..., and maintaining consistency between multiple well ties is difficult. We introduce an automatic approach to tying multiple wells that improves consistency among well ties. We first model synthetic seismograms for each well. We then create a synthetic image by interpolating the synthetic seismograms between...

.... In this paper we propose to employ both surface seismic and 3D VSP data simultaneously in one imaging process, such that – at least within an area around the well location – an optimum high-resolution image is obtained and the lateral continuity and consistency is guaranteed. Furthermore, by including all...
