Abstract: Apparatus and methods for obtaining a data response of a fluid as a function of pressure of the fluid, and estimating a dew point pressure of the fluid by detecting an inflection pressure, a downward curve pressure, a characteristic change pressure, and an intersection pressure of the function representative of the data response. The estimated dew point pressure of the fluid based on at least one of the inflection pressure, the downward curve pressure, the characteristic change pressure, and the intersection pressure.

Abstract: A technique facilitates fluid analysis in situ at a downhole location. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine contamination of the sample and to determine other selected characteristics of the sample. The data obtained is then processed to provide a formation volume factor of the oil. The testing may be performed at selected stations along the borehole to facilitate rapid development of a realistic model of fluid distribution and property variation in the reservoir, thus enabling an improved oil recovery strategy.

Abstract: Optical window assemblies are provided. An example apparatus includes a first fixture defining a fluid flow passageway. The example apparatus also includes a second fixture defining an aperture. The second fixture is coupled to the first fixture. A first optical window is disposed in the aperture. The first optical window has a first end and a second end. The first end is to be in contact with fluid in the fluid flow passageway, and a cross-sectional size of the first optical window decreases from the first end toward the second end along a portion of the first optical window.
