Abstract

Disclosed herein are electric submersible pump assemblies and methods for pumping wellbore fluid that may each include an electric submersible pump assembly which may include: a shroud that may include: a first shroud aperture; and a second shroud aperture; a first pump disposed in the shroud, wherein the first pump may be capable of pumping wellbore fluid that has flowed through the first shroud aperture; and a second pump disposed in the shroud, wherein the second pump may be capable of pumping out of the second aperture wellbore fluid that has flowed through the first shroud aperture.

Claims (43)

1 . An electric submersible pump assembly for pumping fluids from a wellbore, comprising:

a shroud that comprises:

a first shroud aperture; and

a second shroud aperture;

a first pump disposed in the shroud, wherein the first pump is capable of pumping wellbore fluid that has flowed through the first shroud aperture; and

a second pump disposed in the shroud, wherein the second pump is capable of pumping out of the second aperture wellbore fluid that has flowed through the first shroud aperture.

2 . The electric submersible pump assembly of claim 1 , further comprising a shaft rotatably coupled to the first pump and the second pump.

3 . The electric submersible pump assembly of claim 1 , wherein the first pump and the second pump are disposed between the first shroud aperture and the second shroud aperture.

4 . The electric submersible pump assembly of claim 1 , wherein the second pump is below the first pump.

5 . The electric submersible pump assembly of claim 1 , wherein the first pump is capable of pumping wellbore fluid away from the second pump.

6 . The electric submersible pump assembly of claim 1 , wherein the second pump is capable of pumping wellbore fluid away from the first pump.

7 . The electric submersible pump assembly of claim 1 , wherein the first pump is capable of pumping wellbore fluid in a first direction and the second pump is capable of pumping wellbore fluid in a second direction that is opposite the first direction.

8 . The electric submersible pump assembly of claim 1 , wherein the second pump is capable of pumping wellbore fluid away from the first pump.

9 . An electric submersible pump assembly for pumping fluids from a wellbore, comprising:

a shroud that comprises:

a first shroud portion; and

a second shroud portion;

a first pump disposed in the shroud, wherein the second pump is capable of pumping wellbore fluid past the first shroud portion; and

a second pump disposed in the shroud wherein the second pump is capable of pumping wellbore fluid out through the second shroud portion.

10 . The electric submersible pump assembly of claim 9 , wherein the first shroud portion has a first shroud aperture through which wellbore fluid is capable of flowing into the shroud.

11 . The electric submersible pump assembly of claim 9 , wherein the second shroud portion has a second shroud aperture through which wellbore fluid is capable of flowing out of the shroud.

12 . The electric submersible pump assembly of claim 9 , wherein the first pump is between the first shroud portion and the second pump.

13 . The electric submersible pump assembly of claim 9 , wherein the second pump is between the first pump and the first shroud portion.

14 . An electric submersible pump assembly for pumping fluids from a wellbore, comprising:

a shroud that comprises:

a first shroud aperture; and

a second shroud aperture;

a first pump disposed in the shroud;

a second pump disposed in the shroud, wherein the second pump is capable of pumping wellbore fluid out of the second shroud aperture;

a motor; and

a shaft rotatably coupled to the motor, the first pump, and the second pump.

15 . The electric submersible pump assembly of claim 14 , wherein the motor is below the second pump.

16 . The electric submersible pump assembly of claim 14 , wherein the second pump is capable of pumping out of the second shroud aperture wellbore fluid that has flowed through the first shroud aperture.

17 . An electric submersible pump assembly for pumping fluids from a wellbore, comprising:

a shroud;

a first pump disposed in the shroud;

a second pump disposed in the shroud; and

an intake conduit disposed between the first pump and the second pump, the intake conduit having:

a first intake aperture in fluid communication with the first pump; and

a second intake aperture in fluid communication with the second pump.

18 . The electric submersible pump assembly of claim 17 , wherein the first pump is above the intake conduit.

19 . The electric submersible pump assembly of claim 17 , wherein the first pump is below the intake conduit.

20 . The electric submersible pump assembly of claim 17 , wherein the first intake aperture has a first diameter that is greater than second diameter of the second intake aperture.
