Abstract
A composition of matter includes a core-shell quantum dot particle having an inorganic core and an organic shell and drilling fluid. A method includes introducing a core-shell quantum dot particle having an inorganic core and a polymer shell into a drilling fluid, circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the core-shell quantum dot particle interacts with the formation cuttings, creating tagged cuttings, collecting returned cuttings from the circulating drilling fluid at a surface of the well, detecting the presence of the core-shell quantum dot particle on the returned cuttings to identify the tagged cuttings, and correlating the tagged cuttings with a drill depth in the well at a time during the drilling operation.
