Abstract
A new inversion procedure to estimate the interval velocities model is presented in this paper. This is based on the search of two normal-incidence point (NIP) wavefront attributes, namely the radius of curvature and the incidente angle. These attributes are determined with help of one coherency analysis, that is applied to a set of seismic traces pertaining to the multicaverage reflection data corresponding to one common-reflection- point, the so-called Common -Reflecting-Element (CRE) gather.
