摘要： An embodiment of an apparatus for estimating a parameter includes a multi-wavelength electromagnetic source configured to emit electromagnetic radiation beams having multiple wavelengths at a fixed angle relative to an interferometer, the multi-wavelength source having a stabilizer configured to lock each beam to one of a plurality of discrete wavelength ranges. The apparatus also includes the interferometer, which has a fixed reference reflector and a moveable reflecting assembly coupled to a moveable mass, the mass configured to move in response to the parameter. The apparatus further includes a detector configured to detect an interference pattern generated by the interferometer for each beam, and a processor configured to combine the interference patterns and estimate the parameter based on the combined interference pattern.

摘要： An apparatus for sensing a parameter beneath a surface of the earth includes an optical fiber disposed beneath a surface of the earth and comprising at least one fiber Bragg grating sensor configured to sense the parameter and a wide-band light source disposed beneath the surface of the earth and configured to emit light in a wide band of wavelengths to illuminate the at least one fiber Bragg grating. An optical interrogator is disposed beneath the surface of the earth and configured to receive light reflected by the at least one fiber Bragg grating sensor and to transform a shift in wavelength of the reflected light into a variation of light intensity. A photo-sensor is configured to measure intensity of light received from the optical interrogator. Electronics are coupled to the photo-sensor and configured to measure a voltage representing the light intensity at the photo-sensor to sense the parameter.

摘要： Methods and apparatus for estimating a hydrocarbon fluid parameter using a hydrocarbon fluid testing module. The method may include estimating a hydrocarbon fluid parameter value where a precipitate begins to form in a hydrocarbon fluid sample. The method may also include extracting a hydrocarbon fluid sample under pre-precipitate conditions; changing at least one hydrocarbon fluid parameter, generating information indicative of precipitate formation; and communicating the estimated value of the hydrocarbon fluid parameter at the precipitate formation point. The method may also include producing hydrocarbon fluid sample from a formation using the estimated value and a bubble point. The disclosure also includes an apparatus for implementing the method.
