METHOD AND MATERIALS FOR EXTRACTION OF OIL-SOLUBLE ORGANIC MOLECULAR TRACERS FROM OIL PHASES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17549062 titled 'METHOD AND MATERIALS FOR EXTRACTION OF OIL-SOLUBLE ORGANIC MOLECULAR TRACERS FROM OIL PHASES
Simplified Explanation
The patent application describes functionalized fluorescent tracers and methods for extracting them from oil phases and drilling fluids. The tracers can be extracted using a silica-based sorbent that has both hydrophobic and ionic functional groups. The ionic functional group can be positively or negatively charged. The method involves mixing the sorbent with an oil phase sample containing the tracer, recovering the sorbent, and dispersing it in an organic solvent. The pH of the organic solvent can be adjusted to aid in the extraction process.
- Functionalized fluorescent tracers and methods for extracting them from oil phases and drilling fluids are provided.

Original Abstract Submitted
Functionalized fluorescent tracers, compositions, and methods for extracting the functionalized fluorescent tracers from oil phases and other wellbore or drilling fluids are provided. In some implementations, a sorbent for extracting tracer molecules from a fluid includes a silica-based sorbent. The silica-based sorbent includes a hydrophobic functional group and an ionic functional group. In some implementations, the ionic functional group is positively charged. In some implementations, the ionic functional group is negatively charged. A method of extracting a functionalized dye from an oil phase includes mixing a sorbent for extracting tracer molecules with an oil phase sample that includes a functionalized fluorescent tracer, recovering the sorbent from the oil phase, and dispersing the sorbent in an organic solvent. In some implementations, the method includes lowering the pH of the organic solvent. In some implementations, the method includes raising the pH of the organic solvent.
