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： Methods and related apparatuses and mixtures are described for spectroscopic detection of hydrogen sulfide in a fluid, for example a formation fluid downhole. A reagent mixture is combined with the fluid. The reagent mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and a solvent that stabilizes the metal sulfide nanoparticles and assist in preventing precipitation by electrostatic stabilization. The solvent includes a property having a density above 1 kg/l. Further, dissolving the metal ions into the solvent to create the reagent mixture, and mixing the reagent mixture with the hydrogen sulfide sample in a formation. So, the metal ions of the reagent mixture react with the hydrogen sulfide sample to form the metal sulfide nanoparticles, resulting in the metal sulfide nanoparticles having properties with a density from 1 kg/l to about 8 kg/l.

摘要： A gas separation and detection tool for performing in situ analysis of borehole fluid is described. The tool operates by introducing a reagent to a test sample and causing the resulting mixture to flow through a microfluidic channel where optical testing is performed. The optical testing detects a change in a characteristic of the reagent in response to expose to one or more particular substances in the test sample. The test sample may be borehole fluid, a mixture of borehole fluid and scrubbing fluid subsequently mixed with reagent, a mixture of reagent and gas separated from borehole fluid, or a mixture of scrubbing fluid and gas separated from borehole fluid which is subsequently mixed with reagent. A membrane may be employed to separate one or more target gasses from the borehole fluid.
