Abstract

Methods and systems of hydrocarbon production where wellbore stimulation and production is achieved in a single wellbore run-in, and inflow control devices are installed in an existing wellbore completion. A coiled tubing string is conveyed into a substantially horizontal portion of a wellbore, where the coiled tubing string has a production tubular configured to execute both stimulation and recovery operations. The production tubular can include an inflow control device to be installed in an existing wellbore.

Claims (43)

1. A method for producing fluids from an existing wellbore, comprising:

conveying a coiled tubing string from a surface into an existing completion assembly disposed in the wellbore with a coiled tubing conveyor, wherein hydrocarbons are drawn from a hydrocarbon formation through the existing completion assembly to the surface before the coiled tubing string is conveyed into the existing completion assembly, wherein the coiled tubing string comprises a production tubular including an inflow control device coupled to a first end thereof such that the production tubular is disposed within a substantially horizontal portion of the existing wellbore, and wherein the production tubular comprises:

a base pipe including a plurality of axial spacer strips coupled to an outer surface thereof;

a sand control screen including wire windings disposed about the axial spacer strips such that a plurality of small slotted openings are defined between the wire windings; and

a plurality of orifices formed through the base pipe;

injecting a fracing fluid into the coiled tubing string with a first pump coupled to a second end of the coiled tubing string, whereby the fracing fluid flows out the production tubular and into the hydrocarbon formation;

decoupling the first pump from the second end of the coiled tubing string and coupling the second end of the coiled tubing string to a second pump; and

drawing additional hydrocarbons from the hydrocarbon formation through the production tubular to the surface with the second pump, wherein the coiled tubing string is run into the wellbore a single time.

2. The method of claim 1 , wherein the hydrocarbon formation is fraced a first time before the coiled tubing string is conveyed into the existing completion assembly, and wherein injecting the fracing fluid further comprises fracing the hydrocarbon formation a second time.

3. The method of claim 1 , wherein the production tubular including the inflow control device is conveyed into the existing completion assembly without re-completing the wellbore.

4. The method of claim 1 , wherein the fracing fluid comprises water, acid, gel, foam, or combinations thereof.

5. The method of claim 1 , wherein the base pipe has an outer diameter between about 1 inch and about 3 inches.

6. A method for producing fluids from an existing wellbore, comprising:

conveying a coiled tubing string from a surface into an existing completion assembly disposed in the wellbore with a coiled tubing conveyor, wherein hydrocarbons are drawn from a hydrocarbon formation through the existing completion assembly to the surface before the coiled tubing string is conveyed into the existing completion assembly, wherein the coiled tubing string comprises a production tubular including an inflow control device coupled to a first end thereof such that the production tubular is disposed within a substantially horizontal portion of the existing wellbore, and wherein the production tubular comprises:

a base pipe including a plurality of axial spacer strips coupled to an outer surface thereof;

a sand control screen including wire windings disposed about the axial spacer strips such that a plurality of small slotted openings are defined between the wire windings; and

a plurality of orifices formed through the base pipe;

isolating first and second production zones of the hydrocarbon formation with a packer;

injecting a fracing fluid into the coiled tubing string with a first pump coupled to a second end of the coiled tubing string, whereby the fracing fluid flows out the production tubular and into the hydrocarbon formation;

decoupling the first pump from the second end of the coiled tubing string and coupling the second end of the coiled tubing string to a second pump;

drawing additional hydrocarbons from the hydrocarbon formation through the production tubular to the surface with the second pump, wherein the coiled tubing string is run into the wellbore a single time.

7. The method of claim 6 , wherein the hydrocarbon formation is fraced a first time before the coiled tubing string is conveyed into the existing completion assembly, and wherein injecting the fracing fluid further comprises fracing the hydrocarbon formation a second time.

8. The method of claim 6 , wherein the production tubular including the inflow control device is conveyed into the existing completion assembly without re-completing the wellbore.

9. The method of claim 6 , wherein the packer is disposed between the production tubular and the existing completion assembly.

10. The method of claim 6 , wherein the first and second production zones have different permeabilities.

11. The method of claim 10 , wherein the plurality of orifices are varied in density and size depending on the permeability of the first and second production zones.

12. The method of claim 6 , wherein the fracing fluid comprises water, acid, gel, foam, or combinations thereof.

13. A method for producing fluids from an existing wellbore, comprising:

conveying a coiled tubing string from a surface into an existing completion assembly disposed in the wellbore with a coiled tubing conveyor, wherein hydrocarbons are drawn from a hydrocarbon formation through the existing completion assembly to the surface before the coiled tubing string is conveyed into the existing completion assembly, wherein the coiled tubing string comprises a production tubular including an inflow control device coupled to a first end thereof such that the production tubular is disposed within a substantially horizontal portion of the existing wellbore, and wherein the production tubular comprises:

a base pipe including a plurality of axial spacer strips coupled to an outer surface thereof;

a sand control screen including wire windings disposed about the axial spacer strips such that a plurality of small slotted openings are defined between the wire windings; and

a plurality of orifices formed through the base pipe;

injecting a fracing fluid into the coiled tubing string with a first pump coupled to a second end of the coiled tubing string, whereby the fracing fluid flows out the production tubular and into the hydrocarbon formation;

decoupling the first pump from the second end of the coiled tubing string and coupling the second end of the coiled tubing string to a second pump;

drawing additional hydrocarbons from the hydrocarbon formation through the production tubular to the surface with the second pump, wherein the coiled tubing string is run into the wellbore a single time; and

creating a pressure drop in the production tubular with the plurality of orifices to normalize recovery of the additional hydrocarbons.

14. The method of claim 13 , wherein the hydrocarbon formation is fraced a first time before the coiled tubing string is conveyed into the existing completion assembly, and wherein injecting the fracing fluid further comprises fracing the hydrocarbon formation a second time.

15. The method of claim 13 , wherein the production tubular including the inflow control device is conveyed into the existing completion assembly without re-completing the wellbore.

16. The method of claim 13 , further comprising isolating first and second production zones of the hydrocarbon formation with a packer.

17. The method of claim 16 , wherein the packer is disposed between the production tubular and the existing completion assembly.

18. The method of claim 16 , wherein the first and second production zones have different permeabilities.

19. The method of claim 18 , wherein the plurality of orifices are varied in density and size depending on the permeability of the first and second production zones.

20. The method of claim 13 , wherein the tracing fluid comprises water, acid, gel, foam, or combinations thereof.
