Publication number: 20200333485Abstract: Processes and systems described herein are directed to performing marine surveys with a moving vibrational source that emits a continuous source wavefield into a body of water above a subterranean formation. The continuous source wavefield is formed from multiple sweeps in which each sweep is emitted from the moving vibrational source into the body of water with a randomized phase and/or with a randomized sweep duration. Reflections from the subterranean formation are continuously recorded in seismic data as the moving vibrational source travels above the subterranean formation. Processes and systems include iteratively deconvolving the source wavefield from the continuously recorded seismic data to obtain an earth response in the common receiver domain with little to no harmful effects from spatial aliasing and residual crosstalk noise. The earth response may be processed to generate an image of the subterranean formation.Type: ApplicationFiled: April 10, 2020Publication date: October 22, 2020Applicant: PGS GEOPHYSICAL ASInventors: Stian Hegna, Okwudili Orji, Mattias Oscarsson-Nagel

Patent number: 10393897Abstract: This disclosure is related to marine seismic sources, for example marine seismic sources known in the art as benders. Some embodiments of this disclosure use Lorentz forces to produce seismic energy. For example, magnets and wire coils may be attached to one or more plates of a marine seismic source, and the Lorentz interaction between them may cause deformation of the plates to produce seismic energy. Such marine seismic sources may be components of a marine seismic survey system, and may be used in a method of marine seismic surveying. Methods of making marine seismic sources are also disclosed.Type: GrantFiled: April 17, 2018Date of Patent: August 27, 2019Assignee: PGS Geophysical ASInventors: Mattias Oscarsson, Oeystein Traetten, Rune Voldsbekk, Rune Toennessen
