Abstract
Transmission traveltimes in cross-well tomography are insufficient to determine the slowness field between the wells accurately. Horizontal smearing is common. In many cross-well data sets, traveltimes from reflections can also be picked. We study here the effect including these reflected traveltimes has on the resolution of the model. When reflected traveltimes are used, more unknown parameters need to be introduced to solve for the position of the reflectors. We compute the diagonal elements of the resolution matrix for two realistic cross-well geometries based on the McElroy field. We compare the resolution when no reflections are used, when reflections from only one side are used, and when reflections from both sides are used. Our results indicate that the reflector positions are very well determined, so these new unknowns can be determined from the new traveltime data. Including reflection traveltimes improves the resolution of the slowness field, particular near the reflectors.
