Abstract

A method of servicing a wellbore, comprising transporting a fluid treatment system to a wellsite, accessing a water source proximate to the wellsite, introducing a water stream from the water source into the fluid treatment system, irradiating at least a portion of the water stream within the fluid treatment system, wherein the portion of the water stream is irradiated by exposing the portion of the water stream to ultraviolet light emitted from at least one pulsed ultraviolet lamp, forming a wellbore servicing fluid from the irradiated water stream, and placing the wellbore servicing fluid into the wellbore.

Claims

1. A method of servicing a wellbore, comprising:

transporting a fluid treatment system to a wellsite;

accessing a water source proximate to the wellsite;

introducing a water stream from the water source into the fluid treatment system;

irradiating at least a portion of the water stream within the fluid treatment system, wherein the portion of the water stream is irradiated by exposing the portion of the water stream to ultraviolet light emitted from at least one pulsed ultraviolet lamp;

forming a wellbore servicing fluid from the irradiated water stream; and

placing the wellbore servicing fluid into the wellbore.

2. The method of claim 1, wherein the fluid treatment system comprises an ultraviolet irradiation unit comprising at least one ultraviolet irradiation chamber.

3. The method of claim 2, wherein the at least one ultraviolet irradiation chamber comprises the at least one pulsed ultraviolet lamp.

4. The method of claim 3, wherein the at least one ultraviolet irradiation chamber comprises a first group of pulsed ultraviolet lamps and a second group of pulsed ultraviolet lamps, wherein the lamps of the first group of pulsed ultraviolet lamps and the lamps of the second group of pulsed ultraviolet lamps are positioned within the ultraviolet irradiation chamber about perpendicular to a flowpath of the water stream through the ultraviolet irradiation chamber.

5. The method of claim 4, wherein the first group of pulsed ultraviolet lamps is radially offset from the second group of pulsed ultraviolet lamps.

6. The method of claim 4, wherein the first group of pulsed ultraviolet lamps is axially offset from the second group of pulsed ultraviolet lamps.

7. The method of claim 3, wherein the at least one pulsed ultraviolet lamp is positioned within the ultraviolet irradiation chamber about parallel to a flowpath of the water stream through the ultraviolet irradiation chamber.

8. The method of claim 7, wherein the at least one pulsed ultraviolet lamp is positioned about in the center of the flowpath.

9. The method of claim 7, wherein the at least one pulsed ultraviolet lamp is offset from the center of the flowpath.

10. The method of claim 1, wherein irradiation of the water stream occurs at a rate that is at least 10% greater than a rate at which the water could be irradiated by exposing the portion of the water stream to ultraviolet light emitted from a continuous mercury vapor lamp so as to achieve an equivalent microorganism inactivation as in the irradiated stream.

11. The method of claim 1, wherein irradiation of the water stream occurs at a rate that is at least 20% greater than a rate at which the water could be irradiated by exposing the portion of the water stream to ultraviolet light emitted from a continuous mercury vapor lamp so as to achieve an equivalent microorganism inactivation as in the irradiated stream.

12. A method of servicing a wellbore, comprising:

accessing a water source to form a water stream;

irradiating at least a portion of the water stream to yield an irradiated water stream, wherein the portion of the water stream is irradiated by exposing the portion of the water stream to ultraviolet light emitted from a pulsed ultraviolet lamp;

forming a wellbore servicing fluid from the irradiated water stream; and

placing the wellbore servicing fluid into the wellbore.

13. The method of claim 12, further comprising measuring turbidity of the water stream, turbidity of the irradiated stream, or both.

14. The method of claim 13, further comprising controlling a rate at which the portion of the water stream is irradiated based on the turbidity of the water stream, the turbidity of the irradiated stream, or combinations thereof.

15. The method of claim 12, wherein irradiation of the water stream occurs at a rate that is at least 10% greater than a rate at which the water could be irradiated by exposing the portion of the water stream to ultraviolet light emitted from a continuous mercury vapor lamp so as to achieve an equivalent microorganism inactivation as in the irradiated stream.

16. The method of claim 12, wherein irradiation of the water stream occurs at a rate that is at least 20% greater than a rate at which the water could be irradiated by exposing the portion of the water stream to ultraviolet light emitted from a continuous mercury vapor lamp so as to achieve an equivalent microorganism inactivation as in the irradiated stream.

17. A fluid treatment system for servicing a wellbore, comprising:

an ultraviolet irradiation unit, the ultraviolet irradiation unit comprising at least one ultraviolet irradiation chamber, the at least one ultraviolet irradiation chamber comprising at least one pulsed ultraviolet lamp;

at least one component of wellbore servicing equipment, the ultraviolet irradiation unit being in fluid communication with the at least one component of wellbore servicing equipment; and

a wellhead providing access to the wellbore, the at least one component of wellbore servicing equipment being in fluid communication with the wellhead.

18. The system of claim 17, wherein the at least one ultraviolet irradiation chamber comprises a first group of pulsed ultraviolet lamps and a second group of pulsed ultraviolet lamps, wherein the lamps of the first group of pulsed ultraviolet lamps and the lamps of the second group of pulsed ultraviolet lamps are positioned within the ultraviolet irradiation chamber about perpendicular to a flowpath of the water stream through the ultraviolet irradiation chamber.

19. The system of claim 18, wherein the first group of pulsed ultraviolet lamps is radially offset from the second group of pulsed ultraviolet lamps.

20. The system of claim 18, wherein the first group of pulsed ultraviolet lamps is axially offset from the second group of pulsed ultraviolet lamps.

21. The system of claim 17, wherein the at least one pulsed ultraviolet lamp is positioned within the ultraviolet irradiation chamber about parallel to a flowpath of the water stream through the ultraviolet irradiation chamber.

22. The system of claim 21, wherein the at least one pulsed ultraviolet lamp is positioned about in the center of the flowpath.

23. The system of claim 21, wherein the at least one pulsed ultraviolet lamp is offset from the center of the flowpath.

24. The system of claim 17, wherein the at least one component of wellbore servicing equipment comprises a blender, a manifold, a high-pressure pump, or combinations thereof.
