Abstract
A gas-oil separation plant (GOSP) is configured to process crude oil produced from a well. A production stream from the well operates at a first pressure. A processed crude oil stream from the GOSP flows to a multi-phase ejector. The multi-phase ejector induces flow of a production stream from the well in response to the flow of the processed crude oil stream.
Claims9
A method comprising:
- flowing, by a pump of a gas-oil separation plant, a processed crude oil stream at a first pressure to a multi-phase ejector fluidically coupled to the pump and fluidically coupled to a well;
- creating, by the multi-phase ejector, a low-pressure area responsive to flowing the processed crude oil stream, thereby inducing flow of a production stream from the well to the multi-phase ejector at a second pressure less than the first pressure, wherein a pressure in the low-pressure area is less than the second pressure of the production stream;
- flowing a mixture of the processed crude oil stream and a first portion of the production stream from the multi-phase ejector to a low pressure production trap of the gas-oil separation plant;
- flowing a second portion of the production stream from the well to a high pressure production trap of the gas-oil separation plant;
- and
- flowing a third portion of the production stream from the well to a high pressure test trap of the gas-oil separation plant, wherein the flow of the production stream from the well is induced without decreasing an operating pressure of the high pressure production trap, thereby avoiding increasing a load to a flare of the gas-oil separation plant.

A system comprising:
- a multi-phase ejector fluidically coupled to a well;
- a pump in a gas-oil separation plant fluidically coupled to the multi-phase ejector, the pump configured to flow a processed crude oil stream as motive fluid to the multi-phase ejector at a first pressure, wherein the multi-phase ejector is configured to create a low-pressure area in response to the flow of the processed crude oil stream, thereby inducing flow of a production stream from the well as suction fluid to the multi-phase ejector at a second pressure less than the first pressure, wherein a pressure in the low-pressure area is less than the second pressure;
- a low pressure production trap in the gas-oil separation plant, wherein the multi-phase ejector is configured to discharge a mixture of the processed crude oil stream and a first portion of the production stream to the low pressure production trap;
- a high pressure production trap in the gas-oil separation plant, wherein the high pressure production trap is configured to receive a second portion of the production stream from the well;
- and
- a high pressure test trap in the gas-oil separation plant, wherein the high pressure test trap is configured to receive a third portion of the production stream from the well, wherein the multi-phase ejector is configured to induce the flow of the production stream from the well without decreasing an operating pressure of the high pressure production trap, thereby avoiding increasing a load to a flare in the gas-oil separation plant.
