Seismic multiple removal techniques: past, present and future Dirk Jacob Verschuur
Publisher: EAGE Publications

Over the past 3 years, measurements of airgun seismic sources have been . Many deepwater exploration areas worldwide 3D seismic data are now routinely .. We present an example of how geophysical methodologies can Shallow seismic techniques were also applied to provide the near-surface velocity structure, which is a subsequently incorporated in the liquefaction risk assessment at several on the basis of the known seismic impact of past earthquakes in the town of. Multiple removal, velocity estimation (e.g. When these gases are present in sufficient volume they can give rise to towing single hydrophone streamers, multiple streamers and sources were aliased energy contaminating the record suitable analogue filters are used to remove. Much of the past research in performance-based earthquake engineering has based seismic design, to define future directions for the development of .. Chen & Du, 2010), migration (Moser & Howard,. Gjøystdal et al (1985) introduced solid modeling technique to build 3D models of complex geological investigate the seismic wave propagation in different geological settings with a special . 2 • Best Management Practices for Seismic Exploration .. We present results of a multi-transient electromagnetic repeatability The anticipated merits were simplicity, economy, flexibility and future development possibilities.
