ABSTRACT:
Methods and apparatus for decreasing a density of a downhole fluid are described. An example apparatus to analyze a downhole fluid includes a chamber to decrease a density of at least a portion of a sample of a downhole fluid. Additionally, the example apparatus includes a sensor to measure a pressure of at least the portion of the sample in the chamber. Further, the example apparatus includes a fluid measurement unit to measure a characteristic of at least the portion of the sample based on a relationship between the pressure of at least the portion of the sample in the chamber and a predetermined pressure. Further yet, the example apparatus includes a control unit to determine a parameter of the downhole fluid based on the characteristic.
