Abstract: A fluid monitoring system for monitoring a concentration of nanoparticle additives in wellbore treatment fluid using X-ray fluorescence (XRF) can include a preparation unit and an analysis unit. The preparation unit can generate a representative sample of the wellbore treatment fluid by performing a separation process with respect to a sample of the treatment fluid. The analysis unit can chemically analyze the subset of the treatment fluid sample using XRF to generate radiation intensity data of the representative sample. Based on the radiation intensity data, the fluid monitoring system can determine that the concentration of the nanoparticle additives is outside of a predefined range. In response to determining that the concentration of the nanoparticle additives in the representative sample is outside of the predefined range, the fluid monitoring system can perform a mitigation operation to modify the concentration of the plurality of nanoparticle additives to be within the predefined range.

Abstract: Techniques described herein can be used to quantify additives of wellbore fluids using laser induced breakdown spectroscopy. For example, a method can involve acquiring a sample of wellbore fluid from a wellbore. The wellbore fluid can include an additive. The sample can be processed to separate the wellbore fluid into a liquid sample and a solid sample. A laser induced breakdown spectroscopy device can identify a chemical composition of the liquid sample or the solid sample. A concentration of the additive in the wellbore fluid can be determined based on the chemical composition of the liquid sample or the solid sample. An adjustment to a composition of the wellbore fluid can be performed based on the concentration of the additive in the wellbore fluid.
