The performance of various shaly sand satura- tion equations was compared to a Dual Water Model type saturation equation using practical examples of laminated sand-shales in the Gulf Coast. Equations evaluated included the Modified Simandoux equation of Bardon and Pied, the "Indonesia" equation of Poupon and Leveaux, and the simplified, laminated sand-shale relation of Poupon et al.
