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. InSitu Fluid Analyzer system integrates multiple InSitu Family downhole quantitative fluid properties measurements and sensors. Investigate and quantify fluids at their source: your reservoir.
