Abstract: Methods and systems for survey operations are provided. In some embodiments, crossline measurement data measured by at least one survey receiver is received. Based at least in part on a characteristic of the crossline measurement data, an option from among a plurality of candidate options is selected, where the selected option is for use in an action relating to survey of a target structure.

Abstract: A technique includes determining an image of a subsurface geologic region of interest, where the image represents at least in part ghost energy that is attributable to reflections caused by a reflecting interface. The technique includes deghosting the image, which includes processing data representing the image in a processor-based machine to determine at least one impulse response of a modeling and migration of at least one point scatterer for the region and use the impulse response(s) to attenuate the ghost energy.
