Abstract
The standard requirement for up-down wavefield separation in seismic data is to use multi-component data. An important application for such separation is to remove the interference from multiple reflections from either the free surface or the internal subsurface structures. As an alternative, we propose an automatic scheme of estimating the up-down wavefields in a horizontal borehole using only single component measurements. The scheme builds upon recent developments of the Marchenko method. The up-down fields are constructed essentially from the surface reflection response (surface seismic data), together with the direct waves' travel time from the borehole data. No prior information of the subsurface is needed, and an automatic working flow is suggested. The numerical test using a synthetic field model shows good results compared to that from a conventional multi-component approach.
