Abstract

A method of removing fluid from a well using a downhole pump includes deploying the downhole pump to a vertical position within a production tubing disposed in the well, securing the downhole pump to the production tubing at the vertical position, powering a motor of the downhole pump with an electrical line of the downhole pump that extends from a surface of the well and that terminates at a profile of the downhole pump, and activating the motor to pump fluid out of the well.

First claim

What is claimed is:

1. A method of removing fluid from a well using a downhole pump, the method comprising:
deploying the downhole pump to a vertical position within a production tubing disposed in the well;
securing the downhole pump to the production tubing at the vertical position;
powering a motor of the downhole pump with an electrical line of the downhole pump that extends from a surface of the well to the downhole pump;
activating the motor to pump fluid out of the well,
collecting production data from the motor while the fluid is pumped out with a control line of the downhole pump that extends from the surface to the downhole pump, wherein the electrical line and the control line terminate at a profile of the downhole pump above a packer of the downhole pump to allow for powering the downhole pump and controlling the downhole pump from the surface; and
removing the fluid from the well using the downhole pump without having installed a permanent pump receptacle within the production tubing beneath the downhole pump.

2. The method of claim 1 , wherein securing the downhole pump to the production tubing comprises inflating a packer of the downhole pump to seal the packer against an inner surface of the production tubing at the vertical position.

3. The method of claim 2 , wherein the vertical position is a first vertical position, the method further comprising:
deflating the packer;
moving the downhole pump to a second vertical position that is different from the first vertical position; and
re-inflating the packer to seal the packer against the inner surface of the production tubing at the second vertical position.

4. The method of claim 2 , further comprising:
determining that the well is substantially clean;
deflating the packer to release the downhole pump from the production tubing; and
withdrawing the downhole pump from the well.

5. The method of claim 1 , wherein the electrical line is integrated with a deployment cable on which the downhole pump is deployed.

6. The method of claim 1 , wherein the electrical line is a separate component from a deployment cable on which the downhole pump is deployed.

7. The method of claim 1 , wherein the control line is integrated with a deployment cable on which the downhole pump is deployed.

8. The method of claim 1 , wherein the control line is a separate component from a deployment cable on which the downhole pump is deployed.

9. The method of claim 1 , further comprising removing the fluid from the well using the downhole pump without attaching the downhole pump to a pump receptacle within the production tubing.

10. The method of claim 1 , wherein the electrical line and the control line extend laterally along the downhole pump within a protective sleeve that surrounds the downhole pump.

11. A downhole pump for removing fluids from a well, the downhole pump comprising:
a motor for pumping fluids out of the well;
an electrical line coupled to the motor for powering the motor and extending from a surface of the well;
a control line coupled to the motor for collecting production data from the motor and extending from the surface of the well; and
an inflatable packer coupled to the motor for securing the downhole pump to a production tubing within the well at a vertical position,
wherein the electrical line and the control line terminate at a profile of the downhole pump above the inflatable packer to allow for powering the downhole pump and controlling the downhole pump from the surface, such that downhole pump is configured to be installed in the production tubing without being assembled with a permanent downhole pump receptacle.

12. The downhole pump of claim 11 , wherein the inflatable packer is configured to seal against an inner surface of the production tubing.

13. The downhole pump of claim 11 , wherein the electrical line is integrated with a deployment cable on which the downhole pump is deployable.

14. The downhole pump of claim 11 , wherein the electrical line is a separate component from a deployment cable on which the downhole pump is deployable.

15. The downhole pump of claim 11 , wherein the control line is integrated with a deployment cable on which the downhole pump is deployable.

16. The downhole pump of claim 11 , wherein the control line is a separate component from a deployment cable on which the downhole pump is deployable.

17. The downhole pump of claim 11 , wherein the electrical line and the control line extend laterally along the downhole pump.

18. The downhole pump of claim 17 , further comprising a sleeve that surrounds at least a portion of the electrical line and the control line.
