A wavelet propagating in a finely layered lossless medium is subject to apparent attenuation that changes its shape. Can a sonic log be used to characterize this change? I show that numerical simulations with the well‐log as medium give an apparent attenuation or diffusion of the pulse that is very different from the attenuation in the real medium. This is due to the smoothing effect of the well‐log tool. Based on a version of the O’Doherty‐Anstey approximation, I derive an expression that… CONTINUE READING
