In this work, we are concerned with the linear inverse problem associated to seismic imaging of subsurface geophysical structures between bore holes. More precisely, if we are given traveltime data as well as the rays paths between a set of sources and receptors suitably located in each well, how do we reconstruct the velocity profile? To solve such problem, we use techniques from linear algebra, optimization and numerical analysis. We provide a set of examples demostrating the efficiency of Algebraic Reconstruction Technique (ART) in the search of hydrocarbonet reservoirs.
