Cost-efficient tracers with fast and simple detection and quantification methods at low detection limits via on-site detection is a current industrial target for state-of-the-art tracer tests. To bridge the gap between the desired tracer properties and detection limits, we developed a broad spectrum of robust and cost-efficient fluorescent tags to innovate the current reservoir management practices. We engineered new tracers and extended tracer test applications for on-site real-time well-drilling monitoring to label drill cuttings as they are made at the drill-bit face to improve drill-cuttings depth correlation. These developed fluorescent tracers not only have the low detection limits of fluorescent spectroscopy techniques but also allow for automated detection at minimal concentrations of 0.025–0.037 mol.%. These developed tracers allow us to detect the real-time drilling depth, thereby enhancing hydrocarbon recovery. Thus, the reported innovative fluorescent-based tracing approach would (1) reduce drilling depth correlation uncertainty, (2) optimize well placement, and (3) maximize oil production.
