oa Multi-azimuth Q Inverted Full Waveform Inversion: a Data-Driven Approach for Quantifying Structural Uncertainties Beneath Gas Cloud

This abstract showcased a data driven approach i.e. Q inverted full waveform inversion that utilized dual azimuth seismic datasets. This is a method to address both the imaging and depth uncertainties on subsurface structure beneath the gas cloud. There are three elements were used for quantifying imaging and depth uncertainties such as comparison of residual move-out map, phase consistency sense check from seismic-to-well tie and total depth uncertainty maps by combining both horizon picking and velocity uncertainties maps based on the depth residual at different well locations.
