Abstract
A method for producing a high-fidelity, high-resolution seismic image of a subsurface of a wellsite. The method includes receiving seismic data from wellsite equipment that is disposed at a wellsite. An initial estimation of an earth model is recovered from the received data and a depth migration workflow is performed that is based on the initial estimation of the earth model. The depth migration workflow may be a least-squares FWI-derived reflectively (LS-FDR) workflow. The method also includes revising the initial estimation of the earth model based on the results of the depth migration workflow in order to produce an optimal estimation of the earth model. A seismic image may then be generated from the optimal estimation of the earth model and displayed on a screen for a user. The user may then perform a wellsite action that is based on the generated seismic image.
