Abstract

Described herein are variable-volume reservoir (e.g., syringe pump) based processes and systems usable to characterize samples of reservoir fluids, without having to first transport the fluids to the surface. Variable-volume reservoirs are used, for example, for one or more of storing reactants, controlling mixing ratios and storing used chemicals. The processes and systems can be used in various modes, such as continuous mixing mode, flow injection analysis, and titrations. A fluid interrogator, such as a spectrometer, can be used to detect a change in a physical property of the mixture, which is indicative of an analyte within the mixture. In at least some embodiments, a concentration of the analyte solution can be determined from the detected physical property.
