Seismic Model Parameter Estimation Using Least-Squares Migration

P016 Seismic model parameter estimation using least-squares migration Abstract 1 We describe a method for verifying seismic modelling parameters. It is equivalent to performing several iterations of unconstrained least-squares migration (LSM). The approach allows the comparison of modelling/imaging parameter configurations with greater confidence than simply viewing the migrated images. The method is best suited to determining discrete parameters but can be used for continuous parameters albeit with greater computational expense. Introduction When performing seismic imaging or modelling there are a number of potentially unknown parameters which may need to be determined. Many of these are estimated and the approximations may
