Abstract:
1. A method of identifying an internal multiple generator in a subterranean structure, comprising: injecting wavefields at plural levels in the subterranean structure, wherein the plural levels are proximate a predicted location of the internal multiple generator; recording wavefields induced by the injected wavefields, wherein the injecting and recording are simulated using a simulation system comprising a computer; and determining, by the simulation system comprising the computer, an effect of the internal multiple generator based on the recorded wavefields, wherein the internal multiple generator is represented by a first candidate horizon that indicates a first possible location of the internal multiple generator; repeating the injecting, recording, and determining for other candidate horizons that indicate other possible locations of the internal multiple generator; and comparing the determined effects for the corresponding candidate horizons and identifying one of the candidate horizons based on the comparing, the identified one candidate horizon representing a predicted location for the internal multiple generator.
