Interbed Multiple Elimination (IME)

IME is a layer related data-driven 2D and 3D interbed multiple model prediction and subtraction method based on a methodology extended from SRME (Jacubowicz, 1998). 

The user must identify a single interbed generator or generating zone and properly mute the input data to create 2 parts: the wave field generated by the multiple generator layer, and the wave field generated below this layer. In practice, the user can pick a pseudo boundary on a stack section, and mute the data along NMO curve.

Interbed Multiple Attenuation

• Interbed multiple attenuation at TGS is based on the approach of Jakubowicz.
• Knowledge of internal multiple generator is required
• Perform convolution of SR’ and S’R
• Cross correlate with S’R’ to separate SR internal multiple
• Adaptive subtraction of IME model
