Generating synthetic seismograms by convolving wavelets with reflection coefficients to simulate seismic responses
Detailed Documentation
Synthetic seismograms provide crucial information about Earth's crustal structures and oil field exploration. This methodology involves convolving seismic wavelets with reflection coefficients to simulate how seismic waves interact with subsurface geological interfaces. These simulated records enable geophysicists to infer underground structures through forward modeling techniques. The implementation typically involves defining a source wavelet (e.g., Ricker wavelet), calculating reflection coefficients from impedance contrasts, and performing time-domain convolution. For example, in MATLAB this can be achieved using:
reflectivity = calculate_reflection_coefficients(impedance_model); synthetic_trace = conv(source_wavelet, reflectivity, 'same');Seismologists and geologists rely on these synthetic records as essential tools for validating seismic interpretations and advancing knowledge of Earth's interior. By leveraging these synthetic seismograms, researchers can enhance understanding of crustal architecture, potentially leading to new hydrocarbon discoveries and optimized extraction strategies.
