Mobile Wellhead Analyzer for the Determination of Unstable Constituents in Oil-Field Waters

Source

A brine analyzer was designed that measures pH, redox potential (Eh), oxygen, conductivity, sulfide ion (S⁼), HCO₃⁻, CO₃⁼, and carbon dioxide in oil-field water at the wellhead. When oil-field brine samples are collected in the field and transported to the laboratory for analysis, many of the unstable constituents change in concentration. The amount of change depends on the sampling method, sample storage, ambient conditions, and the amounts of the constituents in the original sample. Thus, an analysis of the brine at the wellhead is necessary to obtain reliable data.
