HOUSTON –TGS-NOPEC Geophysical Co. has completed a new depth migration of 3D data from the Mississippi Canyon GoM OCS. The "Revival Kirchhoff" data volume was processed by TGS and designed to refine the velocity model using anisotropic parameter estimation and subsalt tomographic inversion.

"The Revival Kirchhoff volume was also calibrated with 247 wells provided by our Geological Products division," says Zhiming Li, senior VP of Imaging Services at TGS. "The resulting model was then used to migrate the data using our proprietary 3D Anisotropic Kirchhoff Depth Migration algorithm to produce a 3D cube that accurately ties to well information and provides unprecedented quality beneath and around salt."
