摘要： A formation fluid sample is exposed to a rigidly-supported semi-permeable membrane such as silicone rubber to permit diffusion of gases and vapors from the formation fluid into a vacuum chamber, while at the same time, blocking the passage of any liquids. The membrane-transmitted gas is analyzed in the vacuum chamber by a sorbent-coated resonator. The sorbent absorbs gas and changes the resonant frequency of the resonator to indicate the presence of a gas. An ion pump or sorbent is associated with the evacuated chamber to maintain the vacuum. The ion pump or sorbent removes gases and vapors from the chamber that diffuse into the chamber from the reservoir sample that is on the opposite side of the semi-permeable membrane.

摘要： The invention comprises an apparatus and method for simple fluorescence spectrometry in a down hole environment. The apparatus and method utilization of two UV light bulbs and an optically clear UV coupler and a fluid containment system. The optically clear UV coupler and fluid containment system are made of sapphire. The apparatus is attached in a manner that enables light transmitted from a light source on the far side of the fluid containment system to pass through a pathway in a plate holding the UV bulbs. UV light illuminates the fluid, which in turn fluoresces light. The fluoresced light is transmitted back towards the UV bulb mount and through the pathway towards an optical spectrum analyzer.

摘要： A cooling system in which an electronic device or other component is cooled by using one or more solid sources of liquid vapor (such as polymeric absorbents, hydrates or desiccants that desorb water at comparatively low temperature) in conjunction with one or more high-temperature vapor sorbents or desiccants that effectively transfer heat from the component to the fluid in the wellbore. Depending on the wellbore temperature, desiccants are provided that release water at various high regeneration temperatures such as molecular sieve (220-250° C.), potassium carbonate (300° C.), magnesium oxide (800° C.) and calcium oxide (1000° C.). A solid water source is provided using a water-absorbent polymer, such as sodium polyacrylate. Heat transfer is controlled in part by a check valve selected to release water vapor at a selected vapor pressure.
