A METHOD FOR DETERMINING AND DISPLAYING THE SHEAR-VELOCITY REFLECTIVITIES OF A GEOLOGIC FORMATION Abstract In a method for determining and displaying the shear-velocity reflectivities of a geologic formation, a compression-wave common- depth-point seismic-data-gathering technique is utilized to produce both normal incidence compressional-velocity reflectivity sections and shear-velocity reflectivity sections for reflection points in the formation. The common-depth-point information is gathered for a plurality of incidence angles, (theta), of less than 20-30° such that assumptions concerning various elastic parameters, density, compressional-wave-velocity and shear-wave-velocity can be made which allow the application of linear fitting techniques to the gathered data. Estimates are then made of the coefficients (Rpp,0 and Rpp,1) of a linear function fitted to the amplitudes vs. sin2 (theta) measured for each point of reflection. The sum of these coefficients corresponds to the shear-velocity reflectivity of the reflection point and may be presented with similar data for other points in appropriate shear-reflectivity sections.
