Abstract
Disclosed are various embodiments of methods for determining the velocity of seismic energy in geologic layers using Seismic Emission Tomography (SET) imaging of drill bit noise, by recording microseismic data during a drilling operation, recording the time and the position of a drill bit in a well bore during the drilling operation, processing the microseismic data using SET software to image microseismic events proximate a known time and position of the drill bit using an estimated velocity model, computing the difference between the known time and position of the drill bit and the time and position of the microseismic event determined from the SET data, varying the estimated velocity model to minimize the difference between the known time and position of the drill bit and the time and time and position of the microseismic event determined from the SET data.
