Abstract:
A method of attenuation of multiple reflections in seismic data, wherein the seismic data comprises pressure data and particle velocity data, the method comprising:deconvolving the seismic data in the plane wave domain; and applying a time signal moving average operator to the seismic data, using essentially the following formulae: P^&af;(Ï„i,p)=12&it;k&it;&Sum;j=i-ki+k&it;â€ƒ&it;P&af;(Ï„j,p)V^z&af;(Ï„i,p)=12&it;k&it;&Sum;j=i-ki+k&it;â€ƒ&it;Vz&af;(Ï„j,p).
