Original Abstract Submitted
Techniques for identifying drill cuttings include drilling a wellbore; during the drilling, circulating a drilling fluid that includes a plurality of tracer pills, where each tracer pill includes a shell or coating formed of a thermoresponsive material and a tracer material enclosed within the shell; during the drilling, removing cuttings such that the cuttings become entrained within the drilling fluid; attaching the tracer material of the tracer pills to the cuttings entrained within the drilling fluid by releasing the tracer material from the shells; and circulating the drilling fluid including the cuttings with the attached tracer material through the wellbore and uphole toward a terranean surface.
