A new approach to slant stack processing: An X-window (OSF/motif) project
A new definition for slant stack and inversion has been formulated. The different p ranges with different frequencies in the forward slant stack provide accurate reconstruction of the original data. The computing time is ...
DMO on irregularly spaced seismic data (dip moveout)
Irregularly spaced seismic data have uneven distribution of trace midpoint density on the half-offset (h) versus common-midpoint (y) space. The deviation from uniformity disrupts the cancellation and reinforcement processes ...
A study of viscous effects in seismic modeling, imaging, and inversion: Methodology, computational aspects, and sensitivity
Real Earth media are anelastic, which affects both the kinematics and dynamics of propagating waves: Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous ...
Traveltime solution for the two dimensional Eikonal equation in an arbitrarily complex slowness field via first or second order conservative upwind difference formulations
The determination of first-arrival seismic traveltimes radiating outward from a point-source in an arbitrary slowness field plays an important role in methods which require knowledge of curved wavefronts in a complex domain. ...
