Joint inversion of rf and surface wave canada
NettetJoint inversion—also called static seismic inversion—uses inverse modeling techniques to solve for acoustic and elastic rock properties from 2D and 3D seismic data. Our team … Nettetdifferent sensitivities (e.g. surface wave dispersion measure-ments) can be included in a consistent manner. The result is a general probabilistic joint inversion methodology, where no explicit ‘tuning’ is needed to weight different datasets. 1.1. A Brief History of RF Inversion The RF inverse problem is highly non-linear and non-
