Abstract: A composition of matter including a fluorescent assembly and a drilling fluid is provided. The fluorescent assembly includes a matrix material and a plurality of fluorophores held within the matrix material and has an average particle size of at least one millimeter. A method includes introducing the fluorescent assembly into a drilling fluid and circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the fluorescent assembly interacts with the formation cuttings, creating tagged cuttings. The method further includes collecting returned cuttings from the circulating drilling fluid at a surface of the well, detecting the presence of the fluorescent assembly 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.

Abstract: Techniques for correlating a depth of drill bit cuttings include circulating a drilling fluid into a wellbore during a drilling process to form the wellbore in a subterranean formation; circulating a portion of uniquely identifiable particles from a container into the drilling fluid during the drilling process; circulating a return drilling fluid that includes the drilling fluid, cuttings from the subterranean formation, and the uniquely identifiable particles; separating the drilling fluid from the cuttings from the subterranean formation and the uniquely identifiable particles; capturing at least one image of the separated cuttings and the uniquely identifiable particles; and determining, based on the image, a depth of the subterranean formation.

Abstract: 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.

Abstract: A composition that includes a fluorescent metal-organic framework (MOF) and a drilling fluid is provided. The MOF includes a porous, crystalline structure and a fluorescent source. A method includes introducing a MOF into a drilling fluid and circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the fluorescent MOF interacts with the formation cuttings, creating tagged cuttings. The method further includes collecting returned cuttings from the circulating drilling fluid at a surface of the well, detecting the presence of the fluorescent MOF 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.

Abstract: A composition including a fluorescent polymer tag and an aqueous-based drilling fluid is provided. Also provided is a method of determining drill depth of recovered drill cuttings. The method includes introducing a fluorescent polymer tag into a drilling fluid, the fluorescent polymer tag includes the composition having the fluorescent compound linked to the polymer. The method then includes circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the fluorescent polymer interacts with the formation cuttings, creating tagged cuttings. The returned cuttings are collected from the circulating drilling fluid at a surface of the well. The method then includes detecting the presence of the fluorescent polymer tag on the returned cuttings to identify the tagged cuttings, and correlating the tagged cuttings with the drill depth in the well at a time during the drilling operation.

Abstract: A method for wellbore treatment. The method including preparing an encapsulated treatment agent via polymerization, feeding the encapsulated treatment agent into the wellbore, delivering the encapsulated treatment agent to a desired depth within a formation in the wellbore, activating an acoustic or an electromagnetic source at the desired depth within the formation, and generating an acoustic field or an electromagnetic field. The acoustic field or electromagnetic field activates the encapsulant thereby releasing the treatment agent into the wellbore and a desired depth.
