Short summary
This study characterizes the Tchirezrine II sandstone reservoir in northern Niger. Crucial for potential uranium in situ recovery (ISR), our multifaceted approach reveals (i) a network of homogeneously distributed orthogonal structures, (ii) the impact of clustered E–W fault structures on anisotropic fluid flow, and (iii) local changes in the matrix behaviour of the reservoir as a function of the density and nature of the deformation structure.
