Title: The Innovative Contributions of Ying Ji

Introduction

Ying Ji is a prominent inventor based in Cambridge, GB. He has made significant contributions to the field of seismic data processing, holding a total of 5 patents. His work focuses on developing methods and systems that enhance the accuracy and efficiency of seismic data interpretation.

Latest Patents

Ying Ji's latest patents include a method and system for separating blended seismic data. This innovative approach utilizes a deblending method where fullband data is deblended on a source-by-source basis. The data is first decomposed into multiple subbands, and a non-equispaced subband Radon transform is employed to transform the decomposed data into the Radon domain. The deblending process is solved subband by subband by minimizing a nonlinear objective function, with the solution found using a multi-step procedure.

Another notable patent focuses on coherent noise attenuation. This invention involves methods and apparatuses for processing seismic data to generate images or determine properties of an interior section of the Earth. The seismic data is processed to filter coherent noise, such as ground roll noise, from seismic survey data. The noise is attenuated using 3D and/or 2D fan filters, which may incorporate combined low-pass and band-pass filters derived from signal decomposition. The filters are designed with selected operator length, velocity bands of signals and noises, and frequency range for a primary trace and adjacent traces within the operator length.
