Boosting production from low pressure or dead wells

1. A method for boosting or reviving production from a well connected to a gas-oil separation plant, the method comprising:

flowing a first portion of a processed crude oil stream from a pump in the gas-oil separation plant to a multi-phase ejector as motive fluid, wherein the processed crude oil stream flows to the multi-phase ejector at a first pressure, wherein the multi-phase ejector is in fluid communication with the well;

by the multi-phase ejector, converting pressure energy of the portion of the processed crude oil stream into kinetic energy, thereby reducing pressure within the multi-phase ejector and inducing flow of a production stream from the well to the multi-phase ejector as suction fluid, wherein a first portion of the production stream flows to the multi-phase ejector at a second pressure less than the first pressure, wherein the processed crude oil stream has a water content that is less than a water content of the production stream;

mixing, by the multi-phase ejector, the suction fluid and the motive fluid;

discharging, by the multi-phase ejector, the mixture of the suction fluid and the motive fluid at an intermediate pressure between the first pressure and the second pressure;

flowing the mixture of the suction fluid and the motive fluid at the intermediate pressure to a low pressure production trap in the gas-oil separation plant;

flowing a second portion of the processed crude oil stream from the pump to the low pressure production trap;

flowing a second portion of the production stream from the well to a high pressure production trap in the gas-oil separation plant; and

flowing a third portion of the production stream from the well to a high pressure test trap in the gas-oil separation plant, wherein production from the well connected to the gas-oil separation plant is boosted or revived without decreasing an operating pressure of the high pressure production trap, thereby avoiding increasing a load to a flare.

2. The method of claim 1 , wherein a remaining portion of the processed crude oil stream from the pump is flowed to the low pressure production trap.

3. The method of claim 2 , wherein the second pressure is at most 120 pounds per square inch gauge (psig).

4. The method of claim 3 , wherein the first pressure is at least 200 psig and up to about 250 psig.

5. The method of claim 4 , wherein the intermediate pressure is about 60 psig.

6. A method for reviving production from a dead well, the method comprising:

processing, by a gas-oil separation plant, crude oil to produce a processed crude oil stream;

flowing, by a pump in the gas-oil separation plant, a first portion of the processed crude oil stream to a multi-phase ejector as motive fluid, the multi-phase ejector in fluid communication with the well;

flowing, by the pump, a second portion of the processed crude oil stream to a low pressure production trap in the gas-oil separation plant; and

by the multi-phase ejector, converting pressure energy of the first portion of the processed crude oil stream into kinetic energy, thereby reducing pressure within the multi-phase ejector and reviving the dead well by inducing flow of a production stream from the dead well, wherein a first portion of the production stream flows to the multi-phase ejector as suction fluid, a second portion of the production stream flows to a high pressure production trap in the gas-oil separation plant, and a third portion of the production stream flows to a high pressure test trap in the gas-oil separation plant, wherein the processed crude oil stream has a water content that is less than a water content of the production stream, and flow of the production stream from the dead well is induced without decreasing an operating pressure of the high pressure production trap and does not result in increasing a load to a flare.

7. The method of claim 6 , wherein:

the low pressure production trap operates at about 50 pounds per square inch gauge (psig) or less;

the high pressure production trap operates at about 105 psig or less; and

the high pressure test trap operates at about 105 psig or less.

8. The method of claim 7 , wherein the processed crude oil stream is flowed by the pump at an operating pressure of about 210 psig or greater.

9. The method of claim 8 , wherein the induced flow of the production stream from the dead well has an operating pressure of about 110 psig or less.

10. The method of claim 9 , wherein the multi-phase ejector discharges a mixture of the first portion of the processed crude oil stream and the first portion of the production stream at an operating pressure in a range of from about 10 psig to about 110 psig.
