Abstract
A method of analyzing a well sample for a well treatment additive includes contacting the sample with functionalized metallic nanoparticles that contain metallic nanoparticles functionalized with a functional group including a cyano group, a thiol group, a carboxyl group, an amino group, a boronic acid group, an aza group, an ether group, a hydroxyl group, or a combination including at least one of the foregoing; irradiating the sample contacted with the functionalized metallic nanoparticles with electromagnetic radiation at a selected energy level; measuring a Raman spectrum emitted from the sample; and determining presence, type or concentration of the well treatment additive in the sample from the Raman spectrum.
