摘要： 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.

摘要： Controller and method for adapting a frequency sweep for a vibro-acoustic source element that is configured to generate acoustic waves during a seismic survey. The method includes driving a seismic source element to generate a current frequency sweep; recording seismic data with plural seismic sensors in response to the current frequency sweep; selecting, during the seismic survey, a data subset of the seismic data, wherein the data subset has a size less than 10% of the seismic data; calculating with a processing device an attribute based on the data subset; and calculating a new frequency sweep based on the attribute.

摘要： Computing device, system and method for calculating a far-field signature of a vibratory seismic source. The method includes determining an absolute acceleration of a piston of the vibratory seismic source while the vibratory seismic source generates a seismic wave; calculating, based on the absolute acceleration of the piston, a far-field waveform of the vibratory seismic source at a given point (O) away from the vibratory seismic source; and cross-correlating the far-field waveform with a driving pilot signal of the vibratory seismic source to determine the far-field signature of the vibratory seismic source.

摘要： 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.

摘要： Method, source array and seismic vibro-acoustic source element for seismic data acquisition. The method includes storing in a controller a library of beam form factor sets associated with a source array and corresponding regions to be surveyed; towing the source array along survey lines over the regions to be surveyed; selecting a beam form factor set from the library to be applied to the source array for each region; and actuating the source array based on the selected set of beam form factors and a position of the source array relative to the regions. Each set of beam form factors maps to a corresponding region of an area to be surveyed.
