A workflow of azimuthal inversion is presented and successfully applied on a wide-azimuth seismic dataset. This workflow is based on a novel approach to quantitatively extract anisotropy information in a horizontal transverse isotropic (HTI) medium. The method was first described by Mesdag (P. Mesdag, personal communication, 2016) and mimics anisotropic reflectivity behavior by isotropic forward modeling and anisotropy-transformed elastic properties (Mesdag, Debeye and Bornard, 2015). In this paper, a concept of an zimuthally varying ow requency odel (ALFM) is also introduced and demonstrated. The ALFM provides anisotropy information below seismic bandwidth, hereby reducing side-lobes of inverted magnitude of anisotropy, thus allowing better anisotropy characterization.
