Simultaneous inversion for fast azimuth and dispersion of borehole flexural waves using cross-dipole data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2002)
This paper presents an inversion algorithm for obtaining azimuthal angle and borehole flexural wave dispersion in an anisotropic formation. The technique constructs an objective function that can be minimized using standard ...
A stretched grid finite-difference time-domain scheme implemented with anisotropic perfectly matched layers
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2002)
A stable 2.5D finite difference time-domain (FDTD) scheme is developed to study wave propagation in heterogeneous media. On example is the logging while drilling configuration where small features such as the annulus between ...
