“…The bonding process between source and receiver is called ray linking. For this study, the adopted methodology for the ray tracing is based in Schots (1990): the angle and the traveltime for each ray is calculated using the linking method, where the initial angle between source and receiver is a straight line in relation to the horizontal axis. If there is a strong variation in the slowness 100 SEISMIC TRAVELTIME TOMOGRAPHY IN THE DOM JOÃO FIELD, RECÔNCAVO BASIN, BRAZIL distribution, several rays may not reach the goal after an established number of iterations.…”

“…Several methods are described in the literature to determine the path described by the distance between two points. The following is the numerical algorithm described by Schots (1990). Applying the principle of Fermat in equation 22and knowing that the Euler equation is a necessary condition for the existence of an extreme value of the integral p2 p1 nds, we obtain the following differential equation for a heterogeneous environment:…”
