Unlike other devices that are commonly used to calibrate gamma tools, the KUTh verifier contains the same relative amounts of Potassium (K), Uranium (U) and Thorium (Th) as is found in the API test pits. Counts are collected and used to calculate the API correction in units of CPS per API.

QSA Global, Inc. is the leading manufacturer of high performance Am-241, AmBe, Cf-252, Cs-137, Co-60, and KUth for the Oil Well Logging, Industrial Gauging & Analysis, and Nuclear Industries, and the world-leading supplier of SENTINEL™ Iridium-192 (Ir-192), Selenium (Se-75), and Cobalt-60 (Co-60) sealed radioisotope sources to the industrial ...

2004年9月26日 · This paper will show field examples of KUTh data. The paper will also discuss procedures necessary to obtain quality measurements, will point out various savings that can be realized by an operating oil company using the new design and the information it gathers, and will present the interpretation procedures necessary to obtain a final product.

2024年7月3日 · When the kuth seedling develops three to four leaves, transfer them to the field. In the upper northern areas, kuth should be moved to flat land instead of ridges, as research shows that kath cultivated in flat land gives a higher yield than that cultivated on ridges.

2023年11月7日 · NGT-HTR是CBG最新推出的超高温伽马传感器，其专门为极端恶劣的高温钻井服务设计，典型应用如页岩油气开采。 NGT-HTR提供在 190℃的温度下完全运行并且提供稳定可靠伽马计数输出，同时其振动指标比市场上现有的伽马提升了25%，完全契合日益增长的页岩油气勘探开采应用。 基于超高温组件设计生产并调谐补偿的独特设计可降低伽马计数在高温下漂移，确保井下勘探工程中稳定的计数率输出，引导测井仪器精准钻进。 作为行业的领导者，CBG …

API Calibration performed with AEA Technology, QSA Inc., KUTh Field Verifier #188074, S/N 255 Radionuclides: K-40 (11.7%), U-238 (90 ppm), Th-232 (40 ppm). The DGA-C, Directional Gamma Tool, is a Tungsten-collimated version of the NGT-T gamma tool. These tools are sometimes referred to as “focused” or “shielded” gamma tools.

NGT-CN是在标准伽马传感器NGT-T基础上，在不改变传感器尺寸的前提下，增加了晶体尺寸，从而提升计数率40%以上，特别适合于对测量灵敏度要求更高的场合。 P/N 201-000-000. Heat/Cool Rate, Max. 17-48 VDC, 50VDC Max. * Counts are collected with gamma tool mounted within standard BeCu pressure barrel, (OD 1.875″, ID 1.500″).

KUTh measurements made with a pulsed neutron spectrometry (PNS) tool can readily precede the standard PNS formation evaluation run in a well while using essentially the same instrumentation. The PNS tool can thus replace traditional openhole KUTh measurements.

The NGT-T2 is the next generation of downhole directional drilling gamma sensor technology. It’s a complete electrical and mechanical redesign of our industry standard NGT-T Gamma Tool. After the 30-year success of our legacy NGT-T, the NGT-T2 is designed to become the new workhorse of the industry to carry it forward for decades to come.

2004年9月1日 · Field test logs, conducted with multiple sets of equipment and analyzed for both accuracy and precision, demonstrate that the new C/O system provides a solid basis for reservoir optimization...
