Eastern Tunisia is a semi-arid to arid area, located in the southern Mediterranean side, in North Africa. It is facing water scarcity, overexploitation, and decreasing water quality of the phreatic water table. Water supply and storage do not respond to the demographic and economic growth and demand. In addition, only 5 10⁹ m³ of water from 35 10⁹ m³ per year renewable rain water supply can be retained and remobilized as surface, dams, and groundwater resources. Geologic, seismic reflection, and wireline logging studies are carried out in order to investigate new deep reservoirs of semi-confined and confined aquifers. In this paper, we focused on the study of the Late Oligocene Rupelian-Early Miocene Aquitanian Fortuna sandstones, in the Sahel domain, because of their lack of studies and exploitation in these regions, despite their proven water reservoir potential elsewhere in Tunisia. They represent the semi-confined to confined aquifers. This study involves new seismic approach to highlight the hydrogeologic potential of these levels for their eventual exploitation in the future. Seismic reflection, sequence stratigraphy, tectonics, geology, and hydrogeology are integrated to highlight the identification and the structuring of these multi-layered extended sandstone reservoir horizons.

突尼斯东部是一个半干旱到干旱的地区，位于地中海南部，北非。它面临着水资源短缺、过度开发和潜水地下水位水质下降的问题。供水和储存不响应人口和经济增长和需求。此外，只有 5 10 ⁹ m ³的水来自 35 10 ⁹ m ³每年可再生的雨水供应可以作为地表、水坝和地下水资源保留和再利用。进行地质、地震反射和电缆测井研究，以调查半承压和承压含水层的新深层储层。在本文中，我们重点研究了萨赫勒地区晚渐新世 Rupelian-早中新世 Aquitanian Fortuna 砂岩，因为它们在这些地区缺乏研究和开发，尽管它们在突尼斯其他地方已被证明具有水藏潜力。它们代表半封闭到封闭含水层。这项研究涉及新的地震方法，以突出这些级别的水文地质潜力，以供将来最终开发使用。地震反射、层序地层学、构造学、地质学、
