Title: Andrejs Jurkevics: Innovator in Geophysical Data Processing
Introduction
Andrejs Jurkevics is a notable inventor based in Arlington, VA (US), recognized for his contributions to the field of geophysical data processing. He holds 2 patents that focus on methods to enhance the interpretation and processing of seismic data, which are crucial for understanding subsurface geological formations.
Latest Patents
Jurkevics' latest patents include a "Method of processing geophysical data to compensate for earth filter" and a "Method of interpreting seismic data." The first patent outlines a technique for processing seismic data to yield useful information regarding the subsurface area explored. It describes how generated seismic energy travels into a subsurface formation, where it is distorted and attenuated. The distorted seismic pulse is detected by a geophone or other seismic receiver and recorded. The received seismic traces are compensated for the attenuation effects of the earth filter, allowing for a close approximation of a zero-phase, band-limited output wavelet of the reflectivity of the geophysical formation under exploration. The second patent details a method to process seismic data, where the acquired seismic data is autocorrelated, and the amplitude spectrums are estimated, stacked, and averaged to reduce the effects of nonwhite reflectivity. This method involves cepstral windowing to eliminate rapidly varying components of the amplitude spectrum, ultimately shaping the estimated seismic wavelet into a zero-phase, low sidelobe output wavelet.
