Abstract

A seismic interval velocity study was carried out in the central part of Vancouver Island Line No.1. of the LITHOPROBE project. Independently of other methods, the study concentrated on a more accurate estimation of the "high velocity region'. The main point of the study was to carry out a series of high precision stacking velocity analyses along the line (including several neighbouring CDPs, similarly to applying "vertical stacking' prior to velocity analysis), by taking into consideration the dips and curvatures observable on the time section. In spite of the relatively small normal moveouts, the interval velocities could be estimated with appropriate accuracy if 50-150 neighbouring CDPs were considered simultaneously. -from Authors
