Abstract: A system and method of sensing fluid in a wellbore, where fluid along a range of radial locations in the wellbore is diverted along a flow path that runs adjacent a fluid sensor. Diverting the fluid from the range of radial locations provides a representative sample of the fluid flowing in the wellbore. Further, the diverted fluid forms a continuous volumetric flow past the fluid sensor to avoid fluid stagnation adjacent the fluid sensor. Diverting the fluid flow can be accomplished by elongate diverter wings attached at discrete circumferential locations around an outer surface of a fluid sensor and that project at oblique angles to the direction of flow. Elongate members can be used for diverting flow, where the distal ends of the elongate members attach to a downhole tool, and vane members span across selected adjacent members for directing flow to the sensor.

Abstract translation: 一种用于感测井眼中的流体的系统和方法，其中沿着井眼中的径向位置范围的流体沿着邻近流体传感器运行的流动路径转向。 从径向位置的范围转移流体提供了在井筒中流动的流体的代表性样品。 此外，转向流体形成经过流体传感器的连续体积流，以避免邻近流体传感器的流体停滞。 流体流动可以通过连接在流体传感器的外表面周围的离散圆周位置并且以与流动方向倾斜的角度突出的细长转向翼来实现。 细长构件可以用于转向流动，其中细长构件的远端附接到井下工具，并且叶片构件跨越所选择的相邻构件，以将流引导到传感器。

Abstract: Estimating parameters of interest of a formation, including density, porosity, and fluid saturation. Methods relate to gamma ray energy spectra calibration for a radiation detector including generating a calibration radiation spectrum using measurements of radiation with the detector in a time interval wherein the radiation comprises predominantly gamma rays emitted by decay of radionuclides produced by neutron activation reactions resulting from neutron irradiation, the time interval following a prior time interval corresponding to thermal neutrons produced from the irradiation; making at least one other radiation measurement with the detector outside the time interval; and producing a calibrated radiation measurement from the at least one other radiation measurement using the calibration radiation spectrum. The measurements may be taken in the time interval by conveying the radiation detector in the borehole at high speed and using a background gate of the detector.

Abstract: Borehole logging methods for estimating a parameter of interest using nuclear radiation. Methods include estimating a water saturation of the formation from gamma radiation from at least the formation detected in the borehole using a radiation detector, the gamma radiation responsive to a pulsed neutron source and resulting from at least one of: (i) decay of nitrogen-16 formed by activation of oxygen-16, and ii) inelastic scattering of neutrons from oxygen. This may include using at least one processor to: obtain a gamma ray count measurement, representing gamma rays from one of (i) the decay of nitrogen-16 (ii) and the inelastic scattering, and estimate the water saturation using the gamma ray count measurement and a model comprising a relationship between measured gamma ray counts and modeled gamma ray counts from each of a fully water saturated formation and a minimally water saturated formation.
