  • Patent number: 8662243
    Abstract: The invention relates to a sweep-type vibratory seismic source where a baseplate is put to the ground and a series of impulses are applied through the baseplate into the ground and where the baseplate may periodically de-couple from the ground during the delivery of the impulses. A de-coupling baseplate tends to undertake a very high frequency flexing while high frequency energy is being delivered to the ground. The high frequency flexing may be picked up by the vibrator control system and interpreted as an unintended signal being delivered into the ground. While there are already issues getting high frequency data in the return wave field, allowing the vibrator electronics to alter the actual signal in a manner intended to squelch the high pitched ringing of the baseplate is apt to reduce the high frequency data in the data record. One solution for reducing the de-coupling and the ringing of the baseplate is a dampening pad positioned between the baseplate and the ground.

  • Patent number: 7284636
    Abstract: The present invention provides an accelerated weight drop for use as a seismic energy source, a method for operating an accelerated weight drop for use as a seismic energy source, and a seismic survey system including the accelerated weight drop. The accelerated weight drop, among other elements, may include a striker positionable over a surface, and a compressed gas spring configured to drive the striker toward the surface thus creating seismic waves within the surface. In this embodiment the striker is slidably coupled to the compressed gas spring.

  • Patent number: 6561310
    Abstract: A non-contact vibrometer is employed to measure seismic energy imparted to the earth by a land vibrator. The non-contact vibrometer can be a laser vibrometer operable to measure the motion of a baseplate of the land vibrator. A computing device can be used to record both the imparted seismic energy detected by the non-contact vibrometer and reflected seismic energy sensed with geophones.

  • Patent number: 6464035
    Abstract: Streamlined, towable, marine seismic energy vibrator for creating intense swept-frequency and pulse-coded seismic signals in a body of water has a sleek, fish-like configuration designed for towing with minimum drag. The vibrator has a streamlined hollow towing head and a streamlined hollow tail head mounted onto front and rear of a long cylindrical tubular wall which is modular, comprising cylinder sections joined in end-to-end axial alignment. Within this long tubular cylinder wall is an axially vibratable multi-piston assembly having a plurality of pistons on a long piston rod. One piston is positioned in each of the cylinder chambers. These chambers hive multiple ports opening out through the long cylindrical wall. An elongated circular cylindrical elastomeric bladder forms a water-filled bladder chamber encircling the wall.

  • Patent number: 6408978
    Abstract: A device for canceling non-acoustic self-noise associated with mechanically induced vibrations in sensor arrays and associated methods are described. The method utilizes the isolation of a vibration reference via digital beamforming to non-acoustic wavenumber space. This technique produces an interference reference measurement which is sensitive only to vibrations propagating within an array body and independent of acoustic signals propagating in surrounding medium.

  • Patent number: 6338394
    Abstract: Compact vibrator for emitting elastic waves in a material medium such as the subsoil. The vibrator comprises a baseplate (3) intended to be coupled in operation with a surface of this medium, an inertia mass (5) and at least a pair of electromechanical transducers (1, 2) comprising each one or more pillars (A, B) made for example of a piezoelectric or magnetostrictive material. Pillars (A) of first transducer (1) are interposed between baseplate (3) and a relay plate (4). Pillars (B) of the second transducer are interposed between relay plate (4) and inertia mass (5), on the same side of relay plate (4) as pillars (A) preferably, so that inertia mass (5) is positioned in the vicinity of baseplate (3), which contributes to the compactness and to the stability of the vibrator that can therefore be used on slightly sloping surfaces.

  • Patent number: 6119804
    Abstract: A dynamic force transducer for generating horizontally oriented shear forces and motion at a surface of a solid medium. A rigid frame is placed in direct contact with the surface of the solid medium. At least one pair of identical dynamic-force driver units is mounted on the frame to impart horizontally oriented forces to the frame. Symmetrical pairs of compliant springs support the force drivers, but the compliances of each pair of springs may be adjusted or interchanged with other similar springs to introduce different predetermined mechanical resonances. The driver units are excited to produce the horizontally oriented forces with one or more driver units imparting a pushing force and one or more driver units simultaneously imparting a pulling force.

  • Patent number: 6105712
    Abstract: Method for generating seismic intersection waves in an underground formation, wherein poles that are previously driven into the formation for other purposes or poles that are driven down for this purpose, said poles being used as a transfer medium for the intersection waves into the formation. The poles are put into transversal vibration by means of an oscillating mass, the oscillations being suitable for forming mainly horizontal polarized waves. In order to achieve a best possible impression of the formation, transversal waves may be generated in a first direction in a first period of time, and a second direction, different from the first direction, in a second period of time. Alternatively, the oscillating mass can be arranged to swing parallel to the pole in order to be able to generate pressure waves. The poles can be equipped with a "skirt", and/or with radially extending flanges in order to secure the best possible attachment in loose formations.

  • Patent number: 5969297
    Abstract: An apparatus for generating signals and energy for transmission to a large mass. The apparatus incorporates a pulsed generator such as a compensated pulsed alternator for storing and for discharging large amounts of energy in a controlled manner for transmission through a vibrator or similar electromechanical device. In the field of seismic exploration, the apparatus discharges seismic source energy into a land mass or water to generate seismic waves which are reflected from the interface between subsurface geologic formations. The pulsed generator permits the seismic source energy to be discharged in a controlled manner to shape the energy signal, and permits large quantities of energy to be discharged to increase the penetration depth and strength of the reflected signals.
