Hamra Quartzite is one of the main reservoirs in the Algerian Saharan platform. It is characterized by variations in the thicknesses and geometry of the sandstone bodies, as well as the reservoir characteristics and types of fractures. Six natural fracture sets have been determined and have the same orientations as the seismic and sub-seismic faults. The maximum horizontal stress (SHmax) is homogeneous in the region and it is oriented NW-SE with a reorientation in some wells showing NE-SW to NNE-SSW orientation indicating a concordant scheme with a transcurrent dextral strike-slip fault. The various well tests carried out on Hamra Quartzite reveal the compact nature of this reservoir. Wells with hydrocarbon showings can be stimulated by targeting fracture swarms that are parallel to the maximum horizontal stress to improve the fluid flow rate.
