Abstract: Systems and methods presented herein relate to real-time analysis of production chemicals at wellsites utilizing capillary electrophoresis (CE) analysis of produced water in-situ and in substantially real-time to determine the effectiveness and efficiency of production chemicals injected into wells. For example. systems and methods presented herein include CE equipment configured to receive sample fluids from production fluids extracted from various locations of wellsites, and to perform CE analysis to generate data relating to one or more fluid properties of the sample fluids. The systems and methods presented herein also include an analysis and control system configured to detect and quantify individual components of production chemicals injected into wells of the wellsites based at least in part on the data relating to the one or more fluid properties of the sample fluids.
