摘要： Et apparat for å estimere en egenskap til et fluid i et borehull som gjennomskjærer jordgrunnen innbefatter piezoelektrisk materiale som er anordnet for i det minste delvis å neddykkes i fluidet og har innstøpt et første elektrodepar og et andre elektrodepar. En elektronikkenhet er koblet til det første elektrodeparet og det andre elektrodeparet og anordnet for å måle bevegelsesimpedans for fluidet forårsaket av bevegelse av det piezoelektriske materialet ved å påføre en første elektrisk stimulans på det første elektrodeparet og en andre elektrisk stimulans på det andre elektrodeparet og ved å motta et første elektrisk signal fra det første elektrodeparet og et andre elektrisk signal fra det andre elektrodeparet for å estimere egenskapen. Den resulterende bevegelsesimpedansmålingen har redusert påvirkning fra elektriske egenskaper ved fluidet.

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 (204) and an optically clear UV coupler (202) and a fluid containment system (301, 302). 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 (305), 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 (308).

摘要： 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.

摘要： 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.

摘要： The present invention provides a simple, robust, and versatile high-resolution spectrometer that is suitable for downhole use. The present invention provides a method and apparatus incorporating a spinning, oscillating or stepping optical interference filter to change the angle at which light passes through the filters after passing through a sample under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates are placed between the filters to isolate each filter's photodiode. The spectrometer of the present invention is suitable for use with a wire line formation tester, such as the Baker Atlas Reservation Characterization Instrument to provide supplemental analysis and monitoring of sample clean up. The present invention is also suitable for deployment in a monitoring while drilling environment. The present invention provides a high resolution spectometer which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio (GOR). Gases such as CO 2 are also detectable. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated with the present invention by using a suitable training set and chemometrics, a neural network, or other type of correlation method.
