International Symposium onInternational Symposium onGeophysical Imaging with Localized Waves

• Localized waves refer to waves localized in propagation direction-space location or/and in time-frequency. Localized waves exist both in real world, or in wavefield decomposition schemes as certain elementary waves having some preferred physical-mathematical properties.

• With phase-space localized waves, local AVA (amplitude variation with angle), local inversion for rock/reservoir parameters can be performed, and the close link between imaging and inversion can be established.

International Symposium onInternational Symposium onGeophysical Imaging with Localized Waves

• In geophysics, localized waves have been developed and applied in the recent decades as beams and beamlets, curvelets, fast beams, various forms of wave packet, in addition to the traditional Gaussian beam.

• We feel that localized waves have great potential in applications to geophysical imaging and inversion
