Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3584012
... Though many successful deghosting applications have been reported, deghosting of acquisitions in shallow water with deep-towed streamers is still challenging. High curvature events cannot be focused properly using a linear Radon transform and as a consequence the sparsity constraint performs...

... automatically in isolating diffracted multiples in Radon domain. This method first computes an apex-shifted Radon transform using a L0 optimization that gives the sparsest Radon coefficients. Those sparse coefficients provide a guide for the time-space localization of multiples. Using the focused energy from...

Paper Number: SEG-2021-3583043
... We introduce a method to estimate dispersion images for surface waves and guided waves using a hybrid linear-hyperbolic Radon transform and sparse inversion. The hybrid Radon transform can model both reflections and surface waves in the data more accurately than the standard linear Radon...

... We have developed a new iterative method for simultaneous source separation (deblending). The proposed technique adopts the robust sparse Radon transform to define a coherence pass operator, which, used in conjunction with the steepest descent method, guarantees solutions that honor simultaneous...

... We propose a deep neural network (DNN) framework for computing hyperbolic Radon transform for separating primary reflections and multiples. The basic idea is to compute the weights associated with the inverse Hessian using the DNN for training data sets, which can then be applied to the adjoint...

... The Radon transform (RT) is recognized as an important tool in seismic processing for its focusing properties of seismic events in the Radon domain. The basis function of least-squares 3D tau- p transform does not fully match the 3D linear noise (i.e. field ground roll). However, that leads...

Through extensive analysis and application of existing technologies to actual data, we present an effective workflow to suppress those interlayer multiples for land data. We first deployed Radon transform in domain to eliminate multiples with large cycle. Then we suppressd...
