Seismic imaging framework

A system comprising:

• a processor;
• memory operatively coupled to the processor;
• and
• processor-executable instructions stored in the memory to instruct the system to:
• receive a seismic model for a geologic region, the seismic model includes an acoustic portion that accounts for wavefield kinematics using one or more acoustic velocity parameters and an elastic portion that accounts for wavefield elastic plane-wave reflectivity using one or more elastic vector reflectivity parameters;
• perform a wavefield simulation using the seismic model;
• during the wavefield simulation, determine angle dependent wavefield amplitude correction terms, subject to one or more structural dip-based angle criteria, using the elastic portion of the model;
• during the wavefield simulation, apply the angle dependent wavefield amplitude correction terms to wavefield amplitudes of the wavefield simulation to enhance seismic energy-based accuracy of the wavefield simulation;
• and
• generate a simulated wavefield as an output of the wavefield simulation.

One or more computer-readable storage media comprising computer-executable instructions executable to instruct a computing system to:

• receive a seismic model for a geologic region, the seismic model includes an acoustic portion that accounts for wavefield kinematics using one or more acoustic velocity parameters and an elastic portion that accounts for wavefield elastic plane-wave reflectivity using one or more elastic vector reflectivity parameters;
• perform a wavefield simulation using the seismic model;
• during the wavefield simulation, determine angle dependent wavefield amplitude correction terms, subject to one or more structural dip-based angle criteria, using the elastic portion of the model;
• during the wavefield simulation, apply the angle dependent wavefield amplitude correction terms to wavefield amplitudes of the wavefield simulation to enhance seismic energy-based accuracy of the wavefield simulation;
• and
• generate a simulated wavefield as an output of the wavefield simulation.
