Abstract
B040 Adaptive Multiple Subtraction in the 2D Wavelet Transform Domain I. Ahmed* (BP) K.H. Matson (BP) & Z. Yu (BP) SUMMARY In SRME the multiples are predicted by convolving the data by itself. It is a common practice in the industry to use Least-Squares adaptive subtraction in the space-time domain to match the predicted multiples to the multiples in the data. The existing Least-Squares adaptive subtraction in the space-time domain though quite robust does have some limitations. This paper will try to address some of those limitations by doing the Least-Squares adaptive subtraction in the 2D Wavelet-Transform domain. EAGE 69
