InSitu Fluid Analyzer

Real-time downhole fluid analysis system

Real-time fluid answers—No more waiting for laboratory analysis

The InSitu Fluid Analyzer real-time downhole fluid analysis (DFA) system integrates various sensors making quantitative fluid properties measurements to deliver a comprehensive characterization of reservoir fluids at reservoir conditions.

Quantified, accurate fluid data that was previously unachievable from wireline logs or the laboratory analysis of collected samples is now possible:

  • hydrocarbon composition (C1, C2, C3–C5, and C6+)
  • gas/oil ratio (GOR)
  • live-oil density and viscosity
  • CO2
  • pH of water (aquifer, connate, injection, or water-based mud [WBM] filtrate)
  • reservoir fluid color
  • free-gas detection
  • downhole fluorescence (dew precipitation in retrograde gas condensates)
  • flowline pressure and temperature (regime of the sample chamber, not the probe)
  • resistivity of reservoir water
  • oil-based mud (OBM) filtrate contamination.
