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.
