    摘要： A method of fluid testing includes pressurizing a fluid testing system, disposed at a subterranean location under high pressure compared to a surface pressure, to achieve a desired pressure differential between the high pressure and an internal pressure of the fluid testing system. The fluid testing system includes a capillary electrophoresis system and one or more test fluid reservoirs. The method also includes directing test fluid from the one or more test fluid reservoirs into capillaries to condition the capillaries. The method further includes directing sample fluid into the capillaries for testing while at the subterranean location.

    摘要： The current application discloses methods and systems to analyze on-site and in real-time or quasi real-time the composition of the well fluid before or during use or disposition. The method is based on capillary electrophoresis (CE) and does not require the addition of tracers into the well fluid or additive. Based on the significance of each additive on the well fluid properties, it can be decided to determine the concentration of all additives or only one or a limited number of the additives present in the fluid, and the concentrations can be adjusted as needed to reach the desired target concentration(s).
