Patent number: 11604300Abstract: Systems and computer readable media are described that actuate at least one marine seismic source according to a constrained sequence. The sequence exhibits an actuation time or distance interval between each actuation. The actuation time or distance interval corresponds to the sum of a nominal time or distance and a respective dither time or dither distance for each actuation. The sequence is constrained such that differences between consecutive dither times or dither distances remain within a threshold dither difference. Constraining the sequence according to the threshold dither difference enables increased bottom speeds for the source (i.e., increased speeds of the source relative to the seafloor), while still maintaining at least a minimum actuation time or distance interval for the source, taking into account both the nominal time or distance and the respective dither times or dither differences.Type: GrantFiled: January 15, 2020Date of Patent: March 14, 2023Assignee: PGS Geophysical ASInventors: Manuel Beitz, Christian Strand, Rolf Huibert Baardman

Patent number: 11536867Abstract: Systems and methods include a method for deblending signal and noise data. A shot domain for actual sources, a receiver domain for virtual sources, and a receiver domain for actual sources are generated from blended shot data. A dictionary of signal atoms is generated. Each signal atom includes a small patch of seismic signal data gathered during a small time window using multiple neighboring traces. A dictionary of noise atoms is generated. Each noise atom includes a small patch of seismic noise data gathered during a small time window using multiple neighboring traces. A combined signal-and-noise dictionary is generated that contains the signal atoms and the noise atoms. A sparse reconstruction of receiver domain data is created from the combined signal-and-noise dictionary. The sparse reconstruction is split into deblended data and blending noise data based on atom usage to create deblended shot domain gathers for actual sources.Type: GrantFiled: July 31, 2019Date of Patent: December 27, 2022Assignee: Saudi Arabian Oil CompanyInventors: Robertus F. Hegge, Rolf Huibert Baardman

Patent number: 11422278Abstract: Computational systems and methods for randomizing the order in which multiple sources are fired in simultaneous source acquisition are described. In one aspect, pseudo-randomly shifted time delays are generated for each shot interval of a marine-survey-time line. Each shifted time delay is assigned to one or the sources. The sources within each shot interval are fired based on the shifted time delays.Type: GrantFiled: November 14, 2018Date of Patent: August 23, 2022Assignee: PGS Geophysical ASInventors: Roald Gunnar van Borselen, Rolf Huibert Baardman

Patent number: 10670757Abstract: This disclosure presents methods and systems for deblending blended seismic data obtained during simultaneous shooting acquisition into deblended seismic data gathers. Methods and systems iteratively separate the blended seismic data into the deblended seismic data gathers based on semblance analysis of a residual difference between the blended seismic data and the deblended seismic data gathers. Each deblended seismic data gather is associated with one of the sources and appears to have been obtained without substantial interference from seismic energy produced by other sources.Type: GrantFiled: April 29, 2014Date of Patent: June 2, 2020Assignee: PGS Geophysical ASInventor: Rolf Huibert Baardman

Publication number: 20200150303Abstract: A system for constraining a dither time can comprise a source and a controller coupled to the source. The controller can be configured to actuate the source in sequence, while the source is moving through a fluid volume at a bottom speed, with an actuation time interval between each actuation comprising a sum of a nominal time and a dither time for each actuation and constrain the dither time for each actuation such that a reduction of the actuation time interval relative to a directly precedent actuation time interval is at most a threshold dither time difference, wherein the threshold dither time difference corresponds to a maximum bottom speed.Type: ApplicationFiled: January 15, 2020Publication date: May 14, 2020Applicant: PGS Geophysical ASInventors: Manuel Beitz, Christian Strand, Rolf Huibert Baardman
