Silty clayey laminated, Mica-rich and Clay-rich mudstone lithofacies are the main lithofacies of Qusaiba Shale. Three pore groups have been identified in QS; inorganic-related pores, organic-related pores, and microfracture-related pores. The highest T1 value corresponding to the clay-rich mudstone lithofacies and the lowest value corresponding to silty-clayey laminated lithofacies. The T2 relaxation times of the studied samples correspond to between 1.1 and 2.8 p.u.
