Single-phase assurance and fluid typing for downhole fluid analysis and sampling

The InSitu Fluorescence reservoir fluid fluorescence sensor detects free gas bubbles and retrograde condensate liquid dropout for single-phase assurance while conducting downhole fluid analysis (DFA) and sampling. Fluid type is also identified. The resulting fluid phase information is especially useful for defining the difference between retrograde condensates and volatile oils, which can have similar GORs and live-oil densities.

Phase status in real time

Because the fluorescence measurement is also sensitive to liquid precipitation in a condensate gas when the flowing pressure falls below the dewpoint, it can be used to monitor phase separation in real time to ensure the collection of representative single-phase samples.

Dual Measurements Deliver Single-Phase Assurance

Downhole reflection and dual fluorescence measurements provide assurance that the reservoir fluid is in single phase before DFA sampling.
