Abstract
A fluid analyzer for a downhole tool positionable in a wellbore penetrating a subterranean formation is provided. The fluid analyzer includes an optical sensor positioned in the downhole tool to receive a downhole fluid therefrom. The optical sensor includes an optical cell to measure properties of the downhole fluid in a flowline of the downhole tool, and has a wavelength range. The fluid analyzer also includes a calibration fluid having a liquid that absorbs outside of the wavelength range, and a calibrator. The calibrator includes a fluid source housing the calibration fluid and at least one valve. The fluid source is operatively connectable to the optical sensor to provide the calibration fluid thereto whereby the calibration fluid is measureable by and calibratable to the optical sensor.
