Patent number: 9316754Abstract: A seismic acquisition system includes a distributed optical sensor (having an optical fiber) and an interrogation subsystem configured to generate a light signal to emit into the optical fiber. The interrogation subsystem receives, from the distributed optical sensor, backscattered light responsive to the emitted light signal, wherein the backscattered light is affected by one or both of seismic signals reflected from a subterranean structure and noise. Output data corresponding to the backscattered light is provided to a processing subsystem to determine a characteristic of the subterranean structure.Type: GrantFiled: November 21, 2014Date of Patent: April 19, 2016Assignee: Schlumberger Technology CorporationInventors: Ed Kragh, Everhard Muyzert, Johan Robertsson, Douglas E.

Patent number: 8838392Abstract: Passive seismic data is collected from measurements of seismic sensors in respective sensor assemblies, where the passive seismic data is based on measurements collected during periods when no active seismic source was activated. Attenuation of surface noise in the passive seismic data is performed using data from divergence sensors in at least some of the sensor assemblies. The passive seismic data with surface noise attenuated is output to allow for performing an operation related to a subterranean structure using the passive seismic data with the surface noise attenuated.Type: GrantFiled: November 16, 2010Date of Patent: September 16, 2014Assignee: WesternGeco L.L.C.Inventors: David Fraser Halliday, Everhard Muyzert, Pascal Edme

Patent number: 8654606Abstract: A sensor assembly has first sensors spaced apart along a first direction, and second sensors oriented in a second direction generally orthogonal to the first direction. Differencing of outputs of the first sensors is performed, and differencing of outputs of the second sensors is performed. A signal output is produced by combining the differenced outputs of the first sensors and the differenced outputs of the second sensors, where the signal output represents a seismic response of a subterranean structure.Type: GrantFiled: July 27, 2010Date of Patent: February 18, 2014Assignee: WesternGeco L.L.C.Inventors: Everhard Muyzert, Pascal Edme, Julian Edward Kragh

Patent number: 8520469Abstract: A sensor assembly includes a housing structure, a seismic sensor in the housing structure to measure seismic waves propagated through a subterranean structure, and a pressure sensor in the housing structure. A processor in the housing structure is configured to receive a first signal based on an output of the seismic sensor, and a second signal based on an output of the pressure sensor. First and second digital filters are applied to the first and second signals. Application of the first and second digital filters to the first and second signals causes production of a substantially zero output in response to input that includes just noise data detected at the seismic sensor and the pressure sensor.Type: GrantFiled: April 9, 2010Date of Patent: August 27, 2013Assignee: WesternGeco L.L.C.Inventors: Daniel Ronnow, Qinglin Liu, Jon Magnus Soerli, Julian Edward Kragh, Pascal Edme, Everhard Muyzert
