    Abstract: A method and system that characterizes hydrogen sulfide in petroleum fluid employs a tool that includes a fluid analyzer for performing fluid analysis (including optical density (OD) for measuring carbon dioxide concentration) of a live oil sample, and a storage chamber for an analytical reagent fluidly coupled to a measurement chamber. An emulsion from fluid of the sample and the reagent is produced into the measurement chamber. The reagent changes color due to pH changes arising from chemical reactions between components of the sample and the reagent in the measurement chamber. The tool includes an optical sensor system that measures OD of a water phase of the emulsion at one or more determined wavelengths. The pH of the water phase is derived from such OD measurements. The pH of the water phase and the carbon dioxide concentration in the sample is used to calculate hydrogen sulfide concentration in the sample.

  • Patent number: 7445934
    Abstract: A method and apparatus is described for estimating terminal purity or terminal contamination for a fluid during the withdrawal of the fluid from a subsurface formation. The apparatus and method provide for measuring refractive index of the fluid over a time period, fitting a curve through the refractive index measurements or data values derived therefrom and estimating a terminal refractive index or terminal value for the data values from the fitted to curve to estimate the terminal contamination or purity for the fluid.

  • Patent number: 7427504
    Abstract: A method for analyzing formation fluid in earth formation surrounding a borehole includes storing analytical reagent in a reagent container in a fluids analyzer in a formation tester and moving the formation tester, including the reagent, downhole. Reagent from the reagent container is injected into formation fluid in the flow-line to make a mixture of formation fluid and reagent. The mixture is moved through a spectral analyzer cell in the fluids analyzer to produce a time-series of optical density measurements at a plurality of wavelengths. A characteristic of formation fluid is determined by spectral analysis of the time-series of optical density measurements.

  • Patent number: 7393689
    Abstract: The present invention provides a method and apparatus or system for determining an amount of coal tar that can enter, and subsequently be displaced from, a given type of soil for a range of depths of the soil. The method and apparatus also provide verification of the pressure at which coal tar can be displaced from a given type of soil. In particular, the method and apparatus simulate the hydrostatic pressure that a soil sample encounters in the subsurface of the ground. Accordingly, the method and apparatus provide a relationship between the concentration of coal tar in the soil and the pressure required to displace the coal tar from the soil, which allows for an estimation of the amount of coal tar that may be displaced at a particular location or site. Further, the method and apparatus are adaptable for use in the laboratory or the field.

  • Patent number: 7223602
    Abstract: The invention provides a method of online and on-site tracer generation for tagging natural gas stored in underground storage fields wherein feedstock is drawn from a feedstock source. The feedstock undergoes initial analysis to determine hydrocarbon levels. The feedstock then undergoes reaction to produce tracers such as ethylene, propylene, acetylene hydrogen and carbon monoxide. The feedstock is then analyzed to determine post reaction tracer concentration. The feedstock including generated tracers is then introduced back into the feedstock stream. Tracer levels in the pre-reaction or initial analysis of feedstock are compared with tracer levels in the post-reaction feedstock and the rate of flow of feedstock through the system is adjusted to achieve a predetermined level of tracer concentration. The level of tracer concentration will then be used to identify the particular natural gas charge in a storage field.

  • Patent number: 7221448
    Abstract: The invention relates to a sample cell with a glass body comprising a gas inlet and a gas outlet and at least one orifice, a plane glass window is fused into the orifice, the shape and size of the window corresponds to the shape and size of the orifice, the orifice is limited by a rim, the rim is wider than the thickness of the window, the rim of the window is fused with the rim of the orifice. The invention further relates to a method of producing the sample cell. The window is inserted into the orifice. The rim of the orifice is heated several times from the exterior in such a way that the glass melts and a fused joint is formed between the window and the rim of the orifice. The sample cell produced by the method has a particularly rigid joint between the window and the glass body. Therefore, this glass cell is able to withstand pressures above 10 bar and allows the passage of light without lens effects owing to its plane-parallel windows. The sample cell is used in a polarizer for inert gas.

  • Patent number: 7098034
    Abstract: Methods, systems, and computer program products analyze asphalt samples for anti-stripping agents by: obtaining a sample comprising asphalt binder material; sensing a selected parameter associated with the sample (such as the acidity and/or alkalinity of the sample); and analyzing the sensed parameter to assess at least one of: (a) the presence of at least one anti-stripping agent in the sample; and (b) the level of at least one anti-stripping agent in the sample. The sample can be heated so that it emits exhaust gas and the exhaust gas (directly or indirectly) interrogated to determine its pH, or other constituents or properties, such as ammonia. Pre-defined mathematical relationships can be used to correlate the measured sensed data to the concentrations of the anti-stripping agent(s) in the sample undergoing analysis. The evaluation can be carried out in a generally automated rapid manner so that the test can be completed in about 10 minutes or less. Related devices and kits are also described.

  • Patent number: 7008793
    Abstract: The present invention is intended to take a sample of an emulsion circulating in a line. The emulsion is momentarily diverted from the main circulation line 1 thereof to a bypass line 2. By restoring circulation of the emulsion in main line 1, an emulsion sample still present in bypass line 2 is confined under pressure. The emulsion sample is then stabilized according to a well-known method. Since the size and the distribution of the drops no longer evolve with time, the sample can be observed and analyzed after sampling. The invention more particularly applies to the field of petroleum industry and it is notably intended to take a sample of a petroleum effluent in form of an emulsion at wellheads.

  • Publication number: 20040253734
    Abstract: A non-electric down-hole formation pressure monitoring system utilizing typical down-hole chemical injection system technology as the basis for pressure data acquisition combined with surface computer integration whereby a constant and accurate picture of formation pressure variations may be obtained and recorded at minimum cost. Computer integration into the chemical injection system allows the pressure differential across the pressure balanced valve located adjacent the chemical injection orifice into the well production casing to be exploited by manipulation of the injection pump pressure thereby maintaining a constant differential pressure across the check valve providing a means for tracking the well formation pressure up or down. Pressure variations in the chemical injection capillary tube on the pump side of the remote pressure balance valve mimic formation flow characteristics which may be monitored by the computer at the surface where pump noise and plumbing noise due to vibration etc.
