Chemistry, a step ahead in Rock Physics applied to Time-lapse Seismic

open access: yesProceedings of the 16th International Congress of the Brazilian Geophysical Society&Expogef, 2019
In carbonate rocks, oil production monitoring by seismic is always defiant, and things become much more difficult when this kind of reservoir is found at big depths, as in brazilian pre-salt offshore fields.

Assessing Phonon Coherence Using Spectroscopy

open access: yes, 2022
As a fundamental physical quantity of thermal phonons, temporal coherence participates in a broad range of thermal and phononic processes, while a clear methodology for the measurement of phonon coherence is still lacking.
