Patent number: 10001576Abstract: System and method for calculating a pre-plot for a marine seismic acquisition system. The method includes receiving as input a first number of streamer vessels and a second number of source vessels; receiving a geometry of an area to be surveyed; receiving a set of naturally different regions and/or humanly set targets for the area to be surveyed; calculating a first sailing path for a streamer vessel of the first number of streamer vessels; calculating a second sailing path for a source vessel of the second number of source vessels, based on the set of naturally different regions and/or humanly set targets; and entering the pre-plot into a navigation system of the streamer vessel and the source vessel so that the streamer and source vessels dynamically change an offset distance between them, while sailing during a seismic survey, based on the naturally different regions and/or humanly set targets.Type: GrantFiled: April 20, 2016Date of Patent: June 19, 2018Assignee: CGG SERVICES SASInventors: Damien Grenie, Risto Siliqi

Patent number: 9945973Abstract: Method and system for generating a full acquisition path for a marine seismic acquisition system. The method includes receiving survey area information about a survey area to be seismically surveyed; selecting a radius (R) and a length (L) of a lace; selecting an overlap distance (OL) between first and second lanes; generating the full acquisition path by repeating the lace along a first lead line inside the first lane and along a second lead line inside the second lane and replicating the first and second lanes until the entire survey area is covered with laces; and sending the full acquisition path to a streamer vessel for performing the seismic survey.Type: GrantFiled: July 5, 2016Date of Patent: April 17, 2018Assignee: CGG SERVICES SASInventors: Damien Grenie, Risto Siliqi, Julie Svay, Keith Wilhelm

Publication number: 20170363760Abstract: A multi-vessel seismic data acquisition system having a first vessel towing a streamer containing a plurality of seismic receivers and a pair of seismic sources along a first shot line. At least one additional vessel tows only a single seismic source. Each additional single seismic source is spaced from the pair of seismic sources an offset distance in at least one of an inline direction and a crossline direction to the first shot line to define a first bin grid having a first bin size for the first vessel and a second bin grid having a second bin size for each additional vessel.Type: ApplicationFiled: December 4, 2015Publication date: December 21, 2017Inventors: Thomas MENSCH, Damien GRENIE, Nicolas BOUSQUIE

Patent number: 9784864Abstract: Systems and methods for acquiring blended and unblended seismic data during a single seismic survey. The blended and unblended seismic data is generated with a plurality of sources that are fired in a dedicated sequence. The sequence involves firing all the sources at a first time, advancing the sources along a given path, firing only a first source at a second time, later than the first time, advancing the sources, firing again all the sources at a third time, later than the second time, advancing the sources, firing only a second source at a fourth time, later than the third time, and so on until a desired subsurface is fully surveyed.Type: GrantFiled: September 13, 2013Date of Patent: October 10, 2017Assignee: CGG SERVICES SASInventors: Damien Grenie, Thomas Mensch, Risto Siliqi

Patent number: 9746570Abstract: Presented are methods and a system for efficiently acquiring seismic data based on a virtual seismic spread. A streamer vessel and a source vessel are used in combination and in a specific spatial arrangement collect seismic data. The source arrays can be fired simultaneously, creating blended seismic data that is separated with a deblending algorithm or sequentially to collect seismic data directly. The virtual seismic spread can be configured to reduce survey time or decrease capital costs and health safety and environment exposure based on the size of the streamer array towed by the streamer vessel.Type: GrantFiled: June 6, 2014Date of Patent: August 29, 2017Assignee: CGG SERVICES SASInventors: Thomas Mensch, Damien Grenié, Risto Siliqi
