Abstract: There is a method for finding a best distribution of source elements that form a vibratory source array. The method includes inputting plural constraints for the source elements; generating plural distributions of the source elements that fulfill the plural constraints; calculating for each distribution a performance index characterizing the source array; and selecting the best distribution from the plural distributions based on a value of the performance index.

Abstract: Methods of compensating for source signature effects in seismic data are described. One method includes a step of receiving seismic data recorded with a receiver; a step of receiving source data of the seismic waves generated by the moving source; a step of receiving position data of the source while generating the seismic waves; a step of determining a transform operator using the source data, the position data, and a selected domain-transform operator; a step of determining a seismic model by mathematically optimizing a relationship between the transform and the seismic data; and a step of compensating for the source signature effects in the seismic data using the seismic model. A method for generating an image of a subsurface of a geographical area using seismic data includes compensating the seismic data for source signature effects using a model which assumes a moving, non-impulsive source.

Abstract: A resonant source element is configured to generate seismic waves in water. The resonant source element includes a housing having two openings covered by first and second pistons, wherein the first and second pistons are configured to freely translate relative to the housing to generate the seismic waves; and a high-pressure system configured to discharge inside the housing and to actuate the first and second pistons. The first and second pistons are configured to oscillate after the high-pressure system is fired to generate low-frequency seismic waves.
