METHOD FOR MANAGING SHOTS IN A MULTI-VESSEL SEISMIC SYSTEM

Method for managing shots in a multi-vessel seismic system, comprising for each slave shooter vessel: a) computing a series of first theoretical shot times, as a function of a speed value of a scheduler shooter vessel and shot points associated to the scheduler shooter vessel, each first theoretical shot time being associated to one of the next shots of the scheduler shooter vessel; b) computing, as a function of a speed value of the slave shooter vessel and shot points associated to the slave shooter vessel, a series of second theoretical shot times each associated to one of the next shots of the slave shooter vessel; c) computing, as a function of the series of first theoretical shot times, a series of interpolated virtual shot times comprising at least the interpolated virtual shot times associated to the shots immediately before and after the next shots of the slave shooter vessel; d) computing, as a function of the series of first theoretical shot times, the series of interpolated virtual shot times and a minimum shot time interval, shooting time windows each associated to one of the next shots of the slave shooter vessel; e) for each next shot of the slave shooter vessel: if the associated second theoretical shot time is in the associated shooting time window, selecting as predicted shot time the associated second theoretical shot time; otherwise, selecting as predicted shot time the border of the associated shooting time window which is the closest from the associated second theoretical shot time.
