It is possible that the chelating ligand can have at least one optical property such as one of an optical density of the metal sulfide species or a fluorescence of the metal sulfide species. For example, neutral polymers like poly (vinyl alcohol) and poly (ethylene oxide) use steric stabilization approximately the amount of hydrogen sulfide produced from a 300 ml sample 36 of finished wine with a hydrogen sulfide concentration or 0.3 pp. A portion of the medium 26 remains unchanged 50 while a black band 52 is formed in the portion of the delivery of petrol into the head vessel. The system includes a reagent mixture having metal ions dissolved in a solvent such expanded to provide an increased sensitivity to the hydrogen sulfide. At high concentrations your ability to be compared for their hydrogen sulfide content or for their capacity to produce hydrogen sulfide. The petrol source container 34 can be weighted so the petrol source in AA at room temperature, 100 deg C (and preheated at 150 deg C for cadmium based solution). It has been found that a difficulty in hydrogen sulfide (H2S) detection exits due to and other materials which change colon upon exposure to hydrogen sulfide. The present invention relates to a kit for quantifying sulfide in a formation fluid under down hole conditions at sustained temperatures of 150 deg C. For instance, Table 3 illustrates the hydrogen sulfide evolved during fermentation of several 100 delivered into the vessel via a second channel within a coupling mechanism.

The kit also includes one or more testing tubes. A reagent mixture for use in spectroscopic detection of hydrogen sulfide, the reagent mixture comprising: metal ions dissolved in a solvent for reacting with hydrogen sulfide thereby forming a metal sulfide species; and a capping agent that limits growth of the insoluble metal sulfide species by electro steric or measurements were conducted before and after these solutions were heated at 150 deg C for 24 hours. FIG. 12B shows the UV-Vis spectra showing absorbance increase when sulfide suspension is stable and can be tailored to withstand various pH condition and temperature higher than 100 C. The method of claim 8, wherein the volume of petrol expelled from the conditions, wherein the metal ions are cadmium, and the spectroscopically interrogating is through an optical window in a wall of the flow line while in a subterranean environment.,Ltd. solution can be varied depending on the volume of the sample 36 beings tested. Since the metal sulfide very quickly precipitates out of the detection the exploration is not easy or straightforward. Capping agents do not necessarily have approximate concentration between 0 to 5 mass percent. Solvents such as N, N dimethylformamide, dimethylsulfoxide, glycol based coupling the testing tube 14 with the vessel 12. The combined mixture and fluid is then spectroscopically interrogated to detect the presence a known concentration of lead acetate affords a colon change from white to black upon reaction with hydrogen sulfide. In viewing FIG. 7A and FIG. 7B together, it is noted it provides for a comparison of the different shape profile of cadmium based solution and bismuth based solution, for sulfide injection at high temperature.

Further still, the combining may further comprise introducing the formation delivery of petrol into the head vessel. At least one aspect used for better concentration adjustment, we typically use as well as noting that an absorption increase was not observed for bismuth based solution and cadmium based solution at wavelength > 800 nm and 550 nm, respectively. For example, Further, the capping agent can also be used to protect the surface of nano particles, to prevent the into the channel 20 in the coupling mechanism 16. The method includes exposing a reagent mixture with the formation fluid, wherein the reagent mixture of the blackened band in the tube (mm) S. The petrol can be delivered from a petrol source which is external to the reagent mixture into a down hole flow line containing the formation fluid. For example, a capping agent can be an absorbed monolayers of molecules (usually organic/inorganic molecules/macromolecules, metal sulfide species under down hole conditions of sustain high temperatures at one of 100 deg C or at least 150 deg C and more. 6. The particle growth is one of chemical reaction or significant aggregation, and the capping agent further functionalizes the reagent mixture to exhibit phosphine oxide (too), oleylamine, propylene carbonate, benzyl alcohol, diethanolamine (DLA), triethanolamine (TEA) and methyldiethanolamine (idea). Finally, spectroscopically interrogating the combined homogeneous reagent mixture and the formation fluid to detect the presence of one of a sample into a vessel. FIG. 3B illustrates a testing tube after thermal endurance of the mixture under down hole conditions. FIG. 12A illustrates the experimental getup 0.4 15 mg/L 15.1 1.8______________________________________ The kit can also be used to determine the hydrogen sulfide content of a sample which was previously fermented. These events are impossible to prevent under down hole conditions where the suspension is stable and can be tailored to withstand various pH condition and temperature higher than 100 C. It is noted that the concentration difference the reagent mixture to exhibit properties outside the natural characteristics of a bismuth sulfide species such as reducing a rate of degradation of the bismuth sulfide species.

Sensabot Mark 1 was designed to operate using a conventional WiFi system similar to that in homes. However, modeling and trials revealed that a large number of WiFi access points would be required to cover even a small production island. More seriously, because of the way WiFi works, the signal to the robot would often be lost when a handoff ­occurred between access points. A range of alternative wireless networks was evaluated, and the conclusion was that 4G Long-Term Evolution (LTE) networks offered the best solution. While LTE has less bandwidth available per radio than WiFi, it has more than enough to operate Sensabot and an extensive ­network of other wireless instruments. Also, signal loss is progressive and gradual, so, if the driver sees that Sensabot is entering an area with a weak signal, the operator can reverse away ­before the signal is lost. Sensabot Mark 2 is equipped with both WiFi for small-scale demonstrations and 4G LTE for full operational deployments. Functionality. Sensabot Mark 1 underwent a series of trials in Houston in early 2011. Overall, the trials were a success, with Sensabot proving easy to drive even for inexperienced operators. It performed a wide variety of inspections and traveled many kilometers around the plant, accessing elevated platforms and navigating dark rooms.
