We present a workflow for doing automated salt interpretation by using a DNA-inspired search algorithm in combination with a quality based extrema surface extraction method. The DNA-search algorithm is used to map seismic patterns along top and base of the salt and the extrema method is used to connect and laterally extend the DNA-detected patterns into signal consistent extrema surfaces. The main objective with this workflow is to improve the quality of the salt interpretation and to make the interpretation process more efficient by replacing manual work with automation. The workflow has been demonstrated on a multi-client data set.
