Systems, tools, and methods for determining a fluid property based on EPR spectroscopy on an induced paramagntic response from a fluid

A method of determining at least one property of a fluid flowing through a system, comprising:

• exposing the fluid to electromagnetic energy to induce at least one paramagnetic response from at least one diamagnetic species present in the fluid flowing through the system;
• performing electron paramagnetic resonance (EPR) spectroscopy on the at least one paramagnetic response to generate an EPR spectrum;
• determining the at least one property of the fluid based on an attribute of the EPR spectrum;
• and
• based on the attribute of the EPR spectrum, adding an inhibitor composition, a surfactant, a reagent, or combinations thereof to the fluid.

An apparatus for determining at least one property of a fluid configured to flow through a system, comprising:

• a source of electromagnetic energy configured to induce at least one paramagnetic response from at least one diamagnetic species present in the fluid;
• an electron paramagnetic resonance (EPR) spectrometer configured to perform EPR spectroscopy on the at least one paramagnetic response to generate an EPR spectrum;
• and
• at least one processor coupled to the EPR spectrometer and the source of electromagnetic energy, the at least one processor being configured to determine the at least one property of the fluid based on the EPR spectrum.

A non-transitory computer-readable medium storing instructions that, when executed on a processor, perform operations for detecting a property of a fluid flowing through a system, the operations comprising:

• exposing the fluid to electromagnetic energy to induce at least one paramagnetic response from at least one diamagnetic species present in the fluid flowing through the system;
• performing electron paramagnetic resonance (EPR) spectroscopy on the at least one paramagnetic response to generate an EPR spectrum;
• and
• determining at least one property of the fluid based on the EPR spectrum.
