Abstract
Seismic processing on cross-spread gathers is a valuable but underexploited strategy. To do it properly, sources from a single source line and receivers from a single receiver line must be ordered in a physically sensible way, so that adjacent sources or receivers on a surface diagram are physically near each other. But determining such an ordering is a challenge on irregularly acquired land data. I propose novel automatic ordering algorithms using tools from graph theory that minimize large gaps and preserve the sequential patterns found even in highly irregular acquisition. Java source code is available.
期刊介绍:
Geophysics, published by the Society of Exploration Geophysicists since 1936, is an archival journal encompassing all aspects of research, exploration, and education in applied geophysics.
Geophysics articles, generally more than 275 per year in six issues, cover the entire spectrum of geophysical methods, including seismology, potential fields, electromagnetics, and borehole measurements. Geophysics, a bimonthly, provides theoretical and mathematical tools needed to reproduce depicted work, encouraging further development and research.
Geophysics papers, drawn from industry and academia, undergo a rigorous peer-review process to validate the described methods and conclusions and ensure the highest editorial and production quality. Geophysics editors strongly encourage the use of real data, including actual case histories, to highlight current technology and tutorials to stimulate ideas. Some issues feature a section of solicited papers on a particular subject of current interest. Recent special sections focused on seismic anisotropy, subsalt exploration and development, and microseismic monitoring.
The PDF format of each Geophysics paper is the official version of record.
