1. A method of treatment with scale inhibitor, comprising:
adding scale inhibitor to source water to give injection water;
conveying the injection water in a surface conduit to an injection well for injection into an oil reservoir in a subterranean formation;
obtaining a sample of the injection water, wherein the sample of the injection water comprises suspended solids;
analyzing the suspended solids via energy dispersive x-ray spectroscopy (EDS), x-ray diffraction (XRD), or x-ray fluorescence (XRF), or any combinations thereof; and
pumping the injection water through a wellbore of the injection well into the oil reservoir.
