Study of Constrained Velocity Inversion of Seismic Data in North Sumatra Basin

Abstract

Constrained velocity inversion is an interval velocity analysis using an exponential asymptotically bounded velocity model, which can show a delineation match between the model and the velocity inversion functions. The constrained velocity inversion results were adequate for use as seismic velocity input data and produced a better seismic section than the root mean square velocity input data, indicated by clear continuity of the reflectors and the fault. Constrained velocity inversion applied to seismic data in the North Sumatra Basin showed a more rigorous seismic section compared to that from the root mean square velocity analysis.
