Patent number: 10620329Abstract: A marine node for recording seismic waves underwater. The node includes a spherical body made of a material that has a density similar to a density of the water so that the body is buoyant neutral; a first sensor located in the body and configured to record three dimensional movements of the node; a second sensor located in the body and configured to record pressure waves propagating through the water; and one or more cables connected to the first and second sensors and configured to exit the body to be connected to an external device. The body is coupled to the water.Type: GrantFiled: October 31, 2012Date of Patent: April 14, 2020Assignee: Seabed Geosolutions B.V.Inventor: Philippe Herrmann

Patent number: 10101477Abstract: A system and method for performing seismic exploration with multiple acquisition systems is disclosed. The method includes configuring a first seismic source located outside of an exclusion zone and configuring a second seismic source located inside of the exclusion zone. The method further includes obtaining a first seismic dataset corresponding to a first seismic signal emitted by the first seismic source and obtaining a second seismic dataset corresponding to a second seismic signal emitted by the second seismic source. The method further includes combining the first and second datasets to create a complete dataset covering a survey area and creating a seismic image of a subsurface of the survey area.Type: GrantFiled: December 5, 2014Date of Patent: October 16, 2018Assignee: CGG SERVICES SASInventors: Cécile Berron, Philippe Herrmann, Julien Cotton, Eric Forgues, John J.

Patent number: 8743656Abstract: The invention relates to a method of seismic data processing, wherein the data includes a set of seismic traces, with each trace including a signal that has been recorded by a sensor after having been propagated in a subsurface area, with the signal being defined by an amplitude as a function of time, including the steps of: migration of data according to an initial time-velocity model, picking in the time-migrated data one or more event(s) corresponding to one or more subsurface reflector(s) so as to obtain facets locally approximating the event, kinematic demigration of the facets plotted so as to obtain simplified seismic data in the form of a set of facets and a set of attributes associated with the facets.Type: GrantFiled: May 30, 2008Date of Patent: June 3, 2014Assignee: CGG Veritas Services SAInventors: Philippe Herrmann, Gilles Lambare, Patrice Guillaume, Eric Suaudeau

Publication number: 20120213032Abstract: Apparatus, computer instructions and method for de-pegging seismic data related to a subsurface of a body of water. The method includes receiving as input recorded seismic data (H, G), wherein the recorded seismic data is recorded with a receiver having at least three components; extracting a three-dimensional (3D) gather from the recorded seismic data (H, G); separating up-going and down-going components (U, D) from the 3D gather using a 3D calibration operator (Gcal); and calculating de-pegged seismic data (P) based on the up-going and down-going components (U, D). The de-pegged seismic data (P) is calculated with no radon transform.Type: ApplicationFiled: February 16, 2012Publication date: August 23, 2012Applicant: CGGVERITAS SERVICES SAInventors: Philippe HERRMANN, Pierre HUGONNET
