Abstract: Disclosed is an apparatus for estimating a property of a fluid. The apparatus includes: a piezoelectric resonator configured to be disposed in the fluid; an electrode embedded in the piezoelectric resonator and included in a resonator circuit configured to output an electrical signal related to the property; a discontinuity defined by a surface of the piezoelectric resonator, the discontinuity altering an impedance of the resonator circuit if a high-dielectric fluid or a conductive fluid is disposed in the discontinuity; and an insulating material disposed in the discontinuity.

Abstract: "método e aparelho para um espectrômetro de fluorescência de fundo de poço". a presente invenção refere-se a um aparelho e método para espectrometria de fluorescência simples em um ambiente de fundo de poço utilizando uma fonte de luz uv e fluorescência de uv para determinar um parâmetro de interesse para uma amostra de fundo de poço. a fonte de luz uv ilumina o fluido, o qual por sua vez fluoresce a luz. a luz fluorescida é transmitida de volta na direção da fonte de luz uv e através do percurso na direção de um analisador de espectro ótico. a gravidade api é determinada pela correlação do comprimento de onda de fluorescência de pico e do brilho de emissão fluorescente da amostra. a pressão de precipitação de asfalteno é determinada pelo monitoramento da razão de conteúdo de azul/verde para uma amostra que sofre despressurização.

Abstract: The invention relates to refractometry and attenuated reflectance spectrometry in a wellbore environment. Specifically, it pertains to a robust apparatus and method for measuring refractive index of fluids along a continuum (rather than in steps), and for measuring attenuated reflectance spectra, and for interpreting the measurements made with this apparatus to determine a variety of formation fluid parameters. The present invention provides a method and apparatus to distinguish between gas and liquid based on the much lower index of refraction of gas. It can also be used to monitor fluid sample clean up over time. The refractive index of a wellbore fluid is determined from the fraction, R, of light reflected off the interface between a transparent window that has a known refractive index and this fluid. Preferably, the refractive index is measured at some wavelength of light for which the fluid is not highly attenuating but is optimally attenuating. The adjacent transmission spectrometer can be used to correct the refractive index measurement for attenuation at those wavelengths, which it monitors. Also, this reflection-based refractometer design can be used as an attenuated reflectance spectrometer at highly attenuating wavelengths.

Abstract: Det beskrives en anordning for estimering av en egenskap ved et fluid eller væske. Anordningen omfatter: en piezoelektrisk resonator innrettet for å bli plassert i fluidet; en elektrode innkapslet i den piezoelektriske resonatoren og innlemmet i en resonatorkrets innrettet for å mate ut et elektrisk signal relatert til egenskapen; en diskontinuitet definert av en overflate av den piezoelektriske resonatoren, der diskontinuiteten endrer en impedans i resonatorkretsen dersom et sterkt dielektrisk fluid eller et strømledende fluid befinner seg i diskontinuiteten; og et isolerende materiale anbrakt i diskontinuiteten.
