Frequency Dependent DHI

This innovative service is offered by Samit in collaboration with experts from Apex Spectral, USA using their patented ADF ® Technology. This fully commercialized technology enables imaging the effects of frequency dependent P-wave velocities (dispersion) in standard seismic data (ADF®).


Contrary to Amplitude based DHI, Frequency Based DHI rely on the phenomena of frequency dependent velocity due to dispersion in a fluid saturated medium. The deformation in reflected wave shape due to fluid presence is measured by ADF (Alpha Dominant Frequency). The methodology works as a permeability measurement tool and also as a DHI tool.
