Abstract / Description of output

The development of Marchenko methods for seismic data has enabled the creation of an array of new imaging, redatuming, and multiple or primary estimation methods. Most of these methods make use of the subsurface up- and down-going Green's functions produced by the Marchenko scheme. However, equally important outputs are the so-called focusing functions. Here, we establish a novel interpretation of these focusing functions and use it to develop new methods to image the data. One of our methods can be used to image reflectors individually, which demonstrate on two experiments: a synthetic model and a field dataset from the North Sea. Our methods are computationally cheaper than standard Marchenko imaging and is shown to provide more continuous images with fewer artifacts than standard RTM. In addition they show the first individually imaged reflector using a Marchenko method on field data.
