Abstract: A method of calculating the salt content of water in a multiphase flow which comprises irradiating a body of the multiphase flow with radiation of three distinct energy levels; measuring the intensity of the transmitted radiation at each of the energy levels; and using the measurements of transmitted radiation as obtained from calibration and radiation mass attenuation coefficients for hydrocarbons for each of the energy levels, to calculate a unique function representing the salt content of the water. The three energy levels can as an example be provided by the radioactive isotope Barium 133 and the radiation mass attenuation coefficients for hydrocarbons can be calculated theoretically or derived from static calibration measurements. The invention is particularly suited for the measurement of water salinity in a stream comprising a mixture of oil, water and gas, i.e. a multiphase flow, without separating the phases. It is required to accurately determine the water phase salinity and to use the measurement to calibrate the other sensors or measuring equipment. In addition the water salinity is often of interest to the well operators as an absolute value which may then be compared with other wells or monitored over a period of time.

Abstract: An optical clean-up filter is produced that has a desired spectral response. This is done by first decomposing the desired spectral response into individual simulated responses using a suitable computer program. Then tapered fiber filters are manufactured with parameters that closely match the individual responses. And finally the tapered fiber filters are concatenated on a single-mode fiber to produce the optical clean-up filter with a total response that closely matches the desired spectral response.

Abstract: A method and apparatus is described for making multichannel measurements of weak signals in noisy environments. The method is based on an adaptive compensation technique in which the large interfering background signal is first recorded by using the apparatus itself. By a statistical analysis of this multichannel measurement the independent components of the interference are determined. The apparatus is provided with compensator elements which are properly coupled to individual sensors for both to collect and distribute information on the interference during the measurement. The proper couplings are derived from the interference measurement mentioned above. In this way the output of the device can be made immune to the large amplitude interference components present in its environment. This reduces the dynamic range requirement for the data transport and storage systems.
