Latest Patents

Yongchang Ji holds a patent for "Systems and methods for noise attenuation of land continuous records." This invention discloses systems and methods for the attenuation of coherent environmental and source-generated noise in a continuously recorded domain of seismic survey testing. Rather than applying universal de-noising techniques to conventional gathers after source de-blending, the system and methods discussed focus on estimating and removing noise directly on continuous records by leveraging the noise characteristics in the domain of natural recording. Such techniques may be applied to coherent environmental and source-generated noises on seismic data as well as other data and noise types. Driven by the noise types encountered in the field, the methods of noise attenuation may be based upon time-frequency domain rank reduction techniques. Furthermore, to model signal and/or noise, low-rank approximations are employed in conjunction with other techniques such as operator design and unsupervised learning. Yongchang Ji has 1 patent to his name.
