摘要： Variable volume systems and methods of use thereof described herein are capable of making calibrated determinations of fluid properties and phase behavior of a fluid sample. The determinations can be calibrated based on one or more calibration functions, such as system volume corrected for pressure and temperature variations. Cross-checking the results of measurements can be used to determine accuracy of the calibration or monitor for leaks or other anomalies of the variable volume systems. The variable volume systems can be implemented in a well logging tool and are capable of being calibrated downhole.

摘要： A method (and corresponding apparatus) for downhole fluid analysis of petroleum formation fluids. The method includes capturing in a chamber (30) of a downhole tool (10) at least two immiscible formation fluids in a generally segregated state (the fluids including petroleum), activating a fluid mixing means (62) to mix the fluids in the chamber to create an emulsion therefrom, and allowing the emulsified fluids to segregate while measuring light transmittance through the segregating fluids in order to calculate a transition time period based on the light transmittance through the fluids in the chamber. The transition time period is preferably bounded by the time required for the light transmittance values measured by the light detector to reach a baseline light transmittance. The transition time period characterizes the stability of an emulsion formed by the captured fluids.

摘要： A method for data processing (250) includes transforming measurement data acquired in the time domain during an oilfield operation into a second domain to produce transformed data (251); identifying distortions in the transformed data (252); removing the distortions from the transformed data (252); and transforming back from the second domain to the time domain to produce cleaned-up data. The transforming measurement data may use a Fourier transform or a wavelet transform. The method may further include compressing the cleaned-up data (253) or reconstructing signals from the cleaned-up data (254). A method for data processing includes decomposing measurement data, which are acquired in an oilfield operation, using a low pass filter to produce a first dataset; decomposing the measurement data using a high pass filter to produce a second dataset; removing distortions from the second' dataset to yield a corrected second dataset; and reconstructing a corrected dataset from the first dataset and the corrected second dataset.

摘要： An optical spectrometer includes a near black body light source, a reference detector in a first optical path and a single measurement detector in a second optical path. A sample cell including a fluid flow line may be positioned in the second optical path upstream of the measurement detector.
