Paper Number: SEG-2019-3214684
... is raised by iterating inversion via multi-scale seismic inversion. The constraint of low frequency can improve resolution furtherly by proposed method. More precisely, low frequency information of P-wave impedance is obtained by large scale inversion. On this basis, high frequency information of P...

... resolution is improved by iterating inversion. Moreover, the inversion results have the abundant high frequency information and low frequency information. At last, 1-D model and real seismic data are processed by proposed method to show the practicality and reliability of proposed method. Presentation Date...

... these traces shows that the borehole seismic (such as VSP and crosswell seismic) data can provide quite reliable high frequency information, which is very important to improve the resolution of surface seismic data. These characteristics are also found in the actual seismic data. The relation of the...

... paper, we propose to use Spline Envelope(SE) to reconstruct the low frequency information, and then use it for Spline Envelope Full Waveform Inversion(SEFWI) to restore the macro structure of velocity model, so that the initial model dependence of FWI can be reduced. We derive the objective function and...

... to become facies-dependent, ready for a second pass of inversion. In this approach we follow the ideas of Jarvis, (2006) and Mesdag et al. (2010). Finally, we investigate methods to transfer the essential low frequency information to geostatistical inversions. Method The first step is to define the...
