Abstract

A battery of shock waves applicators positioned on a support beam having an elliptical or spherical shape in a common device wherein focused shock waves from the applicators combine to provide pseudo-planar waves over a far field distance.

Claims (22)

1. A shock wave device to provide acoustic pressure shock waves to a far field of an oil reservoir comprising:

a plurality of acoustic pressure shock wave reflectors having an elliptical shape configured to focus acoustic pressure shock waves produced by the shock wave device through a well bore casing and into the oil reservoir; and

a support beam having one of an elliptical or spherical shape coupled to and supporting the plurality of shock wave reflectors in an arrangement wherein focused shock waves produced by the plurality of shock wave reflectors combine to create pseudo planar focused acoustic pressure shock waves that reach far field beyond the well bore casing and into the oil reservoir.

2. The device of claim 1 , further comprising rollers coupled to the support beam.

3. The device of claim 2 , wherein the rollers are configured to provide one or both of longitudinal and rotational movement to the support beam.

4. The device of claim 3 , wherein the plurality of shock wave reflectors includes from three to thirty shock wave reflectors.

5. The device claim 4 , wherein the arrangement of the shock wave reflectors on the support beam is configured to direct the pseudo planar focused shock waves through perforations in the well bore casing.

6. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 5 .

7. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 4 .

8. The device claim 3 , wherein the arrangement of the shock wave reflectors on the support beam is configured to direct the pseudo planar focused shock waves through perforations in the well bore casing.

9. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 8 .

10. A method of delivering shock comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 3 .

11. The device claim 2 , wherein the arrangement of the shock wave reflectors on the support beam is configured to direct the pseudo planar focused shock waves through perforations in the well bore casing.

12. A method of delivering shock waves far comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 11 .

13. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 2 .

14. The device of claim 1 , wherein the plurality of shock wave reflectors includes from three to thirty shock wave reflectors.

15. The device claim 14 , wherein the arrangement of the shock wave reflectors on the support beam is configured to direct the pseudo planar focused shock waves through perforations in the well bore casing.

16. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 15 .

17. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 14 .

18. The device claim 1 , wherein the arrangement of the shock wave reflectors on the support beam is configured to direct the pseudo planar focused shock waves through perforations in the well bore casing.

19. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 18 .

20. A method of delivering shock waves comprising applying from between 300,000 to 5,000,000 shock wave shots with frequency ranging from 0.5 up to 10 HZ and with output energies in excess of 1 kJ up to 1 MJ to a location within the oil reservoir with the device of claim 1 .
