Patent number: 8958266Abstract: Described are methods for obtaining seismic signals representative of properties of the earth's interior, including the steps of obtaining near-field acoustic signals recorded in the vicinity of a seismic source (13), muting from the near-field acoustic signals at least partly signals representing direct arrivals from the seismic source (13), and using a remaining part of the obtained signals as estimate of a zero-offset data set. The zero-off set data set can then be used to interpolate data from conventional acquisition location, such as streamers (11), to locations closer to the source (13).Type: GrantFiled: August 13, 2007Date of Patent: February 17, 2015Assignee: Schlumberger Technology CorporationInventors: Julian Edward Kragh, Johan Olof Anders Robertsson, Everhard Johan Muyzert, Clement Kostov

Patent number: 7408836Abstract: A method of and apparatus for processing seismic data. A method of processing seismic data comprising the steps acquiring seismic data in at least two shots that have different source-receiver azimuths from one another, and selecting events arising from interface seismic waves in each shot. The interface wave events are processed to provide information about azimuthal dependence of the velocity of seismic energy in the near-surface of the earth's interior. The invention may be used to process events arising from Scholte waves in marine seismic data, or to processing events arising from Love waves or Rayleigh waves in land seismic data. The method may be applied to seismic data acquired specifically to provide information about the near-surface or to seismic data acquired to provide information about the underlying geological structure.Type: GrantFiled: December 19, 2002Date of Patent: August 5, 2008Assignee: Westerngeco L.L.C.Inventors: Everhard Johan Muyzert, Jan Henrik Kommedal
