It may also depend on the way the shale is distributed in the formation. Shaly material can be distributed in the formation in three ways: Shale can exist in the form of laminae between which are layers of sand. Its shape is similar to a typical bell or box. It clearly indicates that Layer P 1 2 is a thick sandstone layer. Facies II shows a serrated shape in the gamma-ray logging curve over the whole of the reservoir, with teeth protruding in the middle of the box.
