Abstract
Wood's equation, originally proposed for uniform fluid suspensions, ca n describe the relationship of the compressional wave velocity, densit y, and the compressibility for high-porosity fine-grained sediments. W ood's equation predicts that these sediments can have compressional wa ve velocity lower than the overlying water. This acoustical behavior i s verified by showing that the minimum compressional wave velocity of these sediments predicted from Wood's equation is always less than or equal to the compressional wave velocity of water. Practical expressio ns are also derived for the fractional porosity of these sediments for which (I) the sediment compressional wave velocity becomes minimum an d (2) the sediment compressional wave velocity becomes the same as tha t of water.
