The solution to seismic problems depends on the availability of detailed data on the elastic properties of the rocks in the survey area as they exist under natural conditions. It would be desirable to use equipment that records the wave response in the well to impulse excitation in analog form. Such a log would permit us not only to determine the corresponding physical properties of the rock with a high degree of accuracy and to make surface/inhole seismic surveys, but also to solve various problems in the propagation of ultrasonic waves in actual media, which might be important in classifying rock types according to combinations of physical properties.
