Patent number: 11287543Abstract: A technique for use in geophysical surveying includes imparting a plurality of humming seismic signals and a plurality of low-frequency seismic signals into a geological formation. The technique also includes receiving returned seismic energy of the plurality of humming seismic signals and the plurality of low-frequency seismic signals after interacting with the geological formation and recording the returned seismic energy.Type: GrantFiled: May 9, 2018Date of Patent: March 29, 2022Assignee: BP CORPORATION NORTH AMERICA INC.Inventors: Andrew James Brenders, Joseph Anthony Dellinger, Graham Openshaw

Patent number: 10802167Abstract: The presently disclosed seismic acquisition technique employs a receiver array and a processing methodology that are designed to attenuate the naturally occurring seismic background noise recorded along with the seismic data during the acquisition. The approach leverages the knowledge that naturally occurring seismic background noise moves with a slower phase velocity than the seismic signals used for imaging and inversion and, in some embodiments, may arrive from particular preferred directions. The disclosed technique comprises two steps: 1) determining from the naturally occurring seismic background noise in the preliminary seismic data a range of phase velocities and amplitudes that contain primarily noise and the degree to which that noise needs to be attenuated, and 2) designing an acquisition and processing method to attenuate that noise relative to the desired signal.Type: GrantFiled: August 28, 2018Date of Patent: October 13, 2020Assignee: BP Corporation North America Inc.Inventors: Andrew James Brenders, Joseph Anthony Dellinger
