A16 THE IMPACT OF FIELD SURVEY CHARACTERISTICS ON SURFACE-RELATED MULTIPLE ATTENUATION Summary 1 Three particular field survey characteristics – inline spatial sampling source stability and cable feathering – affect the quality of multiples predicted by surface-related multiple attenuation (SRME) algorithms. Careful survey design advanced data acquisition technologies and additional data processing steps can limit their impact. Introduction SRME is commonly practiced as a two-step process. First a multidimensional convolution-like iterative process predicts surface multiples using operators that consist of the recorded seismic traces themselves (Verschuur and Berkhout 1997). Second the predicted multiples are adaptively subtracted from the original traces. Under
