Real-time downhole fluid analysis

InSitu Fluid Analyzer

Real-time fluid answers from a downhole laboratory

By investigating fluids at their source, you gain a deeper insight into fluid composition and distribution for improving your understanding of the reservoir. The InSitu Fluid Analyzer™ real-time downhole fluid analysis system is more than just a wireline tool; it is essentially a fully functioning laboratory downhole that provides real-time comprehensive representative characterization of reservoir fluids at reservoir conditions. The system integrates InSitu™ downhole quantitative properties measurements, which features various sensors. Along with flowline pressure and temperature, the modular downhole fluid analysis portfolio includes a wide range of metrology.
