  • Patent number: 10324210
    Abstract: A method comprising for deghosting seismic data is disclosed. The method includes the steps of acquiring seismic data by conducting a survey of a subsurface area of interest wherein the seismic data includes ghost data and estimating a time-varying wave height above the subsurface area of interest during at least a portion of the survey, wherein the estimation of the wave height is based at least in part on a remote measurement of the wave height during the survey. The estimated time-varying wave height is used to characterize the ghost data and deghost the seismic data based at least in part on the characterized ghost data.

  • Patent number: 9939543
    Abstract: Various implementations described herein are directed to methods for processing seismic data including enhancing seismic data generated by a seismic sensor. The methods may include receiving seismic data that had been acquired using the seismic sensor. The seismic data may include one or more first seismic data elements related to a first seismic event. The methods may include generating summands of the seismic data as an inner product of multiple seismic data elements associated with the first seismic data elements and one or more second seismic data elements. The second seismic data elements may be different than the first seismic data elements. The methods may further include enhancing the seismic data by estimating outliers in the summands of the inner product and replacing the outliers with interpolated values.
