Abstract: A seismic source array includes a first source and a second source. The first source has a first spectral output and the second source has a second spectral output different than the first spectral output. The first source has a first total volume different than a second total volume of the second source.

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 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: To acquire near-zero offset survey data, a survey source and a first streamer attached to the survey source are provided, where the first streamer has at least one survey receiver. A second streamer separate from the survey source and the first streamer includes survey receivers. Near-zero offset data is measured using the at least one survey receiver of the first streamer.
