Abstract

A system includes a fluid injection system. The fluid injection system includes a rotary isobaric pressure exchanger (IPX) configured to receive a first fluid, to receive a second fluid extracted from a source well, to utilize the second fluid to pressurize the first fluid for injection into an injection well, and to inject the pressurized first fluid into the injection well.

First claim

What is claimed is:

1. A system, comprising:
a fluid transportation system configured to transport oil, comprising:
a separator configured to separate a multi-phase fluid extracted from a source well into a plurality of components, wherein the plurality of components comprises at least the oil;
a rotary isobaric pressure exchanger (IPX) configured to receive the oil from the separator, to receive the multi-phase fluid extracted from the source well, to utilize the multi-phase fluid to pressurize the oil to enable transport of the oil from the rotary IPX to a designated location;
wherein the oil is derived from the multi-phase fluid by the separator subsequent to the multi-phase fluid passing through the rotary IPX.

2. The system of claim 1 , wherein the designated location is located above a sea surface.

3. The system of claim 2 , wherein the designated location comprises an oil platform.

4. The system of claim 2 , wherein the designated location comprises a vessel.

5. The system of claim 2 , wherein the designated location is located onshore.

6. The system of claim 1 , wherein the separator is disposed on a platform above the sea surface.

7. The system of claim 1 , wherein the rotary IPX is disposed on a platform above the sea surface.

8. The system of claim 1 , wherein the rotary IPX is disposed below the sea surface.

9. The system of claim 1 , wherein the separator is disposed below the sea surface.

10. A system, comprising:
a fluid transportation system, comprising:
a rotary isobaric pressure exchanger (IPX) configured to receive oil derived from a multi-phase fluid extracted from a source well, to receive the multi-phase fluid extracted from the source well, to utilize the multi-phase fluid to pressurize the oil to enable transport of the oil from the rotary IPX to a designated location;
wherein the oil is derived from the multi-phase fluid by a separator subsequent to the multi-phase fluid passing through the rotary IPX.

11. The system of claim 10 , wherein the designated location is located above a sea surface.

12. The system of claim 10 , wherein the designated location is located onshore.

13. A method for utilizing a fluid transportation system in a hydrocarbon extraction operation, comprising:
extracting a high pressure, multi-phase fluid from a source well;
utilizing a rotary isobaric pressure exchanger (IPX) to receive oil derived from the high pressure, multi-phase fluid extracted from the source well and to pressurize oil using the high pressure, multi-phase fluid;
separating, via a separator, the oil from the high pressure, multi-phase fluid subsequent to the high pressure, multi-phase fluid being utilized to pressurize the oil; and
transporting a pressurized oil from the rotary IPX to a designated location.
