Seismic Systems and Methods Employing Repeatability Shot Indicators

摘要

Methods and systems for generating multi-criteria shot indicators are described. The multi-criteria shot indicator values can be weighted and the weighting factors can themselves incorporate one or more sensitivity factors. In another aspect, the shot indicators are related to the 4D repeatability and/or the 3D stability of seismic features associated with individual shots or sets of shots. The multi-criteria shot indicators can be evaluated in real-time onboard a seismic vessel and included as part of an infill reshoot decision making/ quality control process.
