In this paper we introduce a Thalweg tracker as a new tool for tracking channels and associated margins. A Thalweg tracker is a voxel-based auto-tracking algorithm in which geobodies are allowed to grow in a user-controlled way. Unlike conventional voxel-based methods controlled primarily by amplitude thresholds, the growth can be adjusted to preferentially follow channel features and then build out the associated margins. In this paper we explain how the algorithm exploits the amplitude organization of channel features about 3D local maxima and minima and we show examples from three different basins.
