  • Methods, systems, and computer readable media for interactively determining parameters for ocean-bottom hydrophone/geophone receiver combination deghosting
    Patent number: 7450468
    Abstract: Methods, systems, and computer readable media are provided for interactively determining optimum deghosting parameter values for suppressing ghost reflections. Seismic data are obtained from various hydrophone/geophone receiver locations. Energy traces are generated which include measures of the deghosting parameter values from the seismic data obtained from each of the hydrophone/geophone receiver locations. The energy traces are displayed. A set of seed values is provided by the user. In response to receiving the user seed values, deghosting parameter values are picked based on the energy traces. The picked deghosting parameter values are displayed. A user then interactively edits and/or smooths the picks to obtain optimum deghosting parameter values. The optimum deghosting parameter values are utilized for suppressing ghost reflections in the seismic data.
