  • Device and method for deghosting seismic data using sparse tau-p inversion
    Patent number: 10345470
    Abstract: Computing device, computer instructions and method for improving accuracy of an image of a surveyed subsurface. The method includes a step of receiving seismic data (D) recorded with seismic sensors; a step of deghosting the seismic data (D) using a sparseT-Pinversion algorithm together with a low-rank optimization scheme and a high-cut filter to calculate ghost-free wave-fields (U0(t,x,y)) in the time-space domain; and a step of processing the ghost-free wave-fields (U0(t,x,y)) to generate the image of the surveyed subsurface.

  • METHODS AND DATA PROCESSING APPARATUS FOR COOPERATIVE DE-NOISING OF MULTI-SENSOR MARINE SEISMIC DATA
    Publication number: 20170097434
    Abstract: Method and data processing apparatus are used to process seismic data, including pressure data and sensor-acquired acceleration or sensor-acquired velocity data as acquired simultaneously by multi-component sensors in streamers. Equivalent acceleration data is obtained from the pressure data and used as references for de-noising the sensor-acquired acceleration data.
