InSitu Color Reservoir Fluid Color Sensor

Overview Library

Downhole fluid analysis using a 20-channel filter array spectrometer to determine fluid color

With optical filters improved for high-temperature performance, the InSitu Color reservoir fluid color sensor uses the extended measurement range of the Insitu Fluid Analyzer system's 20-channel filter array spectrometer to determine fluid color. The color measurement supports fluid identification, determination of asphaltene gradients, and pH measurement.

Measurement reliability and QC

The reliability of the measurement is supported by continuous real-time autocalibration, application of a contamination algorithm that uses all the spectrometer channels, and a coated-window detection flag for enhanced QC.
