A Denoising Method for Seismic Data Based on SVD and Deep Learning

Applied Sciences, 2022
When reconstructing seismic data, the traditional singular value decomposition (SVD) denoising method has the challenge of difficult rank selection. Therefore, we propose a seismic data denoising method that combines SVD and deep learning. In this method,

Curvelet Denoising of 4D Seismic [PDF]

66th EAGE Conference & Exhibition, 2004
With burgeoning world demand and a limited rate of discovery of new reserves, there is increasing impetus upon the industry to optimize recovery from already existing fields. 4D, or time-lapse, seismic imaging is an emerging technology that holds great promise to better monitor and optimise reservoir production. The basic idea behind 4D seismic is that
