Latest Patents

David F Norwood holds a patent for a "Method for processing signals from an MWD electromagnetic resistivity." This invention discloses an adaptive deconvolution method aimed at enhancing the vertical resolution of MWD electromagnetic resistivity logging tools. The tool measures the total differences between the voltages induced in a pair of spaced-apart receiver coils. A deconvolution filter, tailored to the current position of the logging tool in the borehole, is derived based on the weighted average of the measured phase differences. By utilizing this deconvolution filter, the measured phase differences are spatially deconvolved, thereby enhancing the vertical resolution of the measurements and reducing shoulder-bed effects.
