Title: Steve Michael Kelly: Innovator in Seismic Data Imaging
Introduction
Steve Michael Kelly is a notable inventor based in Houston, TX, with a focus on advancements in seismic data imaging. He holds a total of four patents that contribute significantly to the field of geophysics and seismic analysis. His innovative methods enhance the accuracy and efficiency of interpreting seismic data, which is crucial for various applications in the oil and gas industry.
Latest Patents
One of his latest patents is a method for imaging pre-stack seismic data. This method involves calculating an individual reflectivity for each frequency in the seismic data, followed by determining a mean reflectivity over these individual reflectivities. A variance is then calculated for the set of reflectivities versus frequency, and a second variance is computed for the upgoing wavefield using the mean reflectivity. A spatially varying pre-whitening factor is calculated based on these variances, allowing for a more accurate reflectivity calculation at each location.
Another significant patent by Kelly is a method for downward extrapolation of pre-stack seismic data. This process begins with determining a migration interval in the seismic data set and selecting a maximum error criterion for this interval. The maximum relative error in phase is calculated as a function of frequency, propagation angle, and the relative variation in velocity. The type of extrapolation to be used is then determined based on the comparison of the maximum relative error in phase to the maximum error criterion, with options including Gazdag phase-shift extrapolation, split-shift Fourier extrapolation, and implicit finite difference extrapolation.
