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. 

  • Data on Cloud (Partnership with Tape Ark)
    Moving large volumes of ageing archive data on legacy tape in physical storage centers – hence inaccessible and decaying in its current form - to the cloud. Liberating this vast volume of data to the cloud so that it is accessible for data analytics, artificial intelligence (AI) and machine learning (ML) technologies. Transferring data to cloud not only ensures its preservation, but empowers the client to monetize the data – Through learnings and discoveries, which lead to new knowledge or increased operational efficiencies. Or, turning it into revenue source rather than a cost center.
