The Doukkala’s region is characterized by a sub-tabular scheme throughout, making difficult any conventional geological study based on outcrops. The use of three-dimensional models represents an interesting method to approximate the geometry and architecture of geological units. This study aims to monitor subsurface of the Cretaceous series, Miocene, and Pliocene-Quaternary and have a sufficient detailed level of knowledge of the different geological units of Doukkala. The current study uses data from 133 well drilled available in the SaDIN project database. The three-dimensional model is a source of geological information, a shared space of the basement data, and decision support tools; it will allow users to solve research problems or natural resource and hazards management.
