The Marchenko method allows seismic images to be constructed with reduced artifact contamination due to internal multiples. In this article we apply the method to a synthetic subsurface model containing vertical and horizontal features. We show that standard Marchenko methods fail to reconstruct wavefield components caused by vertical interfaces. We present a new way to incorporate VSP data into the Marchenko method that produces accurate subsurface images, even of vertical interfaces.
