Ruggedized detectors are designed and built to meet the increasingly demanding drilling and well logging applications for oil and gas exploration. These include natural and activated gamma detection for Measurement While Drilling (MWD), Logging While Drilling (LWD) and wireline logging. We also provide the full spectrum of detection solutions for less environmentally challenged surface measurements such as multi-phase flow measurements, core & cuttings analysis, NORM & TENORM measurements.
Detectors are designed to user defined configurations to meet down hole performance and environmental requirements, as well as measurement of both natural and neutron activated gamma. Detectors are designed with high performance hermetic seals that meet these challenging requirements. Detectors can be provided as packaged crystals or integrated with ruggedized photomultiplier tubes and basic electronics.
Detectors designed to meet the challenging environments of Measurement & Logging While Drilling allow operators to have realtime feedback on drilling operations. This ensures that the drill string remains in the payzone, resulting in significant savings. The MWD tools provided by Saint-Gobain meet the stringent shock and vibration levels while providing accurate results at temperatures up to 200°C. Our NxGenTM packaging provide industry leading nuclear performance. Detectors can be provided as packaged crystals or integrated ruggedized photomultiplier tubes and basic electronics. Plated Geiger-Mueller tubes are also used for high temperature natural gamma detection.
Large sodium iodide, NaI(Tl), crystals are typically used in this application to measure ratios of naturally occurring Potassium, Uranium and Thorium. By measuring the relative concentrations of these radioelements, a geologic map of the area being surveyed can be created. With the challenges of takeoff, flight and landing, the detectors require specific packaging to both survive and perform under these conditions. Saint-Gobain specializes in detectors for these applications with industry leading energy resolution.
Saint-Gobain provides the full spectrum of non-ruggudized radiation detectors capable of measuring lower energies for many surface logging applications. These include
