We formulate the derivatives of the phase and group velocities for each of the anisotropic parameters in a tilted transversely isotropic medium (TTI-medium). This is a common geological model in seismic exploration and has five elastic moduli or related Thomsen parameters and two orientation angles defining the ...
We present a new numerical scheme for 2.5-D/3-D direct current resistivity modelling in heterogeneous, anisotropic media. This method, named the ‘Gaussian quadrature grid’ (GQG) method, cooperatively combines the solution of the Variational Principle of the partial differential equation, Gaussian quadrature ...
We present an extension of the spectral element method (SEM), called the Gaussian quadrature grid technique, for 2.5-D frequency-domain seismic wave modeling in heterogeneous, anisotropic media having arbitrary free-surface topography. The technique has two new features. First, it employs a point-gridded model ...
