Reuse is subject to Society of Exploration Geophysicists terms of use and conditions.Seismologists and geophysical literature often use the term “walkaway” to describe any survey used to analyze wavetrains based on source-to-receiver offset. A distinction should be made between receiver-group moveout (fixed-source walkaway) and source moveout (fixed-receiver walkaway) when multiple channels simultaneously record signal from multiple independent geophones. Three data sets are presented that illustrate this distinction: one collected in an area where a fixed-receiver walkaway survey recorded similar data and was more time efficient than a fixed-source walkaway survey, and two others collected in an area where dipping reflectors and laterally varying velocities caused the fixed-receiver walkaway data to be significantly different than the fixed-source walkaway data. The results show that, while still useful, clarity in recorded data is lost when fixed-receiver walkaway surveys are substituted for fixed-source walkaway surveys in areas with uneven surface topography, dipping interfaces, or laterally varying velocities. This is because walkaway seismograms are displayed by source-to-receiver offset, whereas neighboring traces do not correspond necessarily with neighboring raypaths or reflection points.Seismic wavesgeophysical techniquesgeophysical equipmentArticle10.1190/1.2337573openAccess
