Degradable polymer additives are provided. The degradable polymer additives include a tracer functional group that is bonded to a base polymeric component by a hydrolysable covalent bond. The base polymeric component is a polysaccharide. The tracer functional group is selected from the group comprising a halogen-containing functional group, a substituted heterocyclic aromatic group, and combination thereof. A method utilizing the degradable polymeric additives in an altered drilling fluid is provided. Such a method includes introducing the altered drilling fluid into a wellbore and recovering an associated wellbore cutting from a depleted drilling fluid.
A degradable polymeric additive comprising a tracer functional group that is bonded to a base polymeric component by a hydrolysable covalent bond, where the base polymeric component is a polysaccharide and where the tracer functional group is selected from the group consisting of a halogen-containing functional group, a substituted heterocyclic aromatic group, or a combination thereof.
