摘要： A fluid separation method for performing fluid analysis of an unfiltered fluid. The fluid separation method includes providing a structure with a fluid analyzer and a power supply. Using a substrate for receiving a fluid flow stream of a multiphase mixture through a fluid sample inlet, wherein the substrate interconnects with the structure. Providing a membrane disposed across the fluid sample inlet for separating a fluid of interest from the multiphase mixture, wherein the fluid flow stream of the multiphase mixture has a shear rate that prevents a fouling of the membrane. Finally, the fluid separation method includes the substrate having fabricated channels, such that the fabricated channels are arranged substantially tangent to the fluid stream downstream of the porous membrane.

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.
