Beatty, J A; Berryman, J G

Accurate tomographic reconstructions of sound wave speed and attenuation are more difficult to obtain than are the corresponding reconstructions for x-rays or high frequency electromagnetic probes. The source of the difficulty is the common occurrence of large contrasts in acoustic or seismic wave speeds, leading to refraction and ray-bending effects. A new algorithm based on Fermat's principle has been developed to treat these problems. A description of the code STOMP (for Seismic TOMography Program) implementing the new algorithm is presented here together with a brief users manual for applications to borehole-to-borehole tomography. 3 refs., 3 figs.
