline to the submersible pumping system; and
lifting the submersible pumping system out of the wellbore with the wireline.

5. The method of claim 1 , further comprising the steps of:
releasing the self-supporting power cable from the submersible pumping system;
retrieving the self-supporting power cable from the wellbore; and
retrieving the submersible pumping system from the wellbore.

6. The method of claim 5 , wherein the step of retrieving the submersible pumping system further comprises:
lowering a wireline to the submersible pumping system;
connecting the wireline to the submersible pumping system; and
lifting the submersible pumping system out of the wellbore with the wireline.

7. The method of claim 1 , wherein the step of locating the submersible pumping system on a landing assembly comprises contacting a landing flange near an upper end on the submersible pumping system on a landing collar within the production tubing.

8. The method of claim 1 , wherein the step of locating the submersible pumping system on a landing assembly comprises contacting a landing assembly near a lower end of the production tubing with a lower end of the submersible pumping system.
