Detection of gas reservoir using elastic full waveform inversion in Sulige field

Allowing to take into account the full information content of the data and the complex behavior of propagating waves, full waveform inversion (FWI) can obtain not only the more accurate estimates of subsurface model parameters, but also the structural morphology, and it should have more potential for application beside providing a high-precision velocity model for the migration. In this paper, we have explored the application of full waveform inversion in the gas detection in Sulige gas field where whit strong heterogeneity and quite small difference of acoustic velocity and impedance between the gas sandstone and surrounding rock.
