摘要： Methods and related apparatuses and mixtures are described for detecting hydrogen sulfide in a formation fluid downhole. A detection mixture is combined with the formation fluid downhole. The detection mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and charged nanoparticles sized so as to inhibit significant aggregation of the metal sulfide so as to enable spectroscopic detection of the metal sulfide downhole. The combined mixture and formation fluid is then spectroscopically interrogated so as to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the formation fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.

摘要： Single point optical probes for measuring three-phase characteristics of fluid flow in a hydrocarbon well and methods of processing signals generated by the probe are disclosed. A probe having a single fiber optic is coupled to a light source and apparatus for detecting reflectance and fluorescence. Light is delivered to the tip of the probe where it either is internally reflected in the probe or exits the probe and illuminates the fluid (liquid) ambient the probe tip. If the fluid at the probe tip is oil, the light exits the probe, illuminates the oil, and causes the oil to fluoresce. If the fluid is water, no fluorescence occurs. If the fluid is gas, at least some light is internally reflected in the probe. A detection system including at least one beam splitter and fluorescence and reflectance detectors is provided in conjunction with the probe. Preferably, the fluorescence detector is coupled to the fiber optic by a wavelength division multiplexer. A preferred signal processing system for detecting oil, gas, and water provides two quasi-binary indicators: gas/liquid and oil/not oil. Three of the four possible indications (gas-not oil, liquid-not oil, and liquid-oil) give reliable results indicating whether the fluid at the probe tip is gas, water, or oil. One of the four possible indications (gas-oil) can be considered an error indicator.

摘要： Single point optical probes for measuring three-phase characteristics of fluid flow in a hydrocarbon well and methods of processing signals generated by the probe are disclosed. A single fiber optic probe is coupled to a light source and apparatus for detecting reflectance and fluorescence. Light is delivered to the tip of the probe where it exits the probe and illuminates the liquid ambient the probe tip or is internally reflected in the probe when gas is located at the probe tip. If the fluid at the probe tip is oil, the light exits the probe, illuminates the oil, and causes the oil to fluoresce. According to one signal processing method of the invention, the reflectance signal is binarized at a threshold to provide a gas/liquid quasi-binary signal which changes over time. A time fraction of the signal values is used to calculate the gas holdup. According to other signal processing methods of the invention, the fluorescence indication signal is processed by taking its derivative (and if desired a second derivative) to determine the "corners" of the fluorescence signal over time. The derivative signal exhibits a positive and a negative peak which are separated by time. The time between the peaks is used to calculate oil holdup and the amplitude of one of the peaks is used to calculate the velocity of the oil drop.

摘要： A system and method are provided for detecting fluid invasion of an annular space in a pipe structure. The system includes a thermal element and a temperature sensing element placed in the vicinity of each other in the annular space of the pipe structure. A thermal signal is generated by the thermal element. The temperature sensing element is connected to a monitor that monitors and processes the thermal signal. As the thermal signal changes when conducted through different types of fluids, the invasion of an annular space by seawater that normally contains oil or gas may be reliably detected.
