Building Constrained (3D) Geostatistical Models Case of the Triassic Sandstone Aquifer System (SE Tunisia)

Describing the distribution of aquifer units in 3 dimensions can be intricate especially in heterogeneous environments. In our case, the investigations of the Sahel el Abebsa area revealed a considerable thickness and facies variation within the Triassic Sandstone aquifer, likely related to the structural setup of the area. The primary objective of this work was therefore to provide a good 3D geometrical representation of the aquifer system honoring geology and available data.
