More topics on geophysics and programming.

See four kinds of geophysical tomography.
Here is my derivation of Morlet wavelet transforms with an application to Kirchhoff migration.
Avoid interpolation artifacts in Stolt migration.
Here are some techniques for Signal/noise separation and seismic inversion. Much of this material was published in three articles in the SEG's Geophysics journal. I'm fond of appendices A, B, C, and D. The extraction of coherent wavelets on pages 46-52 is an important unpublished detail.
Seismic migration is often the adjoint of linear acoustic modeling. Better, you can derive least-squares and pseudo-unitary migration.
Solve 3D reflection statics for large datasets.
Here is a derivation of anisotropic elastic raytracing from only conservation of momentum and Hooke's law.
Seismic amplitudes are "preserved" if the changes can be inverted.
Here's my attempt to motivate the logistic function, useful for predicting oil production.
Hans Tieman has a clever method of transforming common-midpoint slant stacks to common-source.
I prefer depth-focusing analysis to common-focus-point gathers.
Fuzzy logic is inferior to probability.
Programming for geophysics, a presentation at the Center for Wave Phenomena annual meeting, Colorado School of Mines, May 21, 2008.

Intellectual-property patents are evil.
Present employer exempted, I believe in the the inverted pyramid of corporate responsibility.
Managers should have a clearly defined role.
Here's some advice for editors with the journal Geophysics.
Here are outside links I use..
