In [[:file:dipmeters_fig3.png|Figure 3]], a raw dipmeter curve sharply distinguishes between sandstone and shale layers thinner than [[length::1 in.]] By establishing a cutoff line as shown, everything to the right can be identified as sand and everything to the left as shale. A reliable measurement of net sand thickness is thus provided, as well as the bulk volume fraction of shale in laminated form for input into laminated shaly sand saturation equations.
