Claims
- 1. A seismic acquisition system comprising:
an energy source including a perforating shaped charge to generate a seismic signal; and a detector positioned to detect a reflected signal in response to a seismic wavefront.
- 2. The seismic acquisition system of claim 1, wherein the perforating shaped charge generates a perforating jet.
- 3. The seismic acquisition system of claim 2, wherein the seismic wavefront includes a pressure wave generated by the perforating jet.
- 4. The seismic acquisition system of claim 1, further comprising an anchor.
- 5. The seismic acquisition system of claim 4, wherein the perforating shaped charge includes a housing fixed with respect to the anchor.
- 6. The seismic acquisition system of claim 4, further comprising a ramming member to drive the anchor into a ground surface.
- 7. The seismic acquisition system of claim 6, wherein the ramming member includes a ramming pipe engageable by a ramming system.
- 8. The seismic acquisition system of claim 6, wherein the ramming member may be manually manipulated by a user.
- 9. The seismic acquisition system of claim 1, further comprising a detonator ballistically engaged to the perforating shaped charge.
- 10. The seismic acquisition system of claim 9, further comprising an electrical wire coupled to the detonator.
- 11. The seismic acquisition system of claim 1, further comprising at least another energy source.
- 12. The seismic acquisition system of claim 1, further comprising at least another detector.
- 13. The seismic acquisition system of claim 1, wherein the perforating shaped charge is positioned to direct the perforating jet into an earth sub-surface.
- 14. The system of claim 1, wherein the perforating shaped charge includes a liner that contributes to generation of the perforating jet.
- 15. The system of claim 14, wherein the liner is generally conically shaped.
- 16. The system of claim 14, wherein the liner is generally bowl-shaped.
- 17. The system of claim 1, wherein the perforating shaped charge includes a cavity containing an explosive that is un-lined.
- 18. A method of acquiring seismic data requesting a characteristic of an earth sub-surface, comprising:
positioning an energy source having a perforating shaped charge; and activating the perforating shaped charge to transmit a seismic signal into the earth sub-surface.
- 19. The method of claim 18, wherein activating the perforating shaped charge generates a perforating jet.
- 20. The method of claim 18, further comprising arranging plural energy sources each including the perforating shaped charge and activating the perforating shaped charges to create seismic signals.
- 21. An apparatus for use in a seismic acquisition system, comprising:
a perforating shaped charge positioned near an earth surface and activable to generate a seismic signal into an earth sub-surface.
- 22. The apparatus of claim 21, further comprising a detector to receive a signal reflected from the earth sub-surface in response to the seismic signal.
- 23. The apparatus of claim 21, further comprising plural perforating shaped charges arranged in a predetermined pattern.
