The systems and methods can include adding each of the plurality of polymeric taggants in a repeating sequence to a circulating drilling fluid while drilling the well and taking a sample drill cuttings carried by the circulating drilling fluid. The systems and methods can also include measuring concentrations of individual polymeric taggants attached to the drill cuttings in the sample and identifying a depth associated with the sample based on the measured concentrations of individual polymeric taggants and on the sequence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Surface logging wells using depth-tagging of cuttings","description":"Systems and methods of surface logging a well use a plurality of polymeric taggants distinguishable from each other.
