Abstract: A method and apparatus for analyzing solubility of asphaltenes of a hydrocarbon fluid sample involves a sequence of operations including: i) performing microfluidic mixing operations that form a mixture that includes the hydrocarbon fluid sample, a solvent that dissolves asphaltenes and a precipitant that precipitates asphaltenes; ii) using microfluidic processes that result in precipitation of asphaltenes from the mixture resulting from i); iii) performing microfluidic filtering operations that remove precipitated asphaltenes resulting from ii) and passes permeate; and iv) performing optical spectroscopy on the permeate resulting from iii). The operations of i)-iv) can be repeated over iterations that vary the amount of solvent relative to the precipitant in the mixture. These iterations can cause varying fractional precipitation of asphaltenes in each given iteration.

Abstract: A method improves the capability for testing a fluid sample, e.g. testing a reservoir sample of hydrocarbon fluid. The methodology comprises positioning a capillary electrophoresis system within an enclosed chamber system. The enclosed chamber system preserves the desired downhole reservoir conditions during testing of the reservoir sample. In some applications, the reservoir sample is divided into a plurality of capillaries of the capillary electrophoresis system to enable testing of the reservoir sample with different types of detectors in one capillary electrophoresis system. The method can also be applied to depressurized reservoir samples.

Abstract: In order to determine a volume thermal expansion coefficient of a liquid, a sample of the liquid is placed inside a cell of a calorimeter followed by an incremental increase of pressure inside the cell containing the liquid. After each pressure increase heat flow into the cell and volume of the liquid are measured. Based on results of the measurements of the heat flow and accounting for initially evaluated cell volume, the volume thermal expansion of the liquid is determined.

Abstract: An optical sensor and corresponding method of operation can detect a phase transition and/or related property of a hydrocarbon-based analyte. The optical sensor includes an optical element with a metallic film coupled or integral thereto, with a sample chamber holds the hydrocarbon-based analyte such that the hydrocarbon-based analyte is disposed adjacent the metallic layer. The optical sensor further includes a light source configured to direct light through the optical element such that the light is reflected by the metallic layer under conditions of surface plasmon resonance. The optical sensor analyzes the reflected light to detect a phase transition and/or related property of a hydrocarbon-based analyte.
