Abstract
In some embodiments, an apparatus and a system, as well as a method and an article, may operate a pump to obtain a formation fluid sample from a formation adjacent to a wellbore disposed within a reservoir, to detect a phase behavior associated with the fluid sample, and to adjust the volumetric pumping rate of the pump while repeating the operating and the detecting to maintain the pumping rate at a maintained rate, above which the phase behavior changes from a substantially single phase fluid flow to a substantially multi-phase flow. Additional apparatus, systems, and methods are disclosed.

An apparatus, comprising:
- a pump to obtain a formation fluid sample from a formation adjacent to a wellbore disposed within a reservoir;
- a multi-phase flow detector to detect a phase behavior associated with the fluid sample;
- and
- a processor to adjust a volumetric pumping rate of the pump to maintain the pumping rate at a maintained rate, above which the phase behavior changes from a substantially single phase fluid flow to a substantially multi-phase flow.
A system, comprising:
- a downhole tool;
- a pump and a multi-phase flow detector at least partially housed by the downhole tool, the pump to obtain a formation fluid sample from a formation adjacent to a wellbore disposed within a reservoir, and the multi-phase flow detector to detect a phase behavior associated with the fluid sample;
- and
- a processor to adjust a volumetric pumping rate of the pump to maintain the pumping rate at a maintained rate, above which the phase behavior changes from a substantially single phase fluid flow to a substantially multi-phase flow.
