Dictionary:Backus averaging
An effective-medium theory[1] used to upscale sonic-log data for synthetic seismogram manufacture. Involves harmonic averaging to find the anisotropic elastic parameters that characterize seismic-wave propagation at low frequencies in a layered medium.
Named for George Backus, brother of Milo Backus.
