Fermat's Principle and Hamilton's Principle: Does a least action take a least time for happening?
We explore deeper and analyse in more detail Fermat’s and Hamilton’s principles. We try to address some questions: Is it …

On discriminating sand from shale using prestack inversion without wells: A proof of concept using well data as a surrogate for seismic amplitudes
A new method has been developed to discriminate sand from shale, from P-wave velocity, S-wave velocity, and density values obtained …
