Abstract
A multi-shooting approach to seismic modeling and acquisition where several shot gathers can be generated simultaneously. The method is called a multi-shooting approach to seismic modeling and acquisition. A multi-shooting modeling method is disclosed which may be carried out on a computer system in either an explicit or an implicit manner. A multi-shooting acquisition method is also disclosed. The finite difference technique has the ability to generate elastic waves from several locations and at different time intervals simultaneously. The multi-shooting approach is based on the property of the finite difference technique. The decoding solution exploits the fact that specific time delays can be imposed between the various shots and that two closely space shooting points produce nearly identical responses.
