Abstract

Sand dune is known as sand grains and it is formed and accumulated by wind. Sand Dunes can be found in many regions such as Rubaii Alkhali in Saudi Arabia and sub-Sahara Africa. Distributed acoustic sensing (DAS) is a new technology that can be applied for detecting acoustic waves using a fiber-optic cable. The objectives of this study are to compare different methods of acquisitions in order to image the near surface covering with very loosy sand dunes. We used the conventional seismic acquisition method and DAS. In addition, we used in this test different kinds of DAS cables with different depths over the sand.
