Generalized ray theory for seismic waves in structures with planar nonparallel interfaces

Paul G. Richards, Dean C. Witte, Göran Ekström
Published: 01 August 1991
Bulletin of the Seismological Society of America (1991) 81 (4): 1309–1331.

... the subscript A from PA, writing p = (Px, Py) for the horizontal slowness at the source. We now have two scalar independent variables, and it is instructive to use them to reproduce the known field of a point source in a homogeneous medium. Thus, consider exoT) W(X°'w)- R , w h e r e R = IXo], which describes...

... compensation task as an inverse problem and solve it using some form of sparsity regularization. For example, Guitton and Claerbout (2017) use the hyperbolic penalty function to recover a spiky Q -compensated reflectivity series; Cooper and Poole (2017) use the sparse tau-px-py inversion to perform...

... and is given by the corresponding periodicities px and py so that BSC equals px × py /2. The usual process of data-regularization takes place at the dip moveout-stack stage, and results in averaged (over offset) amplitudes. If these averages are different (due to a different 3-D geometry for the second...
