Title: Yiu-Wa A Lau: Innovator in Seismic Data Processing

Introduction

Yiu-Wa A Lau is a notable inventor based in Houston, TX, who has made significant contributions to the field of seismic data processing. With a total of 4 patents to his name, Lau's work focuses on improving the accuracy and efficiency of seismic data interpretation.

Latest Patents

One of Lau's latest patents is a method for identifying and removing multiples from seismic reflection. This velocity-independent method predicts surface-related multiples in any gather of seismic data traces. The process involves regularizing the gather of seismic data traces, performing a double Fourier transformation, decomposing the transformed data into amplitude and phase spectra, and estimating the surface-related multiples. This method can be utilized for automated velocity determination or for multiple attenuation in the original data.

Another significant patent by Lau is a method for removing non-geologic amplitude variations from seismic data. This method is based on the understanding that lateral amplitude variations with spatial wavelengths shorter than the width of the Fresnel zone cannot be caused by changes in the reflectivity of the target. Instead, these variations are attributed to non-geologic causes. The method allows for the identification and removal of these non-geologic amplitude effects, which can be implemented manually or automatically by a computer.
