Patent number: 9151856Abstract: A method for processing seismic data. The method may include receiving seismic data due to a plurality of seismic sources and applying a first operator to the seismic data to generate a first estimate of seismic data. The method may then include applying a second operator to the first estimate of seismic data to generate residual seismic data due to one or more seismic sources.

Patent number: 8588025Abstract: A technique for acquiring wide azimuth seismic data using simultaneous shooting is presented in which a plurality of seismic sources are positioned to achieve a desired crossline sampling as a function of the number of passes. This is accomplished by “interleaving” sources as deployed in the spread, as positioned in multiple passes, or some combination of these things, to achieve an effective shotline interval during acquisition or an effective crossline sampling less than their crossline source separation.Type: GrantFiled: December 30, 2009Date of Patent: November 19, 2013Assignee: WesternGeco L.L.C.Inventors: Nicolae Moldoveanu, Craig J.

Patent number: 8395966Abstract: A technique includes obtaining seismic data acquired by seismic sensors of a composite seismic signal that is produced by the firings of multiple seismic sources. The technique includes modeling the seismic data as being a function of models for the sources and linear operators and defining desired constraints on the models. The technique includes simultaneously determining the models based on the modeling and the desired constraints. The datasets are generated based on the determined models. Each dataset is indicative of a component of the composite seismic signal and is attributable to a different one of the seismic sources.Type: GrantFiled: April 24, 2009Date of Patent: March 12, 2013Assignee: WesternGeco L.L.C.Inventors: Ian Moore, Craig J.

Patent number: 8218393Abstract: A system includes an interface and a processor. The interface receives seismic datasets, which are associated with multiple firings of a set of at least one seismic source. Each dataset is acquired by seismic sensors during a different time period of a sequence of time periods that are limited by times at which the set of seismic source(s) are fired. The processor, for each of the firings of the set of seismic source(s), generates an associated shot record based on information contained at least two of the datasets.Type: GrantFiled: June 30, 2008Date of Patent: July 10, 2012Assignee: WesternGeco L.L.C.Inventor: Craig J.

Publication number: 20120155218Abstract: A method for processing seismic data. The method may include receiving seismic data due to a plurality of seismic sources and applying a first operator to the seismic data in an ith domain to generate a first estimate of seismic data due to an ith seismic source. The ith domain may correspond to the ith seismic source of the plurality of seismic sources. The method may then include applying a second operator to the first estimate of seismic data due to the ith seismic source in one or more domains other than the ith domain to generate residual seismic data due to one or more seismic sources other than the ith seismic source. After applying the a second operator to the first estimate of seismic data due to the ith seismic source, the method may determine a second estimate of seismic data due to the ith seismic source based on the first estimate and the residual seismic data due to the seismic sources other than the ith seismic source. The method may then repeat some of the steps described above (i.e.Type: ApplicationFiled: May 19, 2011Publication date: June 21, 2012Inventors: Craig J. Beasley, William H.

Patent number: 8174928Abstract: To reduce a number of required channels for a survey system having seismic sensors, the seismic sensors are partitioned into groups of corresponding seismic sensors. An aggregation unit applies different transformations of signals of the seismic sensors within a particular one of the groups. The differently transformed signals within the particular group are aggregated to form an aggregated signal. The aggregated signal for the particular group is transmitted, over a channel of the survey system, to a processing system.Type: GrantFiled: August 18, 2008Date of Patent: May 8, 2012Assignee: WesternGeco L.L.C.Inventor: Craig J.
