Abstract:
1. A method comprising: performing forward modeling to compute a response of a target structure that includes a reflector, the forward modeling using reflection information relating to the reflector and accounting for distortion, caused by a wave associated with at least energy that travels parallel to the reflector, of a reflected signal reflected from the reflector, wherein performing the forward modeling comprises performing WKBJ (Wentzel, Kramer, Brillouin, and Jeffreys) forward modeling that accounts for the distortion caused by the wave associated with at least the energy that travels parallel to the reflector; and performing waveform inversion using the response of the WKBJ forward modeling and using each of pre-critical survey data, near-critical survey data, and post-critical survey data.
