  • Noise reduction in a particle motion sensing seismic streamer
    Patent number: 9759825
    Abstract: An apparatus includes particle motion sensors and a streamer that contains the particle motion sensors. The streamer is towed in connection with a seismic survey, and the towing of the streamer produces a turbulent flow. The streamer includes an inner cable and a fluid containing layer. The inner cable includes a material to circumscribe and extend along a longitudinal axis of the streamer and circumscribe at least one of the particle motion sensors. The fluid containing layer surrounds the inner cable to reduce noise that is otherwise sensed by the particle motion sensors due to the turbulent flow.

  • System and technique to suppress the acquisition of torque noise on a multi-component streamer
    Patent number: 8625389
    Abstract: A technique includes receiving particle motion data acquired by particle motion sensors while in tow. The particle motion data are indicative of a seismic signal and a torque noise, and the particle motion sensors are oriented to modulate a wavenumber of a first component of the torque noise away from a signal cone that is associated with the seismic signal. The technique includes estimating the first component of the torque noise and based at least in part on the estimated first component, estimating a second component of the torque noise inside the signal cone. The technique includes suppressing the second component of the torque noise based at least in part on the estimated second component.

  • Technique and system to cancel noise from measurements obtained from a multi-component streamer
    Patent number: 8593907
    Abstract: A technique includes receiving a pressure measurement and a particle motion measurement from at least towed seismic sensor. The pressure measurement contains signal and noise. The technique includes estimating the signal in the pressure measurement and based at least on the estimated signal in the pressure measurement, estimating a noise in the pressure measurement. Noise in the particle motion measurement is predicted based on at least the estimated noise in the pressure measurement, and the particle motion measurement is processed to remove noise based on at least the predicted noise.
