摘要： Methods and apparatus for downhole analysis of formation fluids by isolating the fluids from the formation and/or borehole in a pressure and volume control unit that is integrated with a flowline of a fluid analysis module and determining fluid characteristics of the isolated fluids. Parameters of interest may be derived for formation fluids in a static state and undesirable formation fluids may be drained and replaced with formation fluids that are suitable for downhole characterization or surface sample extraction. Isolated formation fluids may be circulated in a loop of the flowline for phase behavior characterization. Real-time analysis of the fluids may be performed at or near downhole conditions.

摘要： A downhole fluid analysis system comprises an input light signal that is directed through a fluid sample housed in a sample cell. The input light signal may originate from a plurality of light sources. A light signal output from the sample cell is then routed to two or more spectrometers for measurement of the represented wavelengths in the output light signal. The output of the spectrometers is then compared to known values for hydrocarbons typically encountered downhole. This provides insight into the composition of the sample fluid. Additionally, the input light can be routed directly to the two or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole.

摘要： An optical fluid analyzer tool may have an evaluation flowline which receives a flow of fluid from a geotechnical formation and may have a cleanup flowline which receives another flow of fluid from the geotechnical formation. A flow routing system may be connected to the evaluation flowline and may be connected to the cleanup flowline. The flow routing system may establish isolated flow or commingled flow for the evaluation flowline and may establish isolated flow or commingled flow for the cleanup flowline. A sample chamber may be connected to the evaluation flowline and may be connected to the cleanup flowline. A first pump module may draw the fluid from the geotechnical formation, and an optical fluid analyzer connected to the cleanup flowline and the evaluation flowline may analyze the fluid.

摘要： Example methods and apparatus to detect phase separation in downhole fluid sampling operations are disclosed. An example method to detect a phase separation condition of a fluid from a subterranean involves obtaining a sample of the fluid, measuring a first characteristic value of the sample, measuring a second characteristic value of the sample and comparing the first characteristic value to a first reference value associated with a single-phase condition of the fluid to generate a corresponding first comparison result. The example method then compares the second characteristic value to a second reference value associated with the single-phase condition of the fluid to generate a corresponding second comparison result and detects the phase separation condition of the fluid based on the first and second comparison results.
