System and method for marine seismic modeling

A computer system, comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions that when executed by the one or more processors cause the system to:
• a. receive, at a computer processor, a 4D water velocity library and a marine seismic survey geometry;
• b. create, via the computer processor, a full survey 3D earth model for each seismic shot time based on the 4D water velocity library to generate a set of dynamic 3D earth models;
• c. simulate 4D seismic shots for the set of dynamic 3D Earth models by simulating multiple shots on each node to generate a set of 4D seismic shot gathers;
• and
• d. output the 4D seismic shot gathers.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with one or more processors and memory, cause the device to

• a. receive, at a computer processor, a 4D water velocity library and a marine seismic survey geometry;
• b. create, via the computer processor, a full survey 3D Earth model for each seismic shot time based on the 4D water velocity library to generate a set of dynamic 3D Earth models;
• c. simulate 4D seismic shots for the set of dynamic 3D earth models by simulating multiple shots on each node to generate a set of 4D seismic shot gathers;
• and
• d. output the 4D seismic shot gathers.
