Abstract
The aim of this study is to test a new seismic interpretation workflow based on high- definition seismic attributes, by evaluating its efficiency in identifying and mapping dolomite bodies and dolomitization fronts. Recently shot 3D seismic data from the Arabian Basin, onshore Saudi Arabia have been chosen for evaluating the workflow, since they cover a rock volume that exhibits extensive dolomitization containing dolomite bodies more than 300 m thick. The seismic interpretation has been calibrated with well-log and core data, to ensure that the results are geologically plausible. The results of the new high-definition workflow have also been benchmarked with conventional seismic attributes, such as RMS amplitudes, to evaluate the efficiency and level of detail provided by the new approach
