Electric submersible pump assembly
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.
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 shroud aperture wellbore fluid that has flowed through the first shroud aperture;
wherein the first shroud aperture is capable of receiving wellbore fluid that exited the second 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 . 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 first 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;
wherein the first shroud portion is capable of receiving wellbore fluid that exited the second shroud portion.
9 . The electric submersible pump assembly of claim 8 , wherein the first shroud portion has a first shroud aperture through which wellbore fluid is capable of flowing into the shroud.
10 . The electric submersible pump assembly of claim 8 , wherein the second shroud portion has a second shroud aperture through which wellbore fluid is capable of flowing out of the shroud.
11 . The electric submersible pump assembly of claim 8 , wherein the first pump is between the first shroud portion and the second pump.
12 . The electric submersible pump assembly of claim 8 , wherein the second pump is between the first pump and the first shroud portion.
13 . 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;
wherein the first shroud aperture is capable of receiving wellbore fluid that exited the second shroud aperture.
14 . The electric submersible pump assembly of claim 13 , wherein the motor is below the second pump.
15 . The electric submersible pump assembly of claim 13 , wherein the second pump is capable of pumping out of the second shroud aperture wellbore fluid that has flowed through the first shroud aperture.
