Abstract
Method for updating a velocity model () for migrating seismic data using migration velocity scans with the objective of building a model that reproduces the same travel times that produced selected optimal images from a scan. For each optimal pick location () in the corresponding test velocity model (), a corresponding location is determined () in the velocity model to be updated, using a criterion that the travel time to the surface for a zero offset ray () should be the same. Imaging travel times are then computed from the determined location to various surface locations in the update model (), and those times are compared to travel times in the test velocity model from the optimal pick location to the same array of surface locations. The updating process consists of adjusting the model to minimize the travel time differences ().
