CHEMICALLY TAGGED POLYMERS FOR SIMPLIFIED QUANTIFICATION AND RELATED METHODS.

摘要

Method comprising the steps of obtaining a sample of a return drilling fluid, the return drilling fluid containing a tagged detectable additive, the tagged detectable additive comprising a polymer comprising at least one chemical tag bonded to the polymer; and determining a concentration of the tagged detectable additive in the return drilling fluid based on a spectroscopic signal of the sample. The tagged detectable additive may include a polymer comprising at least one chemical tag bonded to the polymer.
