InSitu Color

Reservoir fluid color sensor

Representation of fluid sampling at the reservoir

The color of hydrocarbons

The InSitu Color reservoir fluid color sensor of the InSitu Fluid Analyzer system uses the 20-channel filter array spectrometer to determine the optical density, which is expressed as a dimensionless numerical value for the color characteristics of the fluids, in real time downhole at reservoir conditions.

The color measurement supports fluid identification, determination of asphaltene gradients, and pH measurement.

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.
