摘要： The present invention is a system for analyzing the energy levels of radiation detected by a radiation detector having a multichannel pulse height analyzer. The radiation detector generates signals representative of the energy level of the detected radiation, and the analyzer increments a particular channel dependent on the signal from the detector. The channel incremented by the analyzer is in response to an empirical relationship of the particular channel with respect to energy level. The empirical relationship is determined so that energy spectral peaks occurring over substantially the entire energy detection range of the detector have peak widths spanning substantially equal numbers of analyzer channels. In one embodiment of the invention, the detector is a scintillation counter responsive to gamma ray radiation. In one embodiment of the invention, the empirical relationship is approximated by an ordered expression comprising a third order polynomial function.

摘要： Measurements made by a natural gamma ray tool are used to provide an elemental composition of an earth formation. Additional measurements made with a pulsed neutron tool with two or more gamma ray detectors are used to provide a mineralogical and/or elemental image of the formation. This may be used in reservoir navigation and in furthering the understanding of the geology of the prospect.
