Abstract: Methods and apparatuses for processing seismic data to generate images or determine properties of an interior section of the Earth. The seismic data is processed to filter coherent noise such as ground roll noise from seismic survey data. The noise is attenuated using 3D and/or 2D fan filters, which may have combined low-pass and band-pass filters derived from signal decomposition. The filters are designed with selected operator length, velocity bands of signals and noises and frequency range for a primary trace and adjacent traces within the operator length. The data is decomposed with the filters into signals and noises, and the noises are then filtered from the decomposed data. The process may be repeated for various frequencies and traces within the seismic data. The methods may be used for surveys that have either regular or irregular seismic receiver or seismic source positions.

Abstract: Separating survey data for multiple survey sources where first survey data along a first axis measured by a survey sensor device is received, the first survey data responsive to activations of the plurality of survey sources at respective azimuths with respect to the survey sensor device. Second survey data is rotated towards a first azimuth of a first of the plurality of survey sources. The rotated second survey data is used as a model of interference caused by a subset of the plurality of survey sources excluding the first survey source. In other examples, a time dithering technique is performed to separate survey data for multiple survey sources.
