  • Unayzah Formation is one of the most important exploration target in Rub Al Khali Basin Saudi Arabia. The depositional facies analysis based on the studies of field investigation and well cores and thin section research shows the dune, seasonal river, playa and paleosol environments. The rocks are mainly quartzite which has the high porosity and fair permeability. The sandstone diagenesis of Unayzah Formation has experienced the mechanic infiltration, concreation, dissolution, cementation and compaction. The diagenesis has relatively less influenced the quality of sandstone reservoirs because of the weak compaction and cementation. The pore types are mainly intergranular pores maintainning the good reservoir space.

Abstract: Unayzah Formation is one of the most important exploration target in Rub Al Khali Basin Saudi Arabia. The depositional facies analysis based on the studies of field investigation and well cores and thin section research shows the dune, seasonal river, playa and paleosol environments. The rocks are mainly quartzite which has the high porosity and fair permeability. The sandstone diagenesis of Unayzah Formation has experienced the mechanic infiltration, concreation, dissolution, cementation and compaction. The diagenesis has relatively less influenced the quality of sandstone reservoirs because of the weak compaction and cementation. The pore types are mainly intergranular pores maintainning the good reservoir space.
