| titleOfInvention | Borehole measurements using a fast and high energy resolution gamma ray detector assembly |
| abstract | A gamma ray detector assembly for a borehole logging system that requires the measurement of gamma radiation with optimized gamma ray energy resolution and with fast emission times required to achieve meaningful measurements in high radiation fields. The detector assembly comprises a lanthanum bromide (LaBr3) scintillation crystal and a digital spectrometer that cooperate with the crystal to maximize pulse processing throughput by digital filtering and digital stacking or coalition inspection of the pulses. The detector assembly is capable of digital pulse painting and digital stacking or coalition inspection with a dead time of less than 600 nanoseconds per second. event. Pulse height can be accurately measured (corrected for stacking or coalition effects) for 2 pulses separated by as little as 150 nanoseconds. Although the invention is applicable to virtually any borehole logging methodology that uses the target of gamma radiation in harsh borehole conditions, the invention is particularly applicable to carbon / oxygen logging. |
