| Popis: | An empirical thickness versus time relationship sand curve has been established in the Rub’ al-Khali desert and verified by a theoretical curve from the direct measurements of sand. The empirical sand curve has variable success in other areas of Saudi Arabia. We established a theoretical sand curve model to determine the single-way time in dry sand. Tomographic modeling of a higher resolution 3D seismic survey contributes more data to refine the relationship. Polynomial curves were used in the calculation of near-surface static corrections to improve the solution for low-relief structures. |
