Title: The Innovative Contributions of Stephen J. Chapman
Introduction
Stephen J. Chapman is a notable inventor based in San Francisco, CA. He has made significant contributions to the field of seismic survey technology. His innovative approach has led to the development of a unique method for adaptive minimum-phase deconvolution.
Latest Patents
Chapman's most recent patent is titled "Surface-consistent minimum-phase deconvolution." This method effectively removes source and receiver wavelet variations in a surface-consistent manner from traces of a seismic survey. The process involves selecting a plurality of source-pairs and receiver-pairs from the traces, performing cross-correlations, and stacking the signals to obtain an amplitude frequency spectrum for each source and receiver wavelet. The method culminates in the determination of a two-sided finite-length time domain deconvolution filter for each location, which is then used to deconvolve the trace.
