  • Acoustic source assembly
    Patent number: 5652735
    Abstract: Acoustic source assembly for offshore seismic exploration, comprising at least one active vibration transducer (1) adapted to be excited by a sweep signal within a desired frequency range. At least one further and passive vibration transducer (2,3) is positioned at such small spacing (B) between the transducers that interaction therebetween provides for a relative enhancement of the frequency response of the whole source assembly at low frequencies.
    Type: Grant
    Filed: November 1, 1995
    Date of Patent: July 29, 1997

    Inventors: Svein Egil Johansen, Tor-Arvid Haugland, Thomas Clive Snook
  • Seismic sound source
    Patent number: 4775027
    Abstract: The volumetric capacity of the firing chamber of an air gun is discretely quantized by mounting unit-volume inserts interiorly of the firing chamber.
    Type: Grant
    Filed: November 18, 1987
    Date of Patent: October 4, 1988
    Assignee: Western Atlas International, Inc.
    Inventor: Tor-Arvid Haugland
  • Float arrangement
    Patent number: 4552086
    Abstract: The present invention relates to a float which is provided with at least one hoist drum for a hoisting wire from a hoist. The float is provided with at least one suspension drum for a suspension wire to a suspension body. The hoisting drum and the suspension drum are rotationally coupled to each other and the wires are arranged in such a way on the drums that the suspension wires are reeled in when the hoisting wires are reeled off the hoisting drums and vice versa.

  • Method of determining the signatures of arrays of marine seismic sources
    Patent number: 4476553
    Abstract: In order to determine the signature of an array of n seismic sources 21 to 27, for instance marine seismic sources in the form of air guns, the array is actuated and the emitted pressure wave is measured at n independent points whose positions will respect to the array are known by hydrophones 31 to 37. The measurements are processed to produce n equivalent signatures of the n sources taking into account the interactions therebetween. The signature of the array is then determined merely by superposing the n equivalent signatures.
