Abstract: Compositions containing a transporter component and a signaling component and a method for using said compositions for analyzing porous media and flowing liquid streams, specifically for measuring pressure, temperature, relative abundance of water, pH, redox potential and electrolyte concentration. Analytes may include petroleum or other hydrophobic media, sulfur-containing compounds. The transporter component includes an amphiphilic nanomatenal and a plurality of solubilizing groups covalently bonded to the transporter component. The signaling component includes a plurality of reporter molecules associated with the transporter component. Said reporter molecules may be releasable from the transporter component upon exposure to at least one analyte. The reporter molecules may be non-covalently associated with the transporter component, or the reporter molecules are covalently bonded to the transporter component.

Abstract: A method for inhibiting scale formation in an oil or gas well is provided. Specifically, the method is a novel "squeeze" application. The squeeze comprises injecting three solutions into the oil or gas well: (1) the preflush solution, (2) the pill solution, and (3) the overflush solution. After the injection of the three solutions, the well is shut-in for about 24 to about 48 hours. The squeeze application is useful regardless of whether the mechanism for inhibitor fixation is adsorption or precipitation.
