Summary: A method to construct velocity models for imaging the interior of the
Earth
Description: A method to construct velocity models for imaging the interior of the
Earth has been developed. The method uses wavefield-based methodology and
the discrepancies between images constructed using redundant seismic
experiments. This approach resembles Ful Waveform Inversion in the sense that
the complete seismic wavefields are used for velocity updates, and also
Differential Semblance Optimization in the sense that the semblance principle is
used to assess the quality of the velocity model. By blending the two techniques,
this method is more robust and efficient.
Main Advantages of this Invention:
 Does not require imaging of all data acquired in a field seismic experiment
 Improved accuracy over current methods
Potential Areas of Application:
 Oil and Gas
 Seismic Imaging
ID number: 11009
Intel ectual Property Status: WO 2013/009,944 patent pending
Opportunity: We are seeking an exclusive or non-exclusive licensee for marketing,
manufacturing, and sale of this technology.
