ABSTRACT A method is disclosed for obtaining an estimate of the shear velocity in a formation material. Utilizing compressional velocity (Vp) and density (p) of the forma- tion material, formation aggregate mineral parameters and formation pore fluid parameters together with a relation- ship that the frame bulk modulus/frame shear modulus is approximately equal to the bulk modulus of the aggregate mineral grains/shear modulus of the aggregate mineral grains, to obtain an estimate of the shear wave velocity (Vs) of the formation material. The present invention is primarily designed for use in the areas where shear wave velocity (Vs) measurements are unobtainable due to uncon- solidated formations, and specifically, wherein the acous- tic velocity of formation fluids and/or wellbore fluids is greater than the desired shear wave velocity.
