METHOD FOR ATTENUATING MULTIPLES

摘要

One embodiment of the present disclosure includes a method for processing seismic data comprising the steps of receiving data representing seismic energy gathered from a formation by a plurality of seismic receivers, wherein the data include primary and multiple data. A copy of the received data is created and compensated to reduce amplitude attenuation effects due to transmission and absorption losses. A multiple prediction algorithm is applied to the received and compensated data to obtain a multiple data prediction. The multiple data prediction is subtracted from the received data to obtain primary data. The primary data is processed to reduce attenuation effects in the received data.

1. A method for processing seismic data comprising the steps of:
receiving data representing seismic energy gathered from a formation by a plurality of seismic receivers, wherein the data include primary and multiple data; creating a copy of the received data; compensating the copied data to reduce amplitude attenuation effects due to transmission and absorption losses; applying a multiple prediction algorithm to the received and compensated data to predict the multiple data; subtracting the predicted multiple data from the received data and obtain the primary data; and processing the primary data in the received data to reduce attenuation effects.
