Non-constant spatial parameters and/or temporal parameters are assigned respectively to at least one input shots sequence and shots time predictions computed from the input shots sequence, resulting in an adapted shots sequence. The spatial parameter may be a relative offset assigned to a shot, or a relative offset associated with a bearing. The temporal parameter may be a shot time interval. The parameters may be generated before the survey, at line submission and/or during the survey taking account of characteristics of the survey including ground and water properties, geometry of the shooting vessels, sea floor definition and specified depth observation. The adapted shots sequence provides flexibility for how and where to shoot during a multi-source marine seismic survey. |
