Abstract: A method includes receiving data representing measurements acquired by seismic sensors in response to energy that is produced by shots of a seismic source. The energy that is produced by the seismic source for each shot includes a plurality of discrete frequencies of discrete frequency bands that are within a frequency range of interest and are separated by at least one excluded frequency or frequency band. The data may be processed to determine at least one characteristic of a geologic structure.

Abstract: A technique facilitates obtaining seismic data in a marine environment. An array of acoustic sources is deployed in a marine environment. The array can be utilized for creating acoustic pulses that facilitate the collection of data on subsea structures. The methodology enables optimization of acoustic source array performance to improve the collection of useful data during a seismic survey.

Abstract: A marine survey acquisition system. The system may include a vessel for towing a marine survey spread. The marine survey spread may include streamers, marine vibrators and a cable. The cable may be coupled to a respective streamer from among the streamers and one of the marine vibrators. The cable may power the respective streamer and the one of the marine vibrators. The one of the marine vibrators may emit energy at a high frequency range.

Abstract: A technique includes towing at least one seismic source in connection with a survey of a structure; and operating the seismic source(s) to fire shots, where each shot is associated with a frequency sweep. The technique includes varying phases of the frequency sweeps from shot to shot according to a predetermined phase sequence to allow noise in an energy sensed by seismic sensors to be attenuated.
