Pdf A Fast Least Squares Reverse Time Migration Method Using Cycle We propose a fast least squares reverse time migration method based on cyclegan. in the proposed method, cyclegan is used to approximate the inverse hessian matrix to play the role of a deblurring operator that acts directly on the rtm imaging results. We simulate the inverse hessian by training a cycle consistent generative adversarial network (cyclegan) to construct a mapping relationship between the rtm results and the true reflectivity.
Pdf Least Squares Reverse Time Migration With Variable Density With high imaging accuracy, high signal to noise ratio, and good amplitude balance, least squares reverse time migration (lsrtm) is an imaging algorithm suitable for deep high precision oil and gas exploration.
