Abstract:
A method for determining values of anisotropic model parameters of a Tilted Transversely Isotropic (TTI) Earth model, the method including obtaining an initial TTI earth model that substantially flattens common-imaging-point gathers and substantially ties seismic data to well data; inputting checkshot data and/or VSP data to determine updated values of Vp0 near the well locations; determining an incremental improvement Δδ; extrapolating the relative change Δδ from near-well locations to the entire three dimensional TTI earth model; determining updated values of Vp0=Vp0 (1−Δδ); inputting near-to-mid-offset/angle and mid-to-far-offset/angle residual moveout information; and providing updated values of δ and η.
