Accurate seismic fault detection and fault surface extraction (or grouping) are critical aspects of reservoir characterization. This paper approaches fault tracking as an object detection and localization problem. The idea is to adopt a combination of morphological algorithms to pre-process data before tracking. Such operations result in the correction of breaks or imperfecttions in the fault structure. In addition, we employ connected-component analysis to identify connected regions in our binary fault map. Following that, each fault is labeled and tracked based on a specific metric. The fault surface is then constructed using the coordinates of a specific fault in the successive inline sections. This is accomplished by employing conventional surface fitting methods. Qualitative results indicate that the proposed tracking method is suitable for the construction of multiple fault surfaces at the same time.
