  • Patent number: 9759827
    Abstract: Method for generating an excitation signal for a first vibratory seismic source so that the first vibratory seismic source is driven with no listening time. The method includes a step of determining a first target spectrum for the first vibratory seismic source; a step of setting a first group of constraints for the first vibratory seismic source; and a step of generating a first excitation signal for the first vibratory seismic source based on the first group of constraints and the first target spectrum. The first seismic traces recorded with plural receivers can be identified when the first vibratory seismic source is driven with no listening time, based on the first excitation signal.

  • Publication number: 20170082764
    Abstract: A source controller distributed system for a multi-element marine source includes a master controller communicating via a cable with source controllers associated with source elements. The master controller generates commands for the source controllers. Each source controller is attached to sensors and mechanisms of one of the source elements, and controls the source element according to the received commands. The source controller also sends data to the master controllers, with the data being gathered by sensors of the source element and/or being related to the status of the source elements, alerts, and/or functional quality control.
