Latest Patents

Donald A. Phelps holds a patent for a "Spectral gamma ray logging-while-drilling system." This invention provides a method for determining concentrations of naturally occurring radioactive elements in earth formations by analyzing gamma ray energy spectra. The system utilizes at least one gamma ray detector while the borehole is being drilled. The gain of the gamma ray detector is automatically controlled through the analysis of the spectra. The detectors are strategically placed at the periphery of the downhole instrumentation to maximize sensitivity. This technology measures elemental concentrations of potassium, uranium, and thorium as a function of depth in the borehole or in azimuthal sectors around the borehole wall.
