Seismic model parameter estimation usingleast-squares migration

摘要

We describe a method for verifying seismic modelling parameters. It is equivalent to performing severaliterations of unconstrained least-squares migration (LSM). The approach allows the comparison ofmodelling/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 albeitwith greater computational expense.
