.... The radiation source is a conventional Cs-137 radioisotope emitting 662 keV gamma rays that can penetrate through two metallic tubulars to reach the cement. The detector is a gamma detector that is collimated to accept gamma rays from the volume illuminated with the gamma rays and centrally positioned...

... has been widely used for more than 60 years. PN logging techniques are predominantly used in cased wells. However, PNL can be applicable in openhole conditions as well. PNL instruments include a pulsed neutron generator (PNG) and multiple scintillation gamma-ray detectors with electronics...

... a pulsed neutron generator capable of emitting 2 × 10 8 neutrons/second into the ambient formation. One was a 4-detector, 1-11/16-inch diameter reservoir evaluation tool, and the other was a single detector, 3-1/4-inch geochemical spectroscopy tool. In order to obtain the best possible results, a sound...

... there are considered several cases in three different fields: Magwa, Minagish and Abdali. Abstract The five detector pulsed neutron (FDPN) tool is one of the most advanced tools in cased-hole reservoir evaluation. The evolution of multi-detector pulsed neutron tools (MDPN) created a turning point...

... to travel to the cement-formation interface and return to the detector without being completely attenuated. For single casing configurations, results indicate that cement channels produce distinguishable results from intact cement. For through-tubing logging it cannot be concluded that detected results...
