Abstract: Apparatus, computer instructions and method for controlling an energy output of a source array to be used in a seismic survey for illuminating a subsurface. The method includes generating a model (β) based on up-going (U) and down-going (D) components of seismic waves generated by source elements that form the source array; calculating the amplitudes and phases of each source element based on the model (β); and driving the source array based on the calculated amplitudes and phases for the source elements so that a ghost generated by the source array is reduced at emission.

Abstract: The present disclosure includes a method for reducing noise in seismic data using a frequency dependent calendar filter. The method for reducing noise in input seismic trace data includes obtaining a plurality of input seismic trace data, the plurality of input seismic trace data including a plurality of controlled signals and a plurality of uncontrolled signals, identifying a frequency content of the plurality of uncontrolled signals, and selecting a frequency dependent calendar filter based on the frequency content of the plurality of uncontrolled signals. The method further includes applying the frequency dependent calendar filter to the plurality of input seismic data to generate a plurality of output noise-reduced seismic traces. The present disclosure also includes associated systems and apparatuses.

Abstract: A system and method for correcting data after component replacement in continuous seismic exploration disclosed. The method includes calculating a first matching operator after a first component is replaced with a second component. The first matching operator is based on a first seismic trace recorded before replacement of the first component and a second seismic trace recorded after replacement of the first component. The method further includes correcting the second seismic trace by applying the first matching operator to the second seismic trace.
