Abstract

Here, we will present a set of tools that we find are very well suited to address this challenge. Through our beam migration approach, we are able to efficiently and accurately image large dataset very rapidly and accurately image with a large migration aperture and with a full dip-range. The beam migration process is separated into two main components: a dipscan process that is performed once for the whole survey and which output is then stored on disk for later use, second a fast migration step is carried out ‘on-demand’ or through multiple model iterations. With modern computer hardware this imaging step can be performed in almost real-time. We also present beam-based imaging techniques that allow for more rapid model building in salt-regions through the use of velocity discriminating filtering in the imaging process.
