The region of Boudnib is located in southeast Morocco and depends on the territorial region of Draa-Tafilalet and the province of Errachidia. It has a water deficit due to the lack of rainfall in the region and the overexploitation of groundwater. 76 electrical drillings were drilled and correlated with borehole and seismic reflection data to understand and identify the structure and geometry of the deep aquifer to facilitate the selection of future boreholes and wells. The geophysical study allowed us to differentiate three families of electrical boreholes. These families are separated by two geoelectrical discontinuities D1 and D2. That of D1 coincides with the core of a ramp fold anticline, which affects the Tertiary and whose detachment plane is located above the Turonian roof. The conductive level B of the longitudinal conductor map C presents a good aquifer for the future exploitation of water it is rich in sands and the longitudinal conductance A1 which is located at the level of the family A represents a zone less favorable to the exploitation of water because it has important contents of clayey element.
