2D and 3D resistivity inversion of Schlumberger vertical electrical soundings in Wadi El Natrun, Egypt: A case study

► We applied 2D and 3D resistivity inversion codes on vertical electrical soundings. ► The code is based on the finite element technique and regularization method. ► The nature of the waterless area and non-productive wells is explained. ► The most promising high water productive zones were highlighted.
