Abstract
We present 3D anisotropic imaging results using transverse isotropy parameters together with tilt angle and azimuth. The resulting parameterization can be used to provide full spatial variation in the orientation of the transverse isotropy axis, or by restricting values of the two rotation angles, can be made to reduce to conventional VTI, HTI, or TTI cases. Using the new combination of parameters in an imaging procedure based on the adjoint method, we demonstrate advantages of the new approach for resolving complex anisotropic structures. With a strategy to mitigate nonlinearity, we show that spatially variable tilt angle and azimuth can be quickly recovered from a starting model without such variations. These capabilities are demonstrated through tests with a 3D model of a salt dome.
