Wave equation based seismic inversion is a new technology employing robust wave equation modeling and hybrid optimization techniques for the inversion of prestack migrated data. Standard seismic inversion techniques employ convolutional models and use full stack or angle stack methods. InverSeis™ employs wave equation modeling and works directly on prestack migrated data which have the NMO removed, thus honoring the physics of the problem. In addition, InverSeis™ can work with only primaries or with primaries and multiples. The computed elastic parameters from prestack migrated gather inversion are P-wave velocity, S-wave velocity and density. For each computed elastic parameter a pdf or simply minimum and maximum values are also computed. The use of the inverted elastic parameters provides a robust and new way for lithology/fluid discrimination, porosity estimation and net to gross estimation.
