Crossline Reconstruction Using Aliased 3D Deghosted Up- and Downgoing Wavefields

This paper formulates a new model for crossline reconstruction that relies on aliased, 3D decomposed, up- and downgoing waves. It also presents a closed form approach to solve the joint reconstruction and 3D deghosting problem. The new model provides additional insight into how the ghost reflection and the vertical component of particle velocity/acceleration are exploited in crossline reconstruction and joint 3D deghosting solutions for towed streamer applications.
